Mattel UNO Zero

UNO Zero is a table top card game, where the goal is to score as low as possible (ideally zero points hence the name). Each player at the beginning has a set of six cards faced down in front of them. The grid consists of three columns and two rows. At the beginning each player can turn and reveal two of their cards. After that all players attempt to reveal all their face-down cards by drawing one card each turn from the discard or draw pile and exchanging them with one of their cards. Two cards of the same colour or the same number in one column are discarded. That way players can get rid of their points.

What's special about UNO zero is that the typical UNO action cards are part of this game. The reverse card changes the direction of the game. The draw two or draw 4 card makes players add more columns to their grid. And the skip card has the next player skip their turn.

That makes this game vey dynamic, surprising and fun.
Each round is different and you can get very lucky and have only two cards left at the very end, or unlucky and you still have 12 cards in front of you while another player finishes the game.

Once there is only one face-down card left in your grid you have to say UNO or you'll be punished to draw two more cards.
It's easy to learn and start, since the rules are quickly explained and the famous UNO action cards almost anybody already knows.
