In this instructable, I'll teach you how to create a "plinko" board for prize giveaways. Alternatively, you can use it as a tribute costume to the Price is Right, like I did! For those not in the know, Plinko is a game on the gameshow the Price is Right. A puck or chip is dropped into the top of a pegboard where it bounces around until finally coming to rest in a prize slot at the bottom of the board. Plinko is a play on the word pachinko.

Signing UpStep 1: Test Spacing
To begin, I just started with a piece of cardboard and a large handful of drywall screws. I wanted to test out the spacing of pegs so that the disks I had chosen would work well. I was using the plastic disks/donuts that came from the inside of a large paper roll at my neighborhood drug store / photo counter. They would have been in the trash otherwise, so I was helping out! They were about 2.5 inches in diameter, so I initially guessed at making the triangle at 3.5 inches (to allow for plenty of room in case of a bounce). I pushed the screws through the cardboard from the back and then tried dropping my puck down the board. It worked great! You'll have to adjust your spacing (and test) depending on what you choose as your puck. I used the triangle piece of paper as a template and just kept moving it. You could be more precise and make sure your pegs were colinear, but I decided just eyeballing it was enough.

I am looking to add touch sensitive led lights in the pegs though so they light up as the peg touches them. Anyone have any ideas on how to do this?
i am asking this because iam in charge of games for a school carnival and the carpenter needs specific detailed instructions on how to make the game and is wondering should he hold off until we purchase the pucks?
