BluetoothOMG is a package of games, where you can play some board and card games (Chess, Hearts, Spades, Backgammon, and Morris), either offline multi-player via bluetooth with your friends and family or single-player with CPU (NO need for Internet).

Chess: Play Chess with a friend or family member, offline via bluetooth. You both just need to install BluetoothOMG, pick Chess, click Multiplayer, and choose a username. Next, someone creates a group and the other joins the group. If you chose to join a group, you would see the name of the Group-Owner on your screen. You can tap on that name and connect to the Group-Owner automatically through bluetooth. After that, the Group-Owner can start the game.
You can also play Chess, single-player, with CPU. BluetoothOMG uses a converted version of Stockfish9 (from C++ into Java) as Chess-Engine.
