Above the main machine you’ll see a set of rainbow reels. Silver and gold pots appear here - both are wild. The silver replaces everything apart from the scatter. The gold substitutes for all symbols including the scatter.
Hope to see a Drops of Gold symbol land on reel 5 on the Rainbow machine following a spin. This drops any wild silver or gold pots onto the equivalent position on the main reel set. A new payout calculation is then made. This is known as the Drops of Gold Bonus feature.
Land 3 bonus scatter symbols on the same spin and you’ll trigger the Free Spins Bonus feature and with it, 8 free spins. Any extra 4 free spins are awarded for each extra bonus symbol that hits on the triggering spin. Re-triggers are possible here too with 32 free spins available in total.
As usual for an Barcrest slot game, you’ll be given the option to play using the Big Bet feature. This is a series of 5 linked spins where wins are accumulated and paid following the final one. The more you pay the more extras are awarded.
They include a Super Rainbow feature which adds extra wild pots to the Rainbow Reels, reel spins with the lower value playing cards removed, expanded Drops of Gold symbols which improve your chances of a pot drop and a 100 payline game engine that expands to 200 paylines if you trigger the Free Spins Bonus feature. The RTP improves if you play in Big Bet Mode, rising to 97.75% from the standard 94%.
The Rainbow Riches series is an extremely popular one. The latest instalment offers something a little different thanks to the Rainbow Reels. The Big Bet feature offers the best winning opportunities but starting at £20 it’s not a cheap option. If you’ve enjoyed the other games in the Rainbow Riches franchise, then Rainbow Riches Drops of Gold should offer plenty of appeal - Rainbow Riches Reels of Gold is also a very good alternative with a popular WMS game engine.
