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.

RUSH: THE ENDLESS RUN
The ball never stops: pick the part that gets it past the obstacle before it arrives. Every stage is faster. Play the Daily Rush (the same course for everyone), use powers like slow motion or the cannonball and collect balls. Every Monday, the world's top 10 and the top 3 in each country win coins and a badge for their avatar.

DAILY REWARD AND MISSIONS
Come back every day for your reward (7 days in a row, more coins each time) and complete 3 new missions with coin rewards.

300 LEVELS ACROSS 75 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. Plus lasers and mirrors, portals, springs, electromagnets, dynamite and upside-down gravity zones.

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