Qubotron, an UNEXPECTEDLY FUN, and Simple Game.

Qubotron reminds me of 3D tetris. You need to place the blocks in the best possible position in order to get the best scores. There are 3 modes in normal game play and also a zen mode. The 3 modes have varying levels of difficulty and its actually quite fun. Zen mode is definitely what you should play i f you want as little stress as possible. I think this game could be an enjoyable time killer and I had fun playing it.
