Gearworks

Build a machine from levers, gears, pulleys and ramps so its output force hits the exact mechanical advantage required.

How to play

Each level fixes a target mechanical advantage. Pick parts from the bank into the machine chain so the combined output ratio lands exactly on target — overshoot or undershoot and it fails. Solve a run of puzzles to finish, with the engine doing all the ratio math for you.

• Different parts multiply force by different ratios
• The chain's output must equal the target exactly
• Clear several puzzles in a row to complete a run

Controls

• Desktop: click parts in the bank to add them, click Lock In to check, Clear to reset, Next for the next puzzle
• Phone & tablet: tap parts and the action buttons — touch-friendly

Game modes

• Daily: one shared run of puzzles
• Practice: endless fresh chains

Tips & strategy

• Factor the target into the ratios available — work backward from it
• Watch the live multiplier update as you add each part
• Fewer mistakes score higher, so plan the chain before locking in
