In The Mind players have a hand of cards which they need to collectively lay in the centre of the table forming a single discard pile in ascending order.
Seems simple, but the catch is that players cannot communicate with each other in any way. No twitches, no secret signals, no communication. Players must focus and synchronise their thinking and determine when the right time to play a card. As the game progress and players advance to higher levels players become more harmonised and the right time becomes easier to determine, at least that is the way the game is described.
This may sound a bit weird and pseudoscience but strangely it works, some of the time. The Mind is a quick-playing game, it is fun, it is tense and is super easy to play but hard to master.
