The building game with real physics. Build a castle, protect the treasure, survive the siege — and learn why structures stand or fall.

Themed castles across six escalating worlds — and a live, full-spectrum strain map that shows the physics at work as the siege pounds your walls.
Most block games are pure fantasy: stack anything, nothing ever falls. Re-Evolution runs a real structural physics engine, so kids build genuine engineering intuition — by playing.
Every block carries real load down to the ground. Towers topple, overhangs snap, weak materials crumble — for honest physical reasons, not scripted animations.
A full-spectrum strain map paints every block by how hard it's working — cool blue when relaxed, through green and orange to red at its limit — so kids can see exactly where a structure is overloaded before it fails.
After each siege the game explains why it held or fell — “bury the core,” “widen the base,” “too top-heavy” — turning a fun crash into a lesson.
Compression vs. tension, load paths, materials, center of gravity, redundancy — the foundations of engineering, absorbed through trial and triumph.
The first in a growing set of physics-powered learning games.
A toy-box where the fun is in the falling. Build something, then find out if it stands up to a beating.
Stack timber, masonry, concrete and steel under a gold-coin budget. Drag to lay walls, or tap Build Castle for an instant fort.
Set your golden core, then bury it deep. Everything is scored on whether the treasure survives.
Escalating waves pound your walls with real, physics-driven collapses — slow-mo, screen-shake, tumbling debris and dust.
Six levels from gentle to brutal. Earn stars, unlock the next castle, and keep your progress saved.
“Build vs. Smash”: one of you builds a fort, the other besieges it — then swap. The tougher castle wins.
Pull back, aim with the dotted arc, and release to fling a rock. The signature, tactile shot.
Lob a heavy boulder on a high arc for an area-clearing smash. Unlocks as you win.
A fast, flat, precise shot to snipe a buried core. The late-game power tool.
Every 5th shot is a powered-up blast, telegraphed with a gold trajectory. Line it up and let it rip.
