Features:Megaways, Super Gem, Free Spins, Unlimited Multiplier
Rainbow Riches Megaways Review: Our Verdict
UnionSlots rating: 7.5/10. Rainbow Riches Megaways suits players who know the original but want much more movement and a higher ceiling. Everything builds towards the free spins, where each cascade adds 1x to a multiplier that does not reset until the round ends, so a long chain of wins can grow quickly. The catch is high volatility: the bonus needs four scatters, and the base game can stay quiet for a long time between features.
Pros
The free spins multiplier rises with every cascade and has no upper limit
Super Gem turns every gem on screen into the same symbol for bigger matches
12,500x max win from a familiar British brand
Cons
High volatility, with long dry spells between bonuses
Free spins need four Pot of Gold scatters
The free spins round is the only bonus, so sessions depend on triggering it
On every spin the six main reels show between two and seven symbols, and a horizontal rainbow reel above reels 2 to 5 adds more, so the number of ways changes from 324 up to 117,649. Wins pay from the leftmost reel across adjacent reels. Winning symbols are removed in a cascade and new ones drop into the gaps; on the top reel, new symbols slide in from the right. The Lucky Horseshoe wild appears only on the top reel and substitutes for the regular symbols.
Super Gem
When the multicoloured Super Gem lands on the top reel, every gem symbol on screen turns into the same randomly chosen gem. That can create several matching combinations at once, and any win then starts a run of cascades.
Pot of Gold Free Spins
Four or more Pot of Gold scatters in one base game spin trigger 12 free spins, plus five more for each extra scatter, so six scatters give 22. During the round, +1, +2 and +3 symbols on the top reel add extra spins. The main draw is the Unlimited Win Multiplier: it starts at 1x, goes up by 1 with every cascade and stays in place until the free spins end, so later spins in a good round pay much more than the first ones.

RTP, Volatility and What to Expect
96% is the RTP most databases list for this game, but check the information screen at your casino, as some sources show a lower setting. High volatility means the return is concentrated in the free spins: expect plenty of small or empty spins in the base game and occasional large wins once the multiplier has climbed. The 12,500x max win is the cap on a single game round.
Playing Rainbow Riches Megaways in the UK and on Mobile
Rainbow Riches Megaways runs in the browser on iOS and Android. At UKGC-licensed casinos the stake is capped at £5 per spin (£2 if you are 18–24), and autoplay and turbo are switched off. The bonus buy offered in some other markets is not available to UK players, so the free spins can only be triggered in play. Demo mode is available at most UKGC casinos after registration and age verification.
