Build little working machines in this free engineering puzzle. Learn through 12 crafted levels, then enjoy unique daily puzzles and unlimited play. Place gears, match the arrows and watch your solution turn.
Can I play more than once a day?
Yes. Daily mode gives everyone the same puzzle seed, refreshed at midnight UTC. Unlimited mode starts another round whenever you want. Word-based puzzles reuse a curated word and clue bank; puzzle content can recur.
Do I need an account?
No. Play immediately and keep boards in this browser. Connect Google to save up to 120 recent completed results across devices. In-progress collection boards stay on the device where you started them.
How do I challenge a friend?
Use Challenge a friend or Share your result. The link opens this game with the same puzzle seed. Your result text avoids revealing the solution. Collection results are personal activity records; the central Brisk daily six has its own server-checked ranking.
