Blazing Rainbows

Blazing Rainbows: Familiar Territory

Blazing Rainbows sees Playtech step into one of the most crowded corners of the slots market — pots of gold, rainbow trails and lucky Irish charm, complete with the green colour schemes and folklore imagery that have become genre shorthand. Standing out in this space is genuinely difficult, and Blazing Rainbows leans on a specific collection mechanic to try to carve out its own identity.

Core Mechanic

The game is built around overlay symbols that stay active for several spins after they land. Whenever prize symbols or pots land on those marked positions, a rainbow trail feature kicks in, collecting the prize and potentially pulling further prize symbols down from above the grid. When multiple prize symbols stack together, a single trigger can chain into a genuinely lengthy collection sequence. Some overlays also carry a x2 modifier, doubling everything gathered during that particular trail — easily the most engaging part of the game, turning an otherwise ordinary spin into something more valuable.

Prizes and Jackpots

Prize values are generally modest, ranging from small cash awards up to larger jackpot-style pots. Mini, Minor, Major and Mega rewards can all appear, with the top fixed jackpot prize reaching 500x the bet on its own.

Free Spins

Landing three or more scatters triggers six free spins, during which the overlay symbols become persistent — staying active for the whole bonus round instead of expiring after a few spins. That's designed to create more opportunities for rainbow trail collections and longer prize chains than the base game allows.

RTP, Volatility and Betting

Blazing Rainbows carries a 95.9% RTP alongside medium volatility, with stakes running from 10p up to a sizeable £500 per spin — giving high-rollers plenty of room to work with. The maximum win is set at 5,000x the stake, and a 40x bonus buy is available for players who want to jump straight into the persistent-overlay free spins.

Verdict

Blazing Rainbows offers a competent, well-produced spin on an extremely familiar theme, with the stacking rainbow trail collections providing the game's best moments. It won't reinvent the pot-of-gold slot format, but the persistent overlays in free spins add a reasonable amount of extra chain potential. Released in May 2026, it's worth checking out via the free demo at johnessyslots to see whether the rainbow trail mechanic clicks before playing for real money.
