On The L-ine

A deceptively simple board game with brutal strategic depth. Four AI difficulties, local and online play, and a built-in tutorial to get started fast.

Welcome to On The L-ine, a deeply strategic 4x4 board game inspired by Edward de Bono's classic "L game". Easy to learn in a minute, a lifetime to master.

Each player controls an L-shaped piece, and the two neutral pieces are shared. On your turn, move your L piece to a new spot, then optionally shift a neutral piece. You lose when you have no legal placement. That's it, and yet the game is brutally deep.

GAME MODES • Computer: Four AI difficulty levels, topped by Champion, an AI that has never been beaten • Local: Hand the device to a friend for a tense hot-seat match • Online: Create a private room to play friends anywhere, or jump into the public queue

A built-in tutorial teaches you the rules in under a minute. Play offline or online, anywhere.
