Howling Moon Software has released SribBall, an arcade and puzzle game for the iPhone and iPod touch. This release is based on the Mac game that shares the same name. Users change the direction that the balls fall by tilting the iPhone. When four balls of the same color touch, they pop, allowing more to pour down from the top.

Gamers are challenged to react swiftly to strategically tap out balls for combination points. The colorful graphics are all hand drawn, showing the different balls tumble and fall into place. ScribBall is available from iTunes for $4.
