Jenga is a fun game to play, and easy to make for a large party. Keep it cheap and easy by using 2x4s and spray paint:

Materials:

(8) 8 ft lengths of 2x4
(1) Plastic drop cloth (if painting)
(1) Big sheet of thick paper (if painting with stencils)

Tools:

(1) Chop, or other, saw
(1) Belt, or other, sander
Spray Paint (if painting)

Step 1: Buy Some 2x4s

They’re pretty cheap and are easy to find. For a fairly tall game, I bought (8) 8 ft lengths for 69 pieces in total, or 23 layers of 3 pieces each and a game that starts around 3 ft tall.

Step 2: Cut and Sand

Cut each piece to 10.5" long with the method of your choice. I recommend a chop saw.

Sand at least the edges of each piece to remove large burrs.

Don't forget to play a test game!

Step 3: (Optional) Paint the Ends of Each Piece.

This goes pretty quickly if you lay them out standing tall, as in the first photo, and use spray paint. I recommend using a different color on each side.
