Germs are invading your tiles! Only Altro WhiteRocks can help! Blast your rocks at the breeding germs before its too late! Cover the majority of the tile surface with WhiteRocks to proceed to the next level. But beware - you only have a limited number of rocks to fire and your time amount will reduce on every level, so you'd better be strategic about where and when you fire your rocks!

细菌正入侵您的瓷砖。此刻只有Altro WhiteRocks能杀死细菌。你的任务是将Altro WhiteRocks发射到细菌上防止其繁殖泛滥。需要将大部分的瓷砖表面都用WhiteRocks覆盖住。但是注意-玩家只有有限数量的WhiteRocks，而且时间也会逐级递减，所以玩家要把握好发射的时机。
