The Rainbow Riches name has carried more than twenty titles across nearly two decades of UK slot gaming. Rainbow Riches Free Spins slot from Barcrest, now part of the Light & Wonder group, sits near the early end of that catalogue, released in February 2017 with a proposition as direct as its title. One feature. Free spins. A retrigger system running on alternative reels that can theoretically extend to 999 rounds. No Pots of Gold, no Road to Riches, no Wishing Well. Just the bonus symbol stacked on reel one, appearing on reels three and five, and the question of whether a stripped-back entry in a franchise this well-known can hold attention on its own.
The bonus symbol appears stacked on reel 1 and individually on reels 3 and 5. All three reels must show at least one bonus symbol to trigger the feature. The number of symbols visible on reel 1 determines the award. One grants 10 free spins, two grant 15, and three grant 20. During the bonus, an alternative set of reels replaces the standard configuration, shifting the odds toward more frequent wins and bonus appearances. The same trigger conditions apply inside the round, making retriggers possible on every spin. Additional bonus symbols on reel 1 during free spins add 10, 15, or 20 spins following the same count. The round ends when either no free spins remain or the 999 spin hard cap is reached.
Two symbols carry Wild function. The Rainbow Riches logo serves as the primary Wild, substituting for all symbols except the bonus and leading the paytable at x500 for five on a line. The Free Spins bonus symbol doubles as a Wild on reels 1, 3, and 5, substituting for all other symbols in those positions. This dual-source arrangement means three of the five reels can produce Wilds from two different symbols during any spin.
Ten lines are permanently active across a five-reel, three-row grid. Wagers range from £0.10 to £500 per spin. Symbols match from the leftmost reel across consecutive positions, with each line paying the highest combination multiplied by the line stake.
Free play unlocks the full bonus features, including retrigger options, without limits. Rainbow Riches Free Spins offers a 95.17% RTP with medium volatility. The maximum possible win is 500x the total bet, up to £250,000.
The table below reflects a £1.00 total wager (£0.10 per line across 10 lines). Returns rise and fall with whatever stake you set.
| Symbol | 5 | 4 | 3 | 2 |
|---|---|---|---|---|
| Rainbow Riches (Wild) | 50.00 | 20.00 | 5.00 | 0.50 |
| A | 30.00 | 10.00 | 1.00 | – |
| K | 20.00 | 5.00 | 1.00 | – |
| J / 10 / Q | 10.00 | 2.00 | 0.50 | – |
Four paying symbol groups populate the reels. The Rainbow Riches logo leads at 50.00 for five on a line at this stake and doubles as the Wild. The A and K pay at intermediate rates, while J, 10, and Q share identical values at the bottom. With just four tiers and ten paylines, winning combinations land infrequently during regular play. The return structure relies on the free spins round and its retrigger potential to generate meaningful payouts over time.
Rainbow Riches Free Spins leans entirely on its franchise name and a single bonus feature. The retrigger system with alternative reels and a 999-spin ceiling gives the free spins round structural depth, but the surrounding game offers no secondary features, no ambient audio, and a four-symbol paytable that produces sparse returns between triggers. At 2.5 out of 5, the score reflects a title where the brand does more work than the product. The free spins concept has merit. The execution hasn't been revisited since 2017.
The age is visible from the first spin. Celtic knot borders frame a grey reel background. Letter symbols look carved from textured stone. A leprechaun watches from the left of the screen with a knowing expression that hasn’t changed since the asset was first drawn. There is no ambient soundtrack, no win celebration beyond a basic chime and a few coloured stars shooting in from either side of the reels, and no animated transition between spins. The visual template predates Barcrest’s more recent output by several years, and without any real audio layer to fill the gaps, longer sessions can start to feel hollow in a way busier games usually avoid.
Our review session reflected that simplicity. The four-symbol paytable and ten paylines produced scattered wins at low rates during regular play. We triggered the free spins after roughly 40 dry spins when the bonus symbol appeared stacked on reel one alongside singles on reels three and five. The alternative reels during the bonus delivered noticeably more frequent connections, and a retrigger added 10 spins to the initial 10. The total return from the round was modest, but it confirmed the design intention. Without the bonus, there is almost nothing to sustain a session between triggers.
The Rainbow Riches series now spans more than twenty titles, from the original’s trio of bonus games through Megaways conversions, cluster-pay variants, and the mechanical ambition of later entries like Power Mix and Locomotion. Free Spins sits near the simplest end of that catalogue. For players already invested in the franchise, it offers a familiar visual wrapper around a single retrigger-focused feature. For everyone else, newer entries in the same series deliver more for the same brand recognition.
About as exciting as it gets, a brief fanfare celebrating a £15.50 win from a £1 spin during regular play.
