Yantra: Contraption Puzzle — a Free Physics Puzzle Game in Your Browser

Yantra is a free, no-download contraption puzzle. Every level is a broken machine: pipes, ramps, gears and gates that almost work. Drag the loose parts into place, rotate them, then press Start and watch the balls roll through your fix.

70 levels across 5 worlds

Each world adds new parts and new ideas. Deliver enough balls with few spills to earn up to three stars, then replay earlier levels to improve. A new Daily puzzle gives you one more machine to fix every day.

How to play

Drag a part from the toolbox onto the machine, rotate it, and press Start. Works with a mouse on desktop and touch on tablets, in landscape.
