pop out before it pops.

One bubble. Everyone watches the same one. It grows ×2, ×10, ×50 and pops at a point set by a block hash nobody controls. Not us, not you, not the guy next to you.

LAST POPS
01

Your rides

Kept in this browser. Points refill to 1,000 every day.

Board a round to start. Five seconds to get in, then it flies.
02

How a round works

Thirty seconds, same clock for everyone.

0–5s · BOARD

Get in

Pick a stake and, if you want, an auto pop-out. Boarding shuts at the fifth second.

5s · SEAL

The chain picks

The pop point is the hash of the first Robinhood Chain block after boarding shuts. Blocks land every ~0.1s, and nobody knows that hash in advance.

6s+ · FLY

Pop out

The bubble grows faster and faster: ×2 at 5s, ×10 at 13s, ×100 at 21s. Pop out and you keep stake × that number. Wait too long and it's gone.

03

Check any round

Every pop is public math on a public block.

r = first 52 bits of block hash ÷ 252
pop = max(1, ⌊99 ÷ (1 − r)⌋ ÷ 100), capped at ×100
chance to reach ×X = 0.99 ÷ X
Pick any round from the strip above, or paste its number.
04
