Most projects here at Build Basic are brainstormed on a napkin or the back of a receipt, and then move quickly into the sketch, prep, and building stages. But when The Home Depot invited me to participate in a Lumber DIY Challenge, I found myself with a case of builder block–a close kin to writer’s block, which I experienced waaay too many times throughout my years in the Magazine industry. Somehow I found myself daydreaming of upcoming summer cookouts (i.e. reasons to procrastinate), which led me to thinking about how our barbecues typically turn into a “tournament of backyard games” among friends and family.


So, I thought, I already built a rustic DIY Baggo Game Set (which we LOVE), and just about every place I stop has a plan for Ladder Golf. So what game could we add to our “outdoor offerings” that would feel fresh and different? Enter my childhood love for Connect Four, and a strong urge to build a giant-sized version, complete it with holes, discs, and slots that empty when the game is over.


Which is all to say, my builder’s block was cured, the four-in-a-row game turned out waaay better than I thought it would, and we have a new reigning backyard favorite that’s perfect for all ages. Here’s how to build your own…

1. Layout the Holes


Using the cut list above, cut the plywood pieces to size. (Tip: Use my easy DIY Plywood Cutting Tutorial). Sandwich the two pieces of ¼-inch plywood together. Place the plywood pieces on support blocks. Clamp the plywood and support blocks firmly to the work surface. Mark a grid on the plywood to designate the center of each circular cutout using my Building Plans HERE.

2. Create the Pilot Holes


Because hole saws can wander a bit until the drill bit bites into the wood, drill pilot holes at each crosshair. Choose a drill bit with a sharp point, like a brad point drill bit.

3. Cut the Holes and Discs


Using a drill/driver fitted with a 4-inch hole saw, drill the holes. To see my tips on how to use this tool, see my tutorial HERE. Tip: Allow time between cuts for the drill motor to cool, and keep a second battery charging, as this part of the process can run through a battery’s power quickly.

Lastly, cut the discs from a separate piece of ½-inch plywood using a 5-inch hole saw attachment. The interior cut out of this size hole saw is just under 5 inches (because you lose the thickness of the blade), which allows the discs to pass freely through the 5 inch spacing between dowels later. Likewise, the thickness of ½-inch allows the discs to “stack” on top of one another inside the slot.

4. Join the Panels


Place the panels back-to-back. Apply glue to two ½” x 2 boards. Position the boards between the plywood panels flush with their side edges. Clamp the parts together. Nail through the plywood and into each board from both sides using 5/8-inch nails to join the panels.

5. Position the Dowels


To create the slots for the discs to fall into, slide ½” x ½” square dowels between the plywood panels, centered between the holes, spaced 5 inches apart. See the Building Plans above for reference. Nail through the plywood panels and into the dowels from both sides to hold them in place.

6. Build the Legs


Using a pocket hole jig, drill pocket holes in one end of each horizontal 1 x 3. Apply wood glue to the end of the board. Clamp the board against the edge of the 36-inch Stand, flush with its bottom edge. Screw through the pilot holes using 1¼-inch pocket hole screws. Attach a second board on the opposite side of the Stand. Repeat to create the second leg. Hold a 1 x 3 angled from the tip of the horizontal piece to a height of 11 inches on the Stand. Mark the angle at each end, and then miter the pieces to size. Apply glue to the mitered ends, and then toenail them into place using 1¼-inch nails. See the Building Plans for reference.

7. Secure the Legs


Apply wood glue to the sides of the assembled plywood panels. Position the legs on edge against the panels. Make sure the pocket holes on the legs are facing inward. Raise the plywood with a scrap 1x block underneath to center it on the width of the leg. Nail through the leg and into the ½” x 2 board with 1¼-inch nails.

8. Add a Board to Catch the Discs


To hold the discs in the frame during play, covered the gap at the base of the plywood panels with a hinged 1 x 2. Position and secure the hinges along the outer edges of the plywood panel so that the screws sink firmly into the ½” x 2 boards as well as the edge of the 1 x 2.

9. Add a Magnetic Catch


With the hinged 1 x 2 in the closed position, flip the assembly over. Attach magnetic catches near the ends of the 1 x 2 and plywood panels, as shown.

10. Build the Tray


To assemble the tray’s floor, first drill pocket holes along the adjoining edges of the 1 x 3 floor boards. Apply glue between the boards, and then use 1¼-inch pocket-hole screws to secure them in place. Using a nail gun, shoot 1¼-inch nails through the 1 x 3 tray sides and into the outer edges of the floor boards. Cap the ends of the tray with the 6½-inch-long 1 x 3’s. Nail through the boards, and into the ends of the side and floor boards using 1¼ inch nails.

UPDATE: Some reader have said this magnetic catch doesn’t quite hold the weight of their discs. A screen door hook or shutter magnet is a good alternative (Thank you to Steve for the suggestion!).

11. Secure the Tray


Lastly; mark a height of 5 inches on the inside of each leg. Raise the tray until its top edge reaches the line, and then clamp it in place. Repeat on the opposite side. Nail through the legs and into the tray to hold it in place. Now grab the game pieces and an opponent and battle to get four discs in a row horizontally, vertically, or on a diagonal. When the game is complete, flip open the hinged 1 x 3 to release to discs and play again!

  1. pshaver36

    Should the discs be 1/4 in thickness being that there is only 1/2 inch spacers between the 2 game boards?

  2. Lee

    First off, thanks for the post. But I have a few issues and asking if you could address.

    1. The magnetic cabinet holders do not hold the weight of dropping the discs. (I attached 5 and still no luck)

    2. All the dimension that are incorrect. True measurements are needed. 2’x4′ panels at Home Depot are actually 23.78″ and 47.78″ respectively. (This is for all pieces)

    3. Using 1/2″ thickness for the discs leave zero room for error. Adding paint, filling in holes with wood filler. I would suggest 1/4″ thickness for discs.

    Just a few thoughts for someone who wants to do this project.

      Welcome to the line of people experiencing this – I had hoped the author would have revised this project/

      Welcome to the line of people addressing this error in the plans. I had hoped the author would have revised it.

      1. Use a screen door hook instead of magnets

      2. Reduce the diameter of the disks by ¼” or more but you have probably invested a tidy sum in the recommended hole saws that are too large in the first place for a nominal 2′ x 4′ panel.

      3. Also commented on – do not fill the holes – leave them alone. As you point out, go to ¼” sheet and space the distance as 5/16 inch or ⅜”. The plans erred in spacing the same distance as the thickness. More significantly, cutting through ¼” material instead of ½” is far more workable, particularly if trying to use a cordless drill. A corded drill is a far better choice.

    3. Anonymous

      Everyone who builds knows all the measurements that are given such as 2×4 or 1×3 is always a 1/4 inch short.

  3. BC Olsen

    If the game pieces are 5″ in diameter, the holes in each column should also be 5″ apart. The plans say 4 3/4″. This dimension would cause the stack of game pieces to not be centered in the holes.

  4. Adam


    Why have you made ​​your game with only 5 rows, unlike the original game with 6 rows?

    1. Anonymous

      Adam – if I may chime in, I was curiouis and if you Google Four In a Row, you’ get as many as 7. This one came from Depot and at this size it fits on a 2′ x 4′ sheet so it lends itself to what they sell. I cut mine as 3″ and 4″ but it is a matter of convenience to my observations. Just my two cewwnyts worth.

    Thank you for these instructions. I have been looking for directions like this for a while. I did make some modifications. a real Connect Four game has 42 holes (7across , 6 down) so I just added an extra 4.75 to the height. 4 and 5 inch hole saws are pricey, I guess I will have to make several games. The diagrams were very helpful.
    Thanks again.
