Nanashi is a simple but exciting strategy game with a nostalgic feel of gameplay similar to Ataxx, Reversi and Othello. The rules are simple: - you must own as many pieces as possible at the end of the game - you can jump one or two cells in either direction by selecting your piece and the target - targets one cell away will clone your piece into a new one - targets two cells away will make your piece jump without creating a new piece -- the original cell will be vacated if you jump. - after moving, all adjacent cells to your new piece will turn into your color - keep an eye on your timer - the game ends where there are no moves possible or when one player captures all the pieces of the opponent The game is available in three modes: - PLAYER vs ROBOT: play against your iPhone/iPad/iPod Touch in the role of a greedy AI - PLAYER vs PLAYER: two players can play against each other on the same device - PLAYER vs WORLD: play online against other players and try to reach the top of the leaderboard

Diagonal Duel against a level 0-100 computer, with two players on the same device, or in ranked online games! Diagonal Two Squared is a game similar to Connect Four but essentially with the board rotated at 45 degrees. This allows for play on two "sides" from the start instead of the original game, on which you only play only along the bottom. The app allows for two players to play on the same device, to select a level from 0 to 100 computer to play against, or to play against random opponents.
