Reiner Knizia's newest iPad game; ClusterMaster

Reiner Knizia's games work well on the iPad, as we've already seen with Through the Desert and Samurai. So ClusterMaster should turn out just as well.

This is a game that challenges you to fit coloured shapes onto a grid - you'll need to place the shapes efficiently while also building clusters of the same colours. The game features both timed quick games and as well as longer play modes. There are four modes in all.

It's the fourth time developers, Tribeflame, has partnered with Knizia, including the brilliant Through the Desert.
