A multiplier scales a win several times over: 2x, 10x, 100x. It sounds simple, yet in different slots it lives in different places, on a Wild, on a chain counter or on a separate reel. That decides how often it actually fires and how much of the cap it supplies.
In AvatarUX’s PopRocks (7 April 2020) the game itself keeps the count: every win pops symbols, the grid grows, and each batch of seven popped symbols in the vault adds 1x. The cap is 72,188x with very high volatility. In BGaming’s Alien Fruits (13 April 2023) a teleport carries multipliers from 2x to 100x, and in the bonus they apply to the total of the whole sequence, not to the first win. The longer the refill chain, the bigger the base the final coefficient works on. The card lists 95.97% RTP and a 15,000x cap.
The multiplier as a choice
Quickspin’s Eastern Emeralds (10 July 2018) offers a trade: after three bonus symbols you take 6, 9, 12 or 15 free spins, and the fewer there are, the higher the multipliers. The best line pays just 7.5 bets, so all the interest sits in multipliers, and the studio called 1,680x its highest ever. Evoplay’s Curse of the Pharaoh (September 2021) lets you choose among three modes, from 18 spins with a multiplier up to 10x to six spins with a far higher one. At most you can reach 2,803x.
In Red Tiger’s Jingle Ways Megaways (2 December 2021) a Mega Wild covers a whole reel and carries a ways multiplier of up to 7x. It can land only on the four middle reels, up to four at once. Kalamba Games’ Blazing Bull (21 April 2020) makes Wilds 2x in its silver free spins, with 97.42% RTP at very high volatility.
The simplest case is Pragmatic Play’s Gates of Aztec (31 January 2023), where multipliers sit on the board from 2x to 500x. In Big Time Gaming’s Millionaire Megaways (2022) each reaction in free spins raises the multiplier by one, with a 72,310x cap.
To avoid being fooled, check what the multiplier acts on, a single win, a chain or a whole round, and whether it resets. The bonus rounds that carry these multipliers are explained in the free spins article.
