Rainbow Riches Megaways Slot by Light & Wonder

The reason to chase the bonus here is a single rule: the win multiplier during free spins never resets and has no ceiling. It opens at x1 and climbs by one after every winning cascade, so a long string of tumbling wins can leave you spinning at x12 or x20 with plenty of round left to run. Four Pot symbols anywhere on the main reels start it at 12 spins, and each extra Pot adds five more. Inside the round, +1, +2 and +3 symbols on the top reel top the counter back up, and clearing them off triggers fresh cascades of their own.

That top reel is where most of the unusual stuff lives. It sits horizontally above the four central reels and drops one extra symbol onto each, which is what pushes the count up to the full Megaways spread of 117,649 ways to win. The wild lives only up there too, never on the six main reels, and stands in for everything but the Pots. The same top reel hosts the Super Gem: land it and every gem on screen turns into one randomly chosen gem before paying, which on a busy board can blanket the grid in a single colour.

Visually it is the bright Irish-luck postcard the series has always run with. A gold-edged grid over a green meadow, a rainbow bending across the hills into a pot of gold by a wooden fence, a thatched cottage off to the left under a clear blue sky. The reels mix playful coloured card royals with chunky faceted gems in purple, blue, orange and green, and wins keep cascading as long as fresh combinations land.

If you would rather not wait for four Pots, the Buy Pass hands you the bonus for 100x the bet, or Take a Chance lets you gamble a smaller amount on a wheel: land the green and you get at least 12 spins, miss and the stake is gone. There is also a Bonus Bank that quietly siphons base-game wins into a pot that knocks down the Buy Pass price, all part of how Light & Wonder dresses the old Barcrest brand for the Megaways era.
