Count to 20, taking turns giving a number. But be careful, at each round a constraint is added and it will be necessary to replace one number by another, by a gesture or by a word.
When a player takes more than 3 seconds to play, forgets a constraint or enters the wrong number, it is counted as an error. The round of counting ends immediately and a Gem is taken from the reserve and placed in the box. Then, the player who made the error starts a new counting round, starting from “1”.
The game can be ended in two ways:
1. All Constraint cards are turned over. The players have won the game! They can continue by placing 4 new Constraint cards on the table and start a new round of counting.
2. There are no more gems on the table. The game ends when the last gem is returned to the box. You have to try again!
What we liked is that the game evolves throughout the game
