Aart's Android Page
As a fun project, Aart Bik implemented
three board games for Android, which are available for free at
or as direct downloads below.
Chess for Android
Chess for Android consists of a chess engine (a Java version derived
from the C++ engine BikJump) and a GUI.
The application accepts moves through the touch screen, trackball,
or keyboard (e2e4 pushes the king pawn, e1g1 castles king side, etc.).
An optional "move coach" highlights valid user moves
during input and last played engine move. Full game navigation
buttons enable users to correct mistakes or analyze games.
Games import and export as FEN/PGN to and from the clipboard,
load and save as file, are set up through a position editor,
or import as application/x-chess-pgn MIME type on startup.
A draw by stalemate, insufficient material,
the fifty move rule, or threefold repetition is recognized.
The engine plays at various levels (including random, against
itself in auto-play, or free-play, where the game can be used
as a "magnetic chessboard"). The user can play either side and,
independently, view the board from the perspective of white or black.
The application supports the Universal Chess Interface (UCI)
and Chess Engine Communication Protocol (WinBoard and XBoard),
which allows users to play against more powerful third party
engines or even play tournaments between engines (see e.g. these
Engine setup features time control, pondering, infinite analysis, hash tables,
multiple threads, endgame tablebases, and opening test suites.
The application also recognizes Android Chessbase compatible engines.
Details can be found at
UCI and XBoard Protocols for Android.
Engines that can be imported are listed at
UCI and XBoard Engines for Android.

Chess for Android is featured in this cool
Checkers for Android
Checkers for Android consists of an 8x8 checkers
engine (a Java version that evolved into the C++
engine BikMove) and a GUI.
The application accepts moves through the touch screen or
trackball. An optional "move coach" shows all valid user
moves and highlights each last played move. An undo feature
can take back up to eight half-moves to correct mistakes.
The engine plays at various levels (including random and
free-play). By popular request, an option was added to
select between mandatory captures (the official rule) or
optional captures (a common home rule, but without
"huffing", where the piece that should have performed
the capture is forfeited; instead the game simply
continues). The user can play either side and,
independently, view the board from the perspective
of white or black.
See also the Checkers for Android Manual.
Reversi for Android
Reversi for Android consists of a reversi engine (verified
with perft) and a GUI.
The application accepts moves through the touch screen,
the trackball, or through the keyboard. An optional
"move coach" shows all valid moves as ghost stones and
highlights the new and flipped stones after each engine move.
An undo feature can take back up to eight half-moves to
correct mistakes. The engine plays at various levels
(including random and free-play). The user can play either side.
