Opal Fruits slot
Opal Fruits is a Big Time Gaming slot launched in May 2019. Six reels run down the middle of the screen, framed by a horizontal reel above and another below, for 5,625 ways to win. The studio called its engine Triple Reaction, because a win is refilled from three directions at once, and in the free spins every one of those refills nudges a multiplier upwards with no ceiling.

How Opal Fruits plays
The paying symbols are pieces of fruit: pears, plums and watermelons, with bunches of grapes at the top of the paytable. Instead of fixed lines, the game counts 5,625 ways across its six vertical reels, and the strips above and below the main area add symbols of their own while sliding sideways.
In the base game, the main reels can carry a 3x multiplier wild, which triples any win it helps to form. The scatters are gold letters, and the bonus asks for all four of them on screen at once to spell the word FREE. After a win the paying symbols disappear, and the gaps close from above and from the side before the grid is checked again.
Opal Fruits: 6 reels, plus a horizontal reel above and one below; 5,625 ways. Wins drop away and new symbols fall in, so one spin can pay more than once.
Triple Reaction
Big Time Gaming built Opal Fruits around a refill system that moves in three directions. On the six main reels, replacements fall from the top, while the two horizontal strips push new symbols in from the side. Every refill is checked for wins, and the sequence keeps going as long as new combinations appear. Nothing has to be chosen or held: the chain plays out by itself, and the spin only ends once a refill fails to create a new combination.
The free spins and the Win Multiplier
Spelling FREE starts 10 free spins with a Win Multiplier of 1x. Each reaction raises it by one, with no cap on how high it can go. The round also pays for progress: every time the multiplier reaches a multiple of 10, five spins are added.
Extra scatters during the free spins
The gold letters do more than open the round. Big Time Gaming’s rules tie extra scatters to the Win Multiplier rather than to the spin count: an extra scatter gives the multiplier a 5x boost, and every additional scatter after that one adds a further 10x. Extra spins themselves come only from the multiplier passing 10x, 20x, 30x and each later multiple of 10.
Opal Fruits compared with Extra Chilli and Bonanza Megaways
When it announced Opal Fruits, the studio named two of its own Megaways games as reference points. Bonanza Megaways came first, in December 2016, with up to 117,649 ways and 12 free spins for the G-O-L-D scatters. Extra Chilli followed in April 2018 on the same scale of ways and let you gamble its spin award for up to 24. Opal Fruits keeps the climbing multiplier of both but trades the Megaways reels for a fixed 5,625 ways and refills from the side as well as from above.
| Game | Released | Grid and lines | Free spins |
|---|---|---|---|
| Bonanza Megaways | 7 December 2016 | 6 reels, up to 117,649 ways | 12 spins for G-O-L-D scatters; multiplier rises with each reaction |
| Extra Chilli | April 2018 | Megaways, up to 117,649 ways | Spin award can be gambled for up to 24; multiplier with no cap |
| Opal Fruits | May 2019 | 6 reels plus two horizontal reels, 5,625 ways | 10 spins; 5 more at each multiple of 10 on the multiplier |

Frequently asked questions
Which symbol pays the most in the Opal Fruits slot?
The grapes. They head a short fruit paytable that also includes watermelons, plums and pears, and six of them in a combination gives the top regular payout. A 3x multiplier wild on the main reels can lift a grapes win further in the base game.
How many free spins can you get in the Opal Fruits game?
The round opens with 10, and there is no fixed limit after that. Five more are added every time the Win Multiplier reaches another multiple of 10, so the total depends on how far the multiplier climbs. Extra scatters raise the multiplier rather than adding spins themselves.
What does Triple Reaction mean in Opal Fruits?
It is Big Time Gaming’s name for the way winning symbols are replaced. New symbols arrive from above on the six main reels and from the side on the two horizontal reels, so a single spin can produce a run of reactions, each checked for fresh wins before the next one starts.
