A 3D printed version of the popular Triggle strategy board game by Fat Brain Toys. Players stretch rubber bands across pegs to form triangles and claim territory on the board. My parents sent me a photo of this game wanting one for my niece, but it was unavailable at the time — so I designed and printed my own version from scratch.
The game develops spatial reasoning, strategic planning, and critical thinking. Suitable for 2 players (optionally 3–4 with extra piece sets).

Place the board between players. Each player chooses a color and takes matching game pieces (markers). Prepare a supply of rubber bands. Decide who goes first (e.g. by drawing lots). Game is for 2 players (optionally 3–4).
On your turn, take one rubber band and stretch it across pegs on the board. The band must be taut and hooked securely around the pegs. Once placed, the band cannot be moved or removed.
Whenever your rubber band completes a triangle (a closed three-sided shape between pegs), you claim it by placing your marker inside. If you're observant, a single move can complete multiple triangles at once — giving you a big advantage.
Rubber bands may touch or cross other bands but cannot displace them. You cannot move your opponent's bands. Already claimed triangles cannot be taken over. Plan ahead — blocking your opponent is just as important as claiming territory.
The game ends when all possible triangles have been claimed or players run out of rubber bands. Count your claimed triangles — the player with the most wins. Tie = draw.
Spatial reasoning — visualizing shapes and positions on the board.
Strategic planning — setting up future moves while blocking opponents.
Critical thinking — evaluating which move yields the most triangles.
The large game board had significant warping issues during printing due to its size.
Added a brim and used adhesive (glue stick) on the print bed. This kept the board flat throughout the long 20+ hour print.
