Gamble mechanics: how the algorithm works
The Gamble (or Double Feature) feature in slots is an additional risk round that is activated after winning. Despite the simplicity of the interface - choosing a map, color or step on the stairs - behind this mechanics is a clearly defined algorithm based on a random number generator (RNG).
1. How Gamble works
After the player wins, the slot offers a "double" option. At this stage, a separate process is started that is not related to the previous rotation. The random number generator generates a risk game result regardless of the combination on the reels. The probability is most often fixed - 50% for choosing red/black and about 25% when guessing the suit of the card.
2. Result selection algorithm
1. Initiation. The player presses the Gamble button.
2. Generating a random number. The RNG generates a value from a predetermined range.
3. Matching with conditions. For example, 0-49 corresponds to "red," 50-99 - "black."
4. Displays the outcome. The player is shown a map or step on the ladder that matches the result.
5. Continuation or completion. If successful, you can risk it again, if you lose, the win burns out.
3. Impact of the algorithm on RTP
It is important to understand that the RTP slot is specified without taking into account Gamble, since this function has its own independent mathematical calculation. In most cases, long-term RTP in a risk game is about 100% when guessing color and lower when guessing suit. In practice, the casino may limit the number of consecutive attempts (e.g., to 5), which reduces the overall benefit of the player.
4. Integrity control
RNG certification. The algorithm is audited by independent laboratories (GLI, iTech Labs, eCOGRA).
Transparency of mechanics. The slot rules specify the probability of winning and the doubling limits.
Regulation. In some jurisdictions, Gamble is restricted or disabled to protect players.
5. Implementation features of different providers
Novomatic. Classic "guess the color/suit" model. Simple but entirely RNG-based.
EGT. Card slots where you can double up to five times in a row.
Play’n GO. Sometimes variability is added - the choice between several maps, but the algorithm remains the same.
Amatic. Implements a risk ladder, where the RNG determines whether the player will rise to a new level.
6. Algorithm limitations
The maximum amount of doubling is fixed by the rules of the casino.
The number of consecutive doubles is limited (3-5 times depending on the slot).
When a limit or a large win is reached, the Gamble function can be automatically blocked.
Result
The mechanics of Gamble are extremely simple: the random number generator determines the result with a predetermined probability. Interface - maps or stairs - only the visual design of the algorithm. The integrity of the function is ensured by certified RNG and regulatory oversight. For the Gamble player, it remains a choice between maintaining a guaranteed win and the risk of completely losing it for the sake of instant doubling.
