EVFive is a "gobang" game, called Wuziqi in China. White and black sides play on a 15-by-15 board in turn. The side that puts five buttons in a continuous line in any direction wins. EVFive features the ability to play against the computer or your friends, and has restart, stop, and undo functions.
