Open Source Mobile Operating Systems Board Games

Stockfish is a free, powerful UCI chess engine derived from Glaurung 2.1. Stockfish is not a complete chess program and requires a UCI-compatible graphical user interface (GUI) (e.g. XBoard with PolyGlot, Scid, Cute Chess, eboard, Arena, Sigma Chess, Shredder, Chess Partner or Fritz) in order to be used comfortably. Read the documentation for your GUI of choice for information about how to use Stockfish with it. Stockfish is a 11-time winner of the Top Chess Engine Championship. Stockfish is open source (GPLv3 license). That means you can read the code, modify it, and contribute back. You can use Stockfish on your computer or on your iOS or Android device. So you can get world-class chess analysis, wherever you are. The Stockfish engine features two evaluation functions for chess, the classical evaluation based on handcrafted terms, and the NNUE evaluation based on efficiently updatable neural networks.

Installation files for chess engines that provide the Open Exchange (OEX) format. Links to the source code of the built-in chess engines can be found in the corresponding zip archives. In an APK file, chess engines are always available for the following architectures: arm64-v8a, armeabi-v7a, x86, and x86_64. The installation file takes care of the correct installation based on the hardware used. Newer devices can use the files with the suffix “_arm64-v8.2a-dotprod” in the name. The APK file "Chess Engines Bonus" contains chess engines without embedded networks. Chess engines in this package are not ready to use. The missing network files can be found in the assets directory (just rename apk to zip). The network file must be copied to an appropriate directory (this is usually the app-specific external storage) and specified in the UCI options. Requires a chess app that supports the OEX format (e.g. Chess for Android or DroidFish).

Domination is a game that is a bit like the well known board game of Risk or RisiKo. It has many game options and includes many maps.

Open source chess engines that support the Universal Chess Interface (UCI) protocol or Chess Engine Communication Protocol (XBoard). They are written in the C, C++, Go and Rust programming language. C and C++ based chess engines were generated with Android NDK, Clang and GCC. Go and Rust based chess engines were generated with their correspondent compilers. This was done on different platforms like Linux, Termux and Windows. Every zip archive contains a readme file with further information (e. g. link to the source code). Chess engines are located in the libs directory and are available for arm64-v8.2a-dotprod, arm64-v8a, armeabi-v7a, x86 and x86_64 based devices. If a chess engine supports NNUE (Neural Network Updated Efficiently) technology and the network is not embedded in the binary, you will find the missing network file in the networks directory. Requires a chess app that has full access to the internal memory (e.g. Chess for Android 6.2.1 or DroidFish).

Anywhere Board Games (ABG) allows users to play board and card games on the web in real time on multiple machines (PC, Linux, iPhone, iPad, and Android). ABG runs as a stand-alone PHP app. Unlike other gaming environments, we had a peculiar vision: projecting the main board on our table and using laptops or tablets to control our hands (with other friends joining in remotely). ABG runs on PHP 5 and Apache (which is provided with the Windows installer). It supports flipping, stacking, rotating, rolling, and shuffling of pieces, so most board and card games are playable.
