Introduction
Congratulations on your purchase of DGT Pi, the world’s only all-in-one programmable chess
computer with integrated chess clock that turns your USB, Smart Board or DGT Bluetooth e-Board
into your best sparring partner. Connected together, the e-Board and DGT Pi offers a unique way to
play chess, to train and to analyse games and positions by using a real chess board and pieces.
The DGT Pi is a chess computer that runs various chess engines on a Raspberry Pi, which is built
into the DGT 3000, the most advanced chess clock currently available. Many different game
settings and playing levels can be selected. The display guides you through the menu settings and
informs you during the game, showing clock times, game moves and hints.
To start a game, simply connect DGT Pi to your DGT e-Board and place all the pieces in the starting
position. Then just make your first move to start a game. During thinking time, the display shows a
countdown timer. When DGT Pi calculated its next move this move will be shown on the display.
Now make the computer move on the e-Board and it will again be your turn to move. There is no
need to press the clock’s lever after each move as you would do in a regular chess game. The
countdown clock automatically switches sides when a move is made on the e-Board. Pressing the
lever during a game will result in a change of colours allowing you to switch from playing with
white pieces to playing with black pieces and vice versa.
DGT Pi can also be used as a DGT3000 chess clock only. Consult the separate DGT3000 manual for
instructions. Two batteries (included) should be installed at all times even when the device is used
as a chess computer and the external power adapter is connected. When using DGT Pi as a chess
clock it is not necessary to connect the power adapter.
The purpose of this manual is to explain the functionality of the dedicated DGT Pi chess computer.
It describes how to connect DGT Pi to your DGT e-Board and explains how to pre-define settings
and set-up your chess games. You can use DGT Pi for training purposes or experience great chess
games against a range of different chess engines with competitive Elo ratings. It is also a valuable
self-teaching tool for beginners.
This manual is based on the DGT Pi PicoChess software version 0.9L Free upgrades of implemented
features and supported engines will be made available from time to time. Such future software
versions and new features may not be covered by this manual. Within this context, also read the
disclaimer at the end of this manual. For future software and manual updates, please regularly
check our website www.digitalgametechnology.com or register for our mailings at the product
registration page of our website.

the markings visible at the bottom of the battery compartment. It is recommended to remove the
batteries when the device is not used for longer periods to avoid possible damage caused by a
leaking battery. When the battery symbol is shown on the display the DGT Pi can still be used
for several long games though it is recommended to replace the batteries for new ones.
Important:
•The batteries included are non-rechargeable and should not be recharged.
•Do not use rechargeable batteries in this product.
•Place the batteries in the battery compartment with the correct polarity.
•A dead battery should be removed from the product immediately.
•Never short circuit a battery.
Performance
This DGT Pi version is based on the Raspberry Pi 3 hardware which has a built-in Bluetooth®- and
Wi-Fi® functionality. This product is a stand-alone product with full wireless functionality. No
additional dongles are required. The power supply is a 2 Ampere 5 Volt version to be connected to
the DGT Pi via the micro USB connector at the rear-side.
Using DGT Pi with your DGT e-Board
5
DGT Pi is exclusively designed to be used in combination with a DGT e-Board or a DGT Smart Board.
With a DGT board you will be able to enjoy playing against a computer using a real wooden chess
board. Moves performed on the e-Board are detected by the electronic detection hardware inside
the e-Board and communicated to the DGT Pi. DGT has various e-Boards and electronic chess set
options available so you can choose a set-up to suit your personal preferences.
DGT Pi can be connected with a USB e-Board using the USB cable (included). To connect DGT Pi
with a Bluetooth e-Board there are two options:
Wired: via the USB cable (included)
Wireless: via a Bluetooth connection (DGT Pi has a built-in Bluetooth wireless transmitter)
NOTE: To connect a Smart Board use the 3 meter USB-C cable that came with your Smart Board.
USB or Bluetooth connection?
The four USB ports are hidden behind the bottom lid at the left side of the DGT Pi. This lid can
easily be removed by pressing on the bottom side marking and simultaneously moving the lid side
wards. Use the supplied USB cable and connect it between the USB connector of the DGT e-Board
and to one of the free USB ports of the DGT Pi. See below a picture how the DGT Pi, for example,
should be connected to a DGT Smart Board:
DGT Pi has a built-in Bluetooth transmitter which allows you to connect DGT Pi to a DGT Bluetooth
e-Board via a wireless Bluetooth connection. To use your Bluetooth e-Board with DGT Pi please
make sure the board is switched on. After powering up DGT Pi, it will start searching for a DGT
Bluetooth e-Board and automatically connect to it if the e-Board is free to use. Do note that the
Bluetooth e-Board itself will not be charged when connected via Bluetooth only and the e-Board
may switch off during a game if its internal battery runs low on power. To prevent this from
happening we recommend to always connect your Bluetooth e-Board to the DGT Pi by using the
6
provided USB cable. If you do not wish to use the USB cable please ensure the battery from your
Bluetooth e-Board is fully charged.
Starting DGT Pi
Power up DGT Pi by connecting the power adapter to the micro USB connection at the back of the
DGT Pi and place the AC outlet socket in a free AC wall outlet. Adapters for various international
power sockets are included. It is also possible to use an external power bank (not included).
The DGT Pi and the display functions will start automatically and it is not required to start DGT Pi by
pressing the bottom power switch.
After starting the DGT Pi the display shows the currently selected pre-set clock times. DGT Pi is now
ready for a game, either using default settings or previously made game settings. You can change
the settings using the clock buttons or using the extra queens on the e-board. Detailed descriptions
on where to place a queen for each option will be discussed later in this manual.
Description of the DGT Pi start-up process:
1. Once the power adapter is connected, DGT Pi will respond with the start-up message: “DGT
Pi”followed by “PicoChess” + Software version.
2. The reboot process for the Raspberry Pi computer may take up to 20 seconds.
3. The DGT Pi will start searching for an e-Board. The display might show “no e-Board” when no
e-Board is connected. When an e-Board has been found it will show:
a) The message “BT” + the e-Board serial number when connected to a Bluetooth e-Board.
b) The message “USB e-Board” when already connected to a USB e-Board or Smart Board.
4. If a connection cannot be established, DGT Pi will continue to search for any nearby e-Board.
The message ‘’no e-Board’’ will be shown until a USB board / Smart Board is connected or a
Bluetooth e-Board connection is established.
5. Once an e-Board has connected to an e-Board and you have placed all pieces in the starting
position, DGT Pi will respond with the default or selected time setting on the display. For
example it may show “05.00 05.00”.
6. When the starting position has not fully been set up, DGT Pi will regularly display “Set Pieces”
and will wait until all pieces are properly set up in the starting position (Please ensure that
the extra queens are NOT yet placed on the board).
7. You are now ready to play chess against the DGT Pi. To adjust your chess preferences, you
can change the settings by using the clock menu buttons or by placing the extra black or
white queen on the board. Details are described elsewhere in this manual.
Playing a game against a DGT Pi engine
7
Important notes before starting a game:
1. If you are using an e-Board with indices, we recommend to always placing the white pieces
on row 1 and 2 and the black pieces on row 7 and 8. This ensures that the coordinates
shown on the DGT Pi display match the coordinates shown on the side of your board.
2. If DGT Pi does not respond to menu keys or game changes within 20 seconds after starting,
the device may be locked. Please try to restart it by pressing the ON/OFF key located on the
bottom of the DGT Pi.
3. If this does not lead to a correct restart, unplug and reconnect the micro USB power connector
to force a full reboot of DGT Pi. Wait approximately 20 seconds for the device to reboot.
Playing and training modes
DGT Pi has several playing and training modes. Below is a summary of the options currently
implemented.
Normal mode: You can play against one of the selected DGT Pi engines. The clock displays the
remaining thinking time for both sides. Press the –key to show the computer evaluation of
the position, expressed in centipawns (see below note for explanation) or press the key to
show a hint (“ponder move”).
Brain mode: This is same as Normal mode but the computer is using the permanent brain to
think ahead during your thinking time as well.
•Analysis mode: DGT Pi is only observing the game and does not play itself. The clock
continuously displays the best move for the side to play.
•Kibitz mode: DGT Pi is only observing the game and does not play itself. The clock
continuously displays the computer evaluation of the position on the board.
•Observe mode: DGT Pi is only observing the game and does not play itself. The clock displays
the remaining thinking time for both sides. Press the –key once to show the position
evaluation. Press the key to show a hint.
•Ponder mode: Ponder mode combines the “Analysis” & “Kibitz” mode alternating every 2
seconds between each mode. In addition to the normal Kibitz mode, the DGT Pi will display
brute force depth together will the current value.
•Remote play mode: This mode allows you to play against other players or engines over the
internet. Be aware that this mode is NOT YET supported in software version 0.9L.
Notes:
Normal mode is the “regular”chess game mode and, after restart, the default setting on DGT Pi. If
you have selected one of the other modes, you can return to normal mode using the menu buttons
and toggle through the settings or place the extra white queen on a5.

Centipawns are the value of 1/100th of a pawn. It is a theoretical unit most chess engines use to
assess positions. The position score is the computer evaluation of the position on the chess board
and it is expressed in a number of centipawns. The unit is useful for expressing small advantages or
disadvantages between black and white. For example if white is one pawn ahead and black does
not have any compensation for the loss of his pawn (usually some positional advantage), an engine
will generally consider white to be 100 centipawns better. Often this would be expresses as +1.00
pawns though on DGT Pi it is currently expressed as +100 centipawns. If, on the other hand, black
had some compensation, an engine could calculate white to have an advantage of perhaps 29
centipawns (+0.29 pawns). Note that the position score will always be displayed in centipawns
from white’s perspective. For example, if DGT Pi displays a score of +33, then the white player is 33
centipawns (or 0.33 pawns) ahead. A negative score means that the black player is ahead.
Position menu
DGT Pi supports several position modes:
Switching sides: DGT Pi has an option to switch sides. You can select to play with white or let
DGT Pi start with white. During an active game, sides can be switched by pressing the lever on
top of DGT Pi. Doing so allows you to take over the game position from DGT Pi. This can be a
good teaching tool to improve your chess skills and learn to play with different, and perhaps,
challenging positions.
•Chess 960: This option, not supported by all installed engines, is used to set up a Chess 960
position. This is a special feature to play Chess 960 or Fischer Random Chess which is a great
alternative way to play chess. Chess 960 is the only other form of chess officially recognized by
the International Chess Federation FIDE and it is played by many chess lovers worldwide. In
Chess 960 the games do not start from the traditional starting position but instead start from
one of 960 random starting positions. It requires players to start thinking about their moves
right from the start thus bypassing any advantage a player may have from learned knowledge
about particular chess openings. Just give it a try once you are more familiar with the normal
play modes.
•Scan board: This option allows you to set up any position on the board that you wish to play
or analyse. Just set up a position and scan the e-Board. Make sure the position you set up
complies with the rules of chess. For example the kings should not be in “check mate” and
pawns that reached the opposite side should be promoted before scanning a board position.
Set up any position you want for play, analysis, train or problem solving.
Time Menu
DGT Pi supports following timing modes:
•Move Time: Select a fixed time per move for the engine between 1 and 90 seconds. DGT Pi
will make a move after the selected time has passed. After performing the computer move it
9
is your turn and the display will show “ok Pico”. In this time mode your own thinking time is
unlimited.
•Game Time: Select a game time between 1 and 90 minutes. Both player and engine receive
the same amount of thinking time to complete their moves. Their clocks will count down
during their turn. Just like in a regular chess game using a regular chess clock. Note that the
lever on top of the clock should not be pressed to indicate the end of each turn; simply
moving the pieces on the board will signal the end of a turn and the other player’s clock will
start counting down automatically.
•Fischer: Select a game time for both players between 1 and 60 minutes with a Fischer
increment time added for each move between 1 and 30 seconds.
Book Menu
DGT Pi supports a wide range of book modes. Books are databases containing various chess
openings. For example: Select “Book” in the menu and then select one of the available books. To
play without opening guidance select “No Book”
Note: The current list of books may change in future software versions.
Engine Menu
DGT Pi includes a wide range of chess engines. Most engines have a level selection option allowing
you to adapt the engine strength to your personal level. The levels can usually be selected between
0 and 20. Elo rating levels may be given but for most engines the levels are not easily to convert to
a comparable Elo rating.
Note: The current list of engines may change in future software versions.
Examples of the estimated Elo strengths for some of the levels of the StockFish8 engine are:
•Level 3 estimates about 1000 Elo (Absolute beginner)
•Level 9 estimates about 1750 Elo (Mediate club player)
•Level 20 estimates about 3100 Elo (Grandmaster)
System Menu
This menu section is used to read out and adjust several DGT Pi system functions.
•You can check your current installed software version.
•It will show your IP address and check the IP connection (Only for future feature upgrades).
•You can select the sound function and vary between three stages. In the beginning you may
find it helpful to hear many beeps. As you become more familiar with your DGT Pi and hear
too many beeps you can select an option as “Never” or “Sometimes”.
10
•You can select the language. Currently six languages are implemented, English, German,
Dutch, French, Italian and Spanish.
•For Phyton software programmers there is a logfile create option. (This is for software
developers only and beyond the scope of this document)
•A multi lingual voice option is included for the computer and player.
Note: An additional amplified loudspeaker should be connected to the audio output at the
back of the DGT Pi.
•The display option selects various clock display options like ponder interval, confirmation
messages, capital letters and short/long notation.
Setting up a game
To change the settings on DGT Pi there are two methods:
1. Using the menu buttons (easy method)
2. Using the extra black and white queens on the e-Board (fast method)
Both methods have their advantages and are described below.
Game settings using the menu buttons (easy) / extra queens (fast)
The easy method uses the menu buttons at the front of DGT Pi. All menu options can be accessed
and changed by using these buttons. With the easy method it is not necessary to have all chess
pieces in the starting position or to use the extra queens. Just go through the menu by pressing the
menu buttons. For example you can press the middle menu button to force DGT Pi to make a
move. It is possible to change colour by pressing the lever on top of DGT Pi.
Using the extra queens on the e-Board is the fast method to change settings but not all options can
be selected this way. To change settings by using the extra queens, all 32 chess pieces must first be
placed in the starting position. The extra two queens supplied with all DGT electronic chess sets are
used to confirm the settings. Move one of the extra queens over the empty squares of the e-Board
(Remember the other pieces must be in the starting position) and the display will show the setting
option related to that square. The setting will be activated by lifting the extra queen from that
square.
Note: We suggest not switching between engines or change time settings during a running game as
this may lead into unpredictable behaviour. For example in some situations a change in settings
during a game can result in a new game.

“Fast method” using the extra queens
For this method you require the two extra queens supplied with any set of electronic DGT chess
pieces. By placing and lifting one of these queens you can make your menu selections very quickly.
It is not possible to move through all the submenus in the menu. To access all menu- and submenu
options the menu buttons on the front of DGT Pi should be used. The fast method to set DGT Pi is
only possible if all other 32 chess pieces are placed in the starting position. The display will confirm
and show the setting change. Please remove the extra queen to start the game.
Only one of the extra queens (black or white) should be used at the same time. Below is a summary
of all options currently available. Future software updates may result in changes in the display,
added functionality and new features.
Selecting a playing mode
Selecting a playing mode is done with the extra white queen as follows:
a5 Normal mode
b5 Not used
c5 Analysis mode
d5 Kibitz mode
e5 Observe mode
f5 Ponder

Using DGT Pi as a regular DGT3000 clock
DGT Pi can also be used as a normal stand-alone DGT3000 chess clock. It is not necessary to
connect the power adapter when using DGT Pi as a chess clock. To save power we recommend
disconnecting the adapter. It is however necessary to insert the batteries.
You may use DGT Pi as a regular DGT3000 clock when you are playing a regular chess game or
when you play via a chess program on your computer. For more details please read the instructions
supplied with your e-Board. The clock cable that came with your e-Board is required if you wish to
use DGT Pi in combination with the regular DGT e-Board functions and without the DGT Pi
functions. Please note that when using the DGT Pi as a chess computer the clock cable should be
removed.
Software update or re-installation of DGT Pi software
DGT Pi comes with a pre-installed 8Mb SD card which is placed in a slot at the bottom. DGT Pi is
ready to play and normally it is not required to reprogram the installed software. If DGT Pi does not
function properly or a software update is available, reprogramming of the SD card may be required.
To update or re-install the software follow below instructions which require some minor computer
knowledge. If you are not comfortable to do this please ask someone to assist you. Feel free to
check the FAQ section on the DGT website or contact DGT support if you have any questions or
comments.
