Can you solve today's impossible challenge?
Get the egg across the canyon into the nest
Today's impossible physics challenge
A new impossible physics challenge every day, plus 72 puzzles in six workshops. Get an egg across a canyon, guide 100 people out of a falling tower, build a car that climbs a wall, bounce balls into buckets, topple crates and herd sheep. The simulation checks your solution, keeps a replay and gives stars for lean designs.
Solve each physics challenge. Place the parts you are given, press play to run the simulation, and adjust your design until it works.
