## What is Contraptix?

Place ramps, gears, magnets, balloons and rockets, press Play and watch every piece set off the next one. Contraptix is a physics puzzle game where every level is an unfinished machine: you add the missing parts and real physics decides whether it works.

212 LEVELS ACROSS 53 STAGES
Start with simple chain reactions and finish with huge machines full of belts, pulleys, pipes, switches and timers. Every stage introduces a new part.

A THOUSAND WAYS TO SOLVE IT
There's no single answer. There's always a spare part on purpose: choosing well is part of the puzzle. Use few parts and be quick to earn all three stars.

PARTS WITH PERSONALITY
Bouncing balls, gears passing on their spin, fans, scissors that cut ropes, boxing gloves, light bulbs, cannons, trampolines and a mouse running in its wheel.

DAILY CHALLENGE
A new puzzle every day. Fewest parts wins; on a tie, the fastest. Compete on the world and country leaderboards.

FREE MODE
Build whatever you like with every part you've discovered.

PLAY YOUR WAY
No sign-up, plays offline. Link Google or Apple whenever you like and your progress follows you to any phone. Available in 9 languages.
