How to Use
One player secretly puts some objects in a bag.
Another player guesses how many are inside and writes the number down.
The first player reveals the objects, then everyone counts them aloud together.
If someone guessed correctly, they get one point.
If nobody guessed right, the first player gets two points.
Take turns! The player with the most points wins.
