Instructables
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.

Step 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.

Step 2: Transfer to the plexi

I was satisfied with my placement from the cardboard/screws, so I used the cardboard as a template to mark holes on the plexiglass for drilling. If you were being more exact, you'd have to recreate the pattern on the plexiglass after testing with the cardboard and screws.

This is Great! I have also seen fully functionally Plinko boards at PrizeWheel.com.

I love this idea, have built one in the past but called it "Drinko"

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?

What did you use for the Plinko chips or coins or whatever they're called?
mazinbenny (author)  dci3 years ago
Head to your nearest Walgreens/CVS/Pharmacy with a 1-hour photo lab. (We had a really good friend who was a photo lab manager) We used the endcaps that they had in the rolls of paper they fed into their machines, and then just covered them with little disks of paper.
i have just a few days left to figure this out. first can i make a plinko game without a plexiglass? I dont want the game to be too heavy to transport. Not to mention if the game is tilted maybe plexiglass wont be needed. secondly i agree with the  pegboard to use instead of drilling holes but my  concern is will the pucks slide down smoothly to the slots below? Also where can i purchase real pucks for the game and  do u know the proper size of the puck?

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?

If you are mounting the board on the floor or whatnot, certainly you could go without the plexi.  We wore our board as a costume, so we needed the pucks to still fall without falling out of the board.  I don't have a good suggestion of what to use for pucks other than you can buy pre-cut wooden circles at most hobby stores, and then you can choose your peg spacing appropriately.  Maybe this would work better: www.ehow.com/how_5175617_make-plinko-carnival-game.html (it uses poker chips and peg board).  More info here too: mathdemos.gcsu.edu/mathdemos/plinko/

What was the final size of your plinko board?
mazinbenny (author)  Tonna4 years ago
I don't know off the top of my head, but I'm pretty sure I used a 20"x30" piece of plexi... maybe 24x36, but I'm thinking it was 20x30. And then the "bezel" around the peg area was likely 4-6" on the sides and 8-10" on the top. The bottom, to allow for the catch and numbers, was taller, likely 12-14".
i think that i like pickles to because they are tastey

Where did you get the Plinko logo and puck covers? Is there a file somewhere? And what is the "corner guard" material? Would I find it at Lowe's or Home Depot?
mazinbenny (author)  krisfisch065 years ago
I made the logos on the 'puter... I largely used the fonts from the Price is Right font archive (can't believe the things you find on the internet). Send me an email to amaziMYg1@umiPANTSch.edu (just remove my pants), and I'll attach the files for you. The corner guard stuff is the semi-flimsy plastic "L" shape that you sometimes see on the corners where two walls meet... meant to protect the corner from chipping or nicks when things bump the corner.

You could also easily use peg board instead of the 1/4" plywood, it would alleviate having to drill holes throughout the plywood and would make it lighter.
mazinbenny (author)  sjava5 years ago
I actually thought of this... but the problem is the hole pattern.... also, I had plywood lying around, so it was cheaper. The holes are in an offset pattern.
Agreed, but I think you could use the holes in the pegboard the same way. Since the holes in the pegboard are in a grid you could skip a row and still get the pyramid shape. ASCII art isn't my specialty, but if you look at the "image" below and follow the pattern where the "X" is the peg I think it might work. I've got some spare pegboard lying around so I'll have to give it a shot to see. ooooXoooXoooX ooooooooooooo ooXoooXoooXoo ooooooooooooo ooooXoooXoooX

Yeah, that would probably work. I think that's probably the first rule of DIY -- use what you have!
alinemarie6 years ago
Hello! maybe I overlook but I couldn't find what kind of materials you use to make Plinko. we want to make one real soon! As for puck or chip, what kind? Thank you
I know, this is not well explained and if you know the easiest way to make a plinko board, TYPE TO ME! -Thanks
mazinbenny (author)  alinemarie6 years ago
Thin plywood (1/4"), a sheet of plexiglass (a pre-cut rectangle meant for a window replacement), machine screws and nuts, and nylon spacers -- these need to match the thickness of your puck. For pucks, we went to the corner drug store/photo processing center and asked for the end caps from the photo paper rolls. Then we covered these end caps with little circles of paper. they were light, had the right sound, and perfect size.

I'm glad I found this page. I've been tasked with building a plinko board for our company holiday party (2.5 weeks away!) and this looks perfect. I think I was able to determine a parts list, just looking at the site here, but I'd really like to know what size/length machine screws you used and what the dimension of the plexiglass was. This is a really great idea! Thanks!
mazinbenny (author)  zacksof6 years ago
The plexi/lexan was a precut "window replacement"... and I'm pretty sure it was either 20z30 or 24x36. the machine screws were 3/8 and about 1 1/4 long -- trying to remember exactly, cause it was 1/4 ply, 1/2 nylon spacer, 1/4 (?) plexi (can't remember the thickness of hte plexi), then the lock nut. I lucked out cause whatever I guessed orginally happened to have the lock nuts flush when tightened down.
Great thanks. I was a little long in my measurements then. I was assuming 3/8" ply. How flexible was the 1/4" ply? Did you use a 4x4 sheet of plywood? I am concerned about it "holding up". Did the final piece flex at all? I appreciate your comments on this. This will be a lot of fun for the employees!
mazinbenny (author)  zacksof6 years ago
With the size of the quarter ply, it was fine... It was essentially rigid after the plexi was bolted to it... 3/8 would maybe be better if it was standalone. I was concerned with weight for wearing it as a costume. I had a 4x8 sheet that I just cut about a third off of.

apparently your whole family went with the price is right theme, you must have spent a long time on those costumes. and if your dog could read, he probably would be very sad.
mazinbenny (author)  Doctor What6 years ago
Yeah, our costume theme is always a big undertaking... luckily the two girls costumes were pretty easy. Plinko, the big wheel, and the dog took a while. I hope to write up instructables for the other costumes here soon...
i love your crazy ideas, just remember next time, parts list
mazinbenny (author)  Doctor What6 years ago
Yeah, I'm gonna add a parts list here soon. Check out some of my other costume themes here: http://www.flickr.com/photos/mazinbenny/sets/72157594345344175/ and http://www.flickr.com/photos/mazinbenny/sets/72157594345383135/
you go all out.
Doctor What6 years ago
u should add a parts list, and a cost list.
Doctor What6 years ago
i've always wanted a plinko board. still want to know how to make the wheel. you should pickle make an instructable on that too.
mazinbenny (author)  Doctor What6 years ago
I plan to create an instructable for the wheel too, just ran out of time. I'll do it eventually.
yay. please excuse the pickle comments, i had a couple of people who took over.
I like pickles....Do you like pickles? I like pickles.
