Attach 3 to 6 small buckets to a board about 6" apart. The player tries to toss a ball into the buckets in order, from the closest to the farthest away.

Ping pong balls are often used for this game as they bounce a lot so are harder to get in the bucket. If you want to make the game easier, you can use bean bags or soft balls.

Variation:

3-2-1 Blastoff: Paint the board to look like a rocket and use red, white, and blue buckets.
