OtterBlast gameplay in the Lost Temple world on iPhone
Choosing a world in OtterBlast

Five worlds to play in.

Deep Space, Lost Temple, Liquid Glass, Castle Keep and Classic. Each has its own light-catching blocks that shift as you tilt your device, animated scenery, original music and a burst of themed effects on every clear.

Classic and Deep Space are free. One optional unlock opens every world, Rotate mode and all future worlds, shared with your whole family.

Made for families.

Built by a parent who got tired of their kid's favorite puzzle game showing ads. No ads, no timers, no coins, no pop-ups, no accounts and no data collection. Just a good game.
