25 floors. One vault. Every door is a gamble —
stack your multiplier and extract by helicopter before you get caught.
Pick a door. Three are loot. One is a guard. How high do you dare to climb?
Rare server breaches slam flat bonuses straight onto your multiplier — ×5, ×25, ×100… up to a screen-shaking ×1000.
Survive all 25 floors and you reach the penthouse vault — one final pick that can triple everything you carried up.
Cash out any time after floor two. The chopper sweeps in, you leap from the window, the counter rolls your win.
One wrong door and it's over — sirens, shattered glass, multiplier gone. Greed is the real opponent.
Rookie keeps it friendly. Elite packs more guards per floor and pays brutally better — vault or death.
Every round is sealed by a server-seed hash before you bet. Verify any outcome yourself, cryptographically.
Set your stake, pick Rookie or Elite, and the heist begins at floor 25 — sirens already closing in.
Each floor: four doors, one guard. Every safe pick compounds your multiplier and unlocks the next floor.
Bank it with the helicopter — or push for the vault and triple it. Get caught and you leave with nothing.
Free demo credits, nothing to install. Right here, right now.
Before every round, the server commits to a secret seed and shows you its SHA-256 hash. Your client seed is mixed in, the floors are derived with HMAC-SHA256 — and when the round ends, the server seed is revealed so you can recompute every guard position yourself. The house can't move a guard after you bet. Math, not trust.
