Double Up

After any paying round, in any game, you can gamble the win again — and again — until you collect, lose, or reach the win limit. Every Double Up returns exactly 100%: on average it neither adds to nor takes from your win. It only changes how much it swings.

Choosing one

Double Up is off until you pick a style. Choose it in the lobby's Settings → Double Up, or tap one of the tiles in the lobby's Double Ups group. The choice applies to every game. Set it back to None to switch it off.

Red or Black

One card is drawn from a full 52-card deck. Call its colour: 26 red, 26 black.

Call	Chance	Pays
Red or Black	1 in 2	2× the stake

Dice

Six buttons, one for each face of a die. Light between one and five of them, then roll: if a lit face comes up you win. The fewer faces you light, the bigger the pay — so you set the risk.

Faces lit	Chance	Pays
1	1 in 6	6×
2	2 in 6	3×
3	3 in 6	2×
4	4 in 6	1.5×
5	5 in 6	1.2×

Three faces (1, 2 and 3) are lit when you start — the same even-money call as Red or Black.

How it works

• Each step is your whole current win. Win and the new total is offered again; lose and the round pays nothing. Collect banks what you have at any point.
• It stays part of the round you won. Your history, stats and the leaderboard show the round's final result under the game you were playing — not a separate entry.
• The win limit ends a ladder. Once another win could go past the app-wide maximum win of 10,000, no further gamble is offered and the win is collected.
• The draw is made on the server, fresh for each gamble, and is never predictable from the round that came before it.
• A dropped connection loses nothing. Reload or come back later and the offer is waiting, at the stake it was on.
• Not offered during autoplay, when replaying history, or in Crash — Crash's round is shared with every other player and keeps running.
