Arimaa is one of the fastest growing modern strategy games. Rules are simple and intuitive enough for kids to play easily, yet there is more than enough strategic depth to satisfy the most demanding gamer. If you enjoy challenging games like Chess, Checkers, Go, or Shogi, discover Arimaa and see why it was chosen in the Discovery Channel's list of the Top 10 Mind-bending Strategy Games and also recommended by Scientific American MIND magazine. “The rules are simple enough for kids to learn, and the game was creative and engaging.” —Frederik Joelving; Scientific American Mind magazine With millions of opening setups to choose from, every game requires creative thinking right from the beginning and no need to memorize openings. It's a never ending puzzle, each game is different. In just the first 10 moves of Arimaa there's more possible games than there are atoms in our universe. “Because the number of possible moves in an Arimaa position (roughly 20,000) is much higher than in chess (about 30 or so), even the fastest computers will not be able to search very far into the tree of possibilities.” —R. Wayne Schmittberger; GAMES magazine This Arimaa app includes a video tutorial to teach the rules of the game making it easy to get started.

A fresh abstract strategy game for players who love chess, checkers, and the thrill of outthinking a worthy opponent. Barrier is a two-player strategy game that's easy to learn in one match and hard to put down after. Your opponent has built two barriers between you and their side of the board. Tear them down, piece by piece, tower by tower, and get two of your pieces across before they do the same to you. Three piece types. A handful of rules. An entire world of tactics between them. WHAT MAKES BARRIER DIFFERENT Unlike chess, there's no single piece you're protecting. Unlike checkers, every capture changes the shape of the board. Barrier rewards players who can read a position, plan several moves ahead, and know when to defend your own barrier versus when to breach your opponents. GAME MODES Solo vs AI: three difficulty levels, from casual to merciless Online Multiplayer: play friends anywhere with a quick invite Pass and Play: share a device across the table Timed Matches: add time limits to any game mode when you want the pressure on BUILT FOR PLAYERS, NOT ADVERTISERS No ads No paywalls No push notifications begging you to come back Just a clean board, a worthy opponent, and your next move. MULTIPLE PATHS TO VICTORY Push two pieces across to the far side. Capture enough of your opponent's army that they can't breach your walls. Or outscore them when the board thins out. Every game finds its own ending. Whether you have two minutes or twenty, Barrier gives you something to think about.
