No, not games that nurses play with each other, but actual games that might help with nursing.
For example: I love playing Minesweeper because it trains my brain to think in logical, deductive steps; Freecell, because it helps me see steps far in advance and helps with future planning/preparedness; and Tetris, because it helps with critical thinking and rapid decision making under increasing pressure.
Any others that people use/play to train their brains?
