PairingSquare 5 - Simple Fun app for iPhone and iPad

The first piece played by each player must be placed in one of the boards corners. Each new piece played must be placed so that it touches at least one piece of the same color, with only corner-to-corner contact allowed—edges cannot touch. Edge-to-edge contact is allowed when two pieces of different players are involved.

To play, select your piece from your remaining deck and tap the board to place it. You can rotate, flip and drag your piece into place. Just tap the piece on the board for a handy way to rotate it into place. Pinch to zoom to get a better view.

You can form your strategy as you play. Do you play nice and find ways to weave between your opponents pieces, or deliberately try to corner them so they cant play in your space?
