Blazing Rainbows slot game brings a bright, feature-led slot experience to Slingo, with a 5x5 layout, 10 paylines, prize symbols, overlays and free games all part of the mix. It has a playful feel, but the gameplay is easy to follow once you know what each feature does.
On this page, you can get a clear look at what Blazing Rainbows is all about, how to play it at Slingo, and which features shape the game session.
Blazing Rainbows is an online slot game from Playtech with a colourful theme and a feature set built around prize symbols and overlay positions. The game is shown on a 5x5 reel layout with 10 paylines and a minimum bet of 10p.
A big part of the action comes from symbols landing beneath overlays. When that happens, the symbol can award its value straight away, then continue to cascade down into the overlay area and pay again until the rainbow runs dry.
There is also a free games feature, where overlays lock in place for six spins once triggered. That keeps the feature clear and easy to track from spin to spin.





Blazing Rainbows includes lower-value regular symbols as part of its main reel set. These help form the base of the game between feature moments.
For the current lower-value symbol list and any matching payout details, check the in-game paytable.




Premium symbols sit alongside the lower-value set and add more variety to the reel mix.
The exact premium symbols and their values can be viewed in the game information panel inside Blazing Rainbows at Slingo.

A wild symbol is typically used in slot games to support winning combinations, but the exact wild behaviour for Blazing Rainbows should be checked in the in-game paytable before play.
That gives you the clearest view of how the symbol works in the current version of the game.

Blazing Rainbows includes a feature trigger connected to free games. For the exact scatter symbol design, trigger condition and any placement rules, open the game paytable in Slingo Casino before you start spinning.
Prize symbols are one of the standout parts of Blazing Rainbows.
When a prize symbol lands beneath an overlay, it instantly awards its value. After that, the symbol keeps cascading down into the overlay and can pay out again along the way. This continues until there are no more prize steps left in that path.
It gives the feature a rolling feel and keeps the reels lively.
Overlay positions sit above the reels and play a central role in how prize symbols behave.
Instead of being a background extra, the overlays are part of the main feature flow. Prize symbols can move down through them, and during free games the overlays lock in place, which changes the feel of each spin and keeps the setup steady across the feature.
Free Games are triggered to unlock six spins.
During these spins, overlays lock in place, which boosts the chance of feature activity staying active across the round. That fixed setup gives the feature a different pace from the base game and makes it easier to follow how the symbols move through the overlays.
Blazing Rainbows also includes a Buy Feature.
This gives direct access to the free games part of the game instead of waiting to trigger it through regular spins. Before using it, check the stake and feature details shown in the game interface so you know exactly how it works in the live version.
