Bround Tap a tile to turn it into a wall, so the ball can bounce off it and change direction. Get as many big balls as possible. The longer the game goes, the harder it gets. In Survival Mode, some tiles and walls will fall down. Avoid falling into a hole or going off the board. In Time Attack Mode, you have 60 seconds to collect big balls. Getting a big ball will give you bonus time. You will gain a longer bonus if you get multiple big balls within a few seconds.
