Focus...
I've been playing Shape Garden for over 5 years, and I think it really helps with focusing and grounding. The shapes are random, and seemingly infinite. Every game is a different experience with many color themes. It's my favorite game and is the best merge game I've ever played. It's so easy to play. It's great for kids too. It teaches cause and effect and shape recognition. 5 years, and nothing has come close to Shape Garden.
