Part of a game's challenge is simply learning to play it on any given platform. When Zuma came out, the hardest part was using the mouse, keyboard or game controller to rotate the frog shooting the marbles to exactly the right angle before firing. But what if you could just tap exactly where the marble was supposed to go? Would it still be fun, or would it be too easy? Riot Rings addresses this problem by taking the basic Zuma formula and adding so much to it that you forget that the issue was there in the first place.
