COGWORKS IS YOUR POCKET WORKSHOP
Build a machine that actually works. Place ramps, seesaws, fans, springs, belts, dominoes, trampolines, balloons and more to send the ball into the goal. Run your invention, watch the physics play out, and fine-tune every piece until it all clicks.
Every puzzle has many solutions. Take the simple route or engineer a spectacular chain reaction. Solve with fewer parts, then tune the machine for speed.
FAIR WORLDWIDE LEADERBOARDS
Every solve ranks worldwide: first by how few parts you used, then by your time. Open any puzzle to see the parts distribution and the top runs from builders everywhere, or climb the global board by how many puzzles you have solved. The physics is deterministic, so the same machine behaves the same on every run and results stay fair.
A FRESH CHALLENGE DAILY
Come back each day for one certified contraption challenge, the same for every builder, and keep your streak alive.
MANY HANDCRAFTED PUZZLES
A growing library of handcrafted puzzles, from gentle first builds to devious multi-stage machines, with new ones added over time. Learn what every part does from your workshop mouse, then build it your way.
A CALM, PREMIUM BUILD
No forced ads and no interruptions. Clear controls, undo and redo, and a reduced-motion option keep you in the flow of your next big idea.
