When Barcrest launched its classic fruit machine Rainbow Riches slot online in 2009 it became an instant hit, and remains so with slots fans of today. It has spawned many sequels and now. Thanks to SG Digital and BTG’s Megaways game engine and its resultant ways to win, this online slot classic has enjoyed the ultimate refresh.

Pros & Cons

  • Megaways game engine delivers up to 117,649 winning lines.
  • Base game bonus and dedicated Free Spins feature.
  • Classic game modernised with glitzy graphics.
  • Fewer bonus games than the original Rainbow Riches.
  • Requires multiple way wins to score big payouts.
  • Four Scatters required to trigger the Free Spins feature.

How to Play

Any slots fans familiar to  online and mobile games will recognise the layout, with the betting interface to the right of the reels with the bet toggle set to Total Bet rather than individual lines and coins.

This makes choosing bets easier so we can concentrate on the gameplay. As with all Megaways™ slots we have six reels to match symbols across, plus a top reel that straddles reels 2, 3, 4 and 5. Symbols from the top reel count towards winning combos across the other reels, allowing for more ways to win. The Cascading Reels feature pops all winning combos, allowing for more symbols to drop in their place to deliver further winning combos.


Fans of the original Rainbow Riches online slot will recognise the styling of the 10s through Aces that makeup the game’s lower paying symbols, while fans of various Megaways Slots like Who Wants To Be A Millionaire Megaways and Bonanza! will recognise the glittering gems that make up the higher paying symbols.

The Horseshoe Wild only appears on the top reel and substitutes for all symbols except Scatters. Look out for the shimmering rainbow Super Gem symbol, also on the top reel. The Megaways staple Gold Scatters return to trigger the Free Spins feature.


The bonus features in Rainbow Riches Megaways are the best shots to take big winnings from this game. Though there are only two, landing either can deliver the pots of gold at the end of the rainbow this slot’s leprechaun is guarding.

Bonus Name Bonus Explanation
SuperGem Bonus

The SuperGem symbol on the top reel transforms all gem symbols across the reels into the same matching gem symbol, which is selected at random.

Free Spins Bonus

We must land four or more Gold Scatters to launch the Free Spins Bonus. Four Scatters awards 12 free spins, with a further five free spins added for each additional Gold Scatter we land to trigger the bonus round.

We score extra free spins when we land the +1, +2 or +3 symbols on the top reel during the bonus game, which award the respective number of free spins.

Unlimited Win Multiplier

During the Free Spins, each win you get enjoys and increased Multiplier by one for each winning cascade, with no limit to how high it can go.
