This game is crazy addictive, it's 400 Microsoft points ($5). It's a kind of like a blend between Tetris and Lumines. The object is to make quads that cover at least a 3 x 3 section of the grid. These quads affect the music playing, each time the beat line passes over a quad it adds a sound to the music. Chime's really hard to explain so I'll add a video to the end of this, lol.
But in addition to being a really good game Chime also is for a good cause. A minimum of 60 percent of the purchase price is donated to the OneBigGame charity initiative. OneBigGame always aims to donate a minimum of 80% of all donations to its charity partners Save the Children and Starlight Children's foundation.
And this is my favorite song to play in Chime,
