WallBalls is a fast puzzle game about drawing a line in the right place at the right time. Balls bounce around the board. You swipe to build a wall. If a ball hits the wall before it is finished, the wall breaks. That is the whole game, and it gets hard quickly. TWO WAYS TO PLAY ISOLATE Trap every ball in a room of its own before the 30 second clock burns out. Each level adds a ball. DOMINATE Wall off the board piece by piece and leave the balls as little space as you can. You have five lives, and every broken wall costs one. FIVE POWER-UPS • Bolt: walls build fast • Sun: one more life • Magnet: drag the balls where you want them • Flame: burn one ball • Clock: stop time for 5 seconds NEW IN 2.0 • A complete redesign: a sharper board, pixel art power-ups and clearer menus • Built for current iPhone and iPad screens • No ads • English and Spanish Game Center leaderboards for both modes.
