A game for two people that will not make you bored. You can play with your friend in the crystal seven by two on one phone, making turns in turns. We recommend the rules of the game: Sit opposite each other and agree who will walk first Need to do so that you have more than your friend. You can even play yourself, you too will not be bored. This game is based on the game Othello (the same rules as there) We wish you good luck and victories!
