DIY Giant Jenga Game from 2x4s

If you’ve never played Giant Jenga you don’t know what you’re missing. It’s such a fun but easy game to play with two people, or with many at a backyard party. Today I’ll show you how easy it is to make your own DIY Giant Jenga Game.

Ok, to be honest I hadn’t played it until last summer, but it’s so much fun.

My dear friend called me recently and asked me if I’d help her make some games for her husband’s surprise party. Of course I said yes. I’ve been wanting to make for myself anyway.

That very hot weekend we not only made this Giant Jenga game and we also built a set of DIY Cornhole Boards. It was a very fun weekend with my very dear friend; but we were both whooped when it was over.

This game is the perfect project for this month’s At Home DIY Challenge because the theme was $20 DIY Projects. You can find the link to all the other great projects at the bottom of the post.

Giant Jenga Game Cut List

  • 54 sections of 2×4 cut to 10-1/2″

That’s it, that’s all you need 😀

Mathematically you’ll get 9 giant jenga pieces from each 2×4 and that equals 6 2×4 boards. But you’ll likely have some areas you want to cut around, such as knots or gouged areas. That’s why we bought 7.

Step 1: Cut all your pieces

Set up your miter saw and cut all your pieces to 10-1/2″. Are you wondering why jenga pieces are 10-1/2″?

The 2x4s are cut to 10-1/2″ because three 2x4s side-by-side measures 10-1/2″. (who’s idea was it to actually make them smaller than the name? #truthinmarketing?)

It’s not super important that your lengths be exact, but if you’re OCD like me I’ll show you how to how you make them exact.

On your miter saw look at your fence (that’s the vertical part at the back. The have holes in them and, they usually slide out to adjust for varying cut lengths.

Anyway, find a piece of scrap that has a square end and attach it to the fence from the back.

Make sure you use screws that are long enough to pass through the metal and into the wood. But not long enough to stick out too far. Alternatively you could also use a clamp.

When you’re ready to cut the pieces measure and mark the 2×4 at 10-1/2″. Place the 2×4 on the miter saw and against the wood block. Adjust the fence of the miter saw until the non-moving saw blade lines up with the pencil mark.

You can practice this step on scraps and make necessary adjustments. It’s always best to be a bit longer and cut off a bit more. Lock the fence into place and proceed to cut the rest of your pieces.

Step 2: Sand the 2×4 Giant Jenga Pieces.

I was blessed that my brother “lent me” his bench sander. He said he doesn’t really use it so I can keep it at our house until he does 😀 It’s 20 years old and it’s a beast. I can’t wait to use it on more projects.

Working together with my friend and my hubby we started with 60 Grit on the bench sander.

Then those were passed along to the other two and they got another pass with 120 Grit sandpaper.

We played a little sander musical chairs.

I’m so glad that my daughter and her hubby bought me the orbital sander for Christmas. But using the palm sander worked just fine as well.

Now some people will tell you that you don’t need to sand. And maybe you don’t but if you’re using construction lumber you’ll usually see milling marks and such that would make it very hard to play.

Sanding your 54 Giant Jenga game pieces will make them slide out from between other pieces so much easier.

Almost done! Thank God for ear plugs and dust masks. We had the shop vac hooked up to the bench sander and that knocked down a lot of the sanding dust. But that just adds to the noise. So wear ear protection please.

I’m not going to say this was a fast project, even I was surprised at how long it took us to sand. But for just $20 in lumber and a little time sanding the pieces are smooth and the game will be fun.

You can buy pre-made sets online as well.

If you want a hardwood set, those will cost you 5-7 times what we made this DIY Giant Jenga set for.

My friend lives in Southern CA and we were so pooped when we finally finished the two-day game making marathon that I forgot to take finished photos.

Ok, I’ll be honest, we were rushing to go enjoy a little happy hour libations before she left the next morning. She was sweet enough to snap some photos of the rest of the process.

Step 3: Adding a protective coat

If you wish you can add a light coat of polycrylic. Some people like to stain theirs. And still others paint the ends in fun colors.

A light coat works best and you’ll want to make sure there’s no puddling. Or the paper will stick to giant jenga pieces and be hard to get off.

2x4s spread out on work table getting a coat of clear poly.

Let the dry fully. If the pieces feel like they’ll stick together instead of sliding easily you might need to do a light sand with a 220 Grit sandpaper.

Step 4: How to Play Giant Jenga

To stack up your Giant Jenga game lay 3 pieces side by side. On top of those stack 3 more across the first row. Continue that process until you have 18 rows of 2 pieces each.

Stack them as straight as you can while stacking. If your tower leans too much your game may not last very long. But that might be a good strategy to try.

Each person takes a turn pushing/pulling one piece out from somewhere in the stack and sets it on the top. Those pieces are stacked in the same manner as the initial stack.

Watch your toes, and little kids, around this game. It smarts to have a game piece hit your foot.

FYI - 2×4 is reference to the size the boards are cut to when harvested. They loose up to ¼ inch on each face as they're processed and dried.

Yes, but they are still commonly referred to as 2x4's. All instructions are adjusted for the actual measurements of the lumber I purchased. However, caution should be taken by anyone building anything off plans from the internet because the lumber industry continues to adjust downward the sizes of construction lumber.

When we lived in NC, we used to go to a brewery that had one of these for the kids to play with. Our daughter loved it! I'd always meant to build one but totally forgot about it. Thank you for the reminder! Pinning it so I don't forget again.
