A named bonus roulette, not a colour bet.

Red Door
Roulette.

A roulette number can become a key to a second wheel. Evolution combines single-zero roulette with the Crazy Time bonus world — but only the right winning bet opens the door.

01

First a number. Then a key.

Red Door starts with an automatic roulette wheel and a presenter at a slot machine. Once betting closes, the slot display determines how many Keys are assigned to random numbers on the betting grid: from three to fifteen.

You need a straight-up bet — a chip on one exact number — to qualify for the bonus. If that number wins and holds a Key, the red door opens. A winning colour bet alone does not get you inside.

02

The second wheel changes the prize

Beyond the door is a 64-segment Crazy Time wheel. Its segments carry multipliers, which determine the bonus award. A Key can also receive a 2×–20× multiplier before the roulette result; when that number triggers the bonus, it increases the values on the bonus wheel.

The important sequence is bet, assigned Key, winning number, then bonus wheel. Seeing a Key on the grid is not itself a win.

03

The price of the extra possibility

An ordinary winning straight-up bet pays 19:1, compared with 35:1 on standard European roulette. The bonus opportunity comes with a different payout structure, even though the wheel still has one zero.

Use the rules displayed in your game to check how a bonus award is applied and which limits apply. Red Door and MONOPOLY Roulette share a family resemblance, but their bonus games are different.
