How it plays
You are the keeper. The gem is yours to defend — and the boulders don't care how pretty your build is.
Drag blocks from your tray. Stack them, wedge them, layer them — any way you can to shield the gem. Blocks are limited, so every placement counts.
Hit the button and the barrage begins. Watch your structure absorb impact after impact — cracking, shifting, bending under the assault.
If the gem survives, you advance to a harder siege. If it shatters, you rebuild and go again. No timers. No energy bars. Just one more try.
The journey
Each realm holds a precious gem — and a harder siege waiting for it. From the quiet Plains to the shattered Ruins.
Your arsenal
Rubber deflects. Sandbags dead-stop. Barrels explode. Springs launch boulders back where they came from. Mastering them all is the key to a perfect defense.
The keeper's shop
Skilled defense earns coins — spend them before the next siege. No purchases, no pay-to-win. Everything is earned in the game.
Extra material in your tray — more to build with next round.
Restore your structure to full strength mid-siege.
Explodes on contact, destroying every boulder nearby.
Removes three boulders from the incoming barrage.
Every block you place gets double durability.
Absorbs one lethal hit and deflects the boulder away.
Mastery
Every level scores your defense. Three stars means the gem was never even touched.
The gem made it through the siege. That's all that matters… for now.
Survived with blocks to spare. A lean build is a smart build.
Not a single boulder reached the gem. The mark of a true keeper.
