Onirim is a solo/cooperative card game. You (and a partner) must work (together) against the game to gather the eight Door cards before the deck runs out; you can obtain those Door cards either by playing cards of the same color three turns in a row, or by discarding (under specific circumstances) one of your powerful Key cards. In both cases you will have to decide the best use of each card in your hand and carefully play around the Nightmares. Those cards are hidden in the deck and will trigger painful dilemmas when drawn.
Play time: 15 minutes
