Rainbow Riches Free Spins Slot Sites: Top Picks to Play Online in UK
Written by Jamie Smith
Rainbow Riches is a casino classic, so it is no surprise Light and Wonder sought to make the most of the slot’s popularity with a supercharged sequel.
Rainbow Riches Free Spins bumps up the fun factor with up to 999 free spins able to be earned in the bonus round, though the base game is quite limited and the maximum win of 500x the stake size is on the low side compared to most new slots at UK online casinos.
The best Rainbow Riches Free Spins casinos in the UK for real money play are safe and secure, with the right licenses to make sure they can operate legally.

Our full review of Light and Wonder’s Rainbow Riches Free Spins takes a deep dive into the slot’s details, from the game grid, theme and RTP through to how the bonus round works.
Overview of the Rainbow Riches Free Spins Slot Game
Rainbow Riches Free Spins in Brief:
- Release Date: March 2022
- Type: Video Slot
- Theme: Irish, Magic

- RTP: 95.17%
- Volatility: Medium-High
- Special Features: Wilds, Scatters, Free Spins

There is no doubt Rainbow Riches Free Spins is a simple-looking slot, but that is not a bad thing with not many features for players to understand when they fire it up.
The game grid is uncomplicated and the bonus round provides a lot of fun, though the graphics look quite dated when set side-by-side against a lot of the new slots launching at UK online casinos these days.

Rainbow Riches Free Spins Bonuses & Features
Special slot features on Rainbow Riches Free Spins are dominated by the excellent bonus round, with as many as 999 free spins able to be earned here. Three scatter symbols unlock the Rainbow Riches Free Spins bonus round, with these only able to appear on the first, third and fifth reels of the slot.
Three scatters pays 10 free spins, which bumps up to 15 free spins for four scatters and 20 free spins when five scatter symbols pop up from the same spin. Bonus icons can stack on the first reel only.
In the Rainbow Riches Free Spins game, the scatter symbol acts as a second wild symbol, which can help to increase the rewards on offer during the bonus round.
Similar Games & Best Alternatives
Rainbow Riches Free Spins is not the most imaginative slot, but it does at least offer something extra from the original Rainbow Riches game, which remains a popular pick at a lot of UK online casinos.
Fans of the series can also try out games like Rainbow Riches Power Mix – where players can land a maximum win of 12,500x the stake size – and Rainbow Riches Power Pitch, which has 96% RTP and medium volatility.
Other recommended Light and Wonder slot games at UK online casinos include Medusa Megaways and Wizard of Oz Ruby Slippers.
Free Spins Add to Rainbow Riches Legacy
The bonus round on Rainbow Riches Free Spins is what really makes the game sing, with players able to land as many as 999 free spins due to them being retriggered on a regular basis.
But the Rainbow Riches Free Spins base game lacks excitement and a lot of UK online casino players could be put off by the low maximum win of 500x the stake size, though the low minimum bet is a plus point.
