Rainbow Riches Free Spins slot review
Rainbow Riches Free Spins answers the one complaint about the 2006 original — no free spins — by building an entire game around them. This Barcrest spin-off keeps five reels, three rows and ten lines, strips out the famous trail bonuses, and instead lets free-spins retriggers stack towards an extraordinary cap of 999 spins. It became a particular favourite in bingo-side lobbies and casual rooms, where its machine-cabinet looks and single-minded premise translate perfectly, and the 999 number itself has passed into slot folklore.
How Rainbow Riches Free Spins plays
The presentation deliberately mimics a physical machine, with the leprechaun and Irish iconography of the series across a simple ten-line layout. Base play is straightforward line-matching with a wild in support; the bonus symbols are the entire point, and sessions are paced around how often they arrive.
The free-spins engine
Land the trigger symbols and the round begins — and then, crucially, keeps feeding itself. Retriggers during the feature add further spins again and again, with the running total allowed to climb to a 999-spin ceiling that almost no other mainstream slot matches. Most rounds are modest, but the design openly dangles the possibility of a marathon, and long retrigger runs are exactly why the game built its following.
RTP, volatility and top wins
The published RTP is around 95.17%, marginally above the original Rainbow Riches, with operator versions varying — the in-game information panel shows yours. Volatility is medium: the spins themselves pay modestly, with the upside concentrated in how long a retrigger chain can run.
