6th Sense

In the trick-taking card game 6th Sense, you score by correctly predicting the number of tricks you'll take in a round.

The game lasts 4-6 rounds depending on the player count. The deck contains cards numbered 0-14 in five colors, and at the start of a round players are dealt a hand of 11-15 cards, then the top card of the deck is revealed to designate a trump suit. Each player then simultaneously chooses a card from their hand to predict the number of tricks they'll win this round, then places this card face down on the table.

In general, standard trick-taking rules apply: Someone leads a card, and other players must follow suit, if possible, with the highest trump or highest card of the suit lead winning the trick. That said, some cards have special effects when played:

When you play a 0, you can treat it as a 0 of that color, or you can remove the 0 and one previously played card from the current trick.

A trick with a 4 in it is won by the lowest card played instead of the highest; a second 4 cancels this effect.
