Bank-A-Shot
Make a bank-a-shot game using an easel, laundry basket and wiffle-type balls. Stand the easel up and place the laundry basket in front of the easel. The object of the game is to bounce the wiffle-ball off the easel into the laundry basket. Give each player three tries to bounce the balls off the easel into the basket. If they make a ball, they receive a prize.
Hoop Prizes
Scatter large prizes all over the party area and mark a standing line about 10 feet from the prizes. Adjust the line further away or closer to the prizes depending on the ages of the players. The object of the game is for players to try to toss a hula hoop over the prize they want. They must completely surround the prize with the hula hoop in order to win it.
Guess Your Weight
Place a bathroom scale on the floor or in the party booth and tell players they have to guess their own weight. If they are within 20 pounds, they receive a small prize, within 15 pounds, a medium prize, and within 10 pounds, a large prize.
Lucky Leis
Fill a box with plastic leis and pull several leis out. Spray those leis with an invisible glow-in-the-dark spray and allow time to dry. Mix those leis with the ones in the box. Setup a black light and have each player select a lei from the box. If the player's lei glows in the black light, he wins a prize. You can adjust the amount of leis you spray depending on the number of prizes you want to award.
Ping-Pong Ball Toss
Set up several rows of goldfish bowls and give each player a bucket of ping-pong balls to try to toss in the bowls. Color the rim of each goldfish bowl to determine the type of prize the player wins when she makes a ball. Another idea is to award a small goldfish in a plastic bag with air at the top to each player who makes a ball in the bowl. Goldfish are available at many pet supply stores and some retail stores.
