I’m talking barebones. Tetris. Picross-like. Something that requires very little thought and is addictive.

For background, the reason I’m asking is because I recently read that researchers found that participants in a study on traumatic events saw that people who played tetris during their recovery had less traumatic response/activation over time? I’m currently going through a pretty traumatic time in life and am just looking for games that activate my lizard brain to forget about the hard times for a little while. Thanks in advance.
