The Cooperative Hint and Sync Game!
Work together as a team to complete a series of goals - without communicating what's in your hand.
Each player starts with a hand of 4 cards, each taking turns to play one number card onto one of the 4 piles in the middle of the table, and drawing up.
Whenever the top cards of all 4 piles conform to one of the 4 goals in play, that goal is removed from play and replaced.
The number of goals in any game depends on the number of players and the level of difficulty you attempt.
Can you make all piles purple or green? Every card lower than four? All cards add up to ten?
Run out of cards and the team loses, complete the required number of goals and the team is victorious!
There's only one way to win before the time runs out: play in cahoots!
