Certainly, here are some DIY Halloween game ideas that you can create with household items:

Ghost Bowling: Stack up empty toilet paper rolls painted as ghosts and use a small ball to bowl them over, aiming for a fun and easy homemade bowling game.

Spider Web Walking: Create a floor maze using painter's tape in a spider web pattern, challenging kids to walk along the lines without touching the "web."

Pumpkin Tic-Tac-Toe: Draw a tic-tac-toe grid on a cloth or paper and use mini pumpkins and gourds painted as Xs and Os for a festive twist on the classic game.

Halloween Memory Game: Make pairs of Halloween-themed cards using printed images or drawings, then flip them face down for kids to find matching pairs.

Witch Hat Ring Toss: Paint or decorate paper plates to resemble witch hats and use glow sticks or rings to toss onto the pointed hats for a fun and easy ring toss game.

Pin the Spider on the Web: Draw a spider web on a large sheet of paper or cloth and blindfold kids to pin paper spiders onto the web, similar to Pin the Tail on the Donkey.

Candy Corn Count: Fill a jar with candy corn and have kids guess how many are inside, with the closest guess winning a prize.

Pumpkin Golf: Use carved-out pumpkins as holes and a plastic golf club to guide a ball into the pumpkins for an entertaining DIY golf game.
