How a round works

  1. Back it

    Bet on how long the tower stands, on which pull kills it, or both.

  2. The claw pulls

    Every block it survives lifts your multiplier — and the odds of a collapse.

  3. Get out in time

    Cash out after any pull. Still in when it topples and the stake is gone.

What is in it

Full rules and detail5 steps

A betting take on Jenga. A tower of 48 blocks stands on a steel plate under one hard lamp, and an automated claw pulls a block out of the lower courses every turn and sets it on top — so the tower gets taller while the part holding it up gets thinner. The chance the next pull brings it down is printed on a gauge before you commit to it: 4% on the first pull, three and a half points more on every pull after. There are two bets on the same tower. THE CLIMB is a cash-out ladder — every pull it survives lifts your multiplier and you take the money whenever you like, up to 484.85× at pull 16. THE TUMBLE is a separate bet on which pull finally brings it down, in four bands. Both return exactly 97%, every rung and every band, and the whole tower is sealed to a blockchain block before the claw moves. You start with a Rs 50,000 demo bankroll.

How to play

  1. Back the climb, back a tumble band, or both. The climb is the cash-out ladder; the tumble bands are 1–3, 4–6, 7–9 and 10+ pulls, paying 4.62× down to 2.72×.
  2. Every pull that holds opens the same eight-second window: ride on now, cash out, or do nothing and the claw takes the next block by itself.
  3. Watch the collapse factor. It is the chance THIS pull brings the tower down, it is on screen before every pull, and it climbs from 4% to a certainty by pull 29.
  4. Cash out at the end of any pull, at whatever the ladder is showing. Set 'auto cash out' to a pull before the claw starts and the climb comes off the board there by itself, watching or not.
  5. The tower always falls. Your tumble band settles on the pull it goes down on, whatever you did with the climb — so a player who got out at pull three still has something riding on how far it gets.
