Rainbow River Description
UK game studio S Gaming is the team behind this Irish-themed, Patrick’s Day title, which appeared in casino lobbies in March 2026, is another in a massive pool of reel spinners boasting rainbows and pots of gold motifs, along with a leprechaun as a title character.
Visually, this reel-spinning product feels very basic, as it has flat, colourful graphics that are a bit dated and lack a sense of artistic expression. They are rather generic, and the 5x3 gameplay here gets accompanied by a similarly generic Irish-style instrumental folk tune.
The gaming fun in the Rainbow River online slot is entirely beholden to a Pots o’Gold system that delivers three extra rounds, all of which are nothing unique but will probably be enough to keep sessions engaging for most casuals.

Rainbow River Bonus Features
There is really not that much to go into regarding the Rainbow River slot machine’s bonus features, as this spinner has one mechanic that can launch two variations of the same bonus, plus a wheel mode. We explain how you can start these and how they play out below.
Pots o’Gold Feature
This is this game’s core system, revolving around three coins – Yellow, Red, and Blue. On every spin, these can hit and activate a corresponding bonus. This does not happen automatically; the coins just give you a shot at activating their feature, which occurs at random.
The Blue and Yellow coins trigger two different variants of this slot’s Free Spins round, with the Yellow coins awarding up to seven spins in the Rainbow Wins, and the Blue ones up to nine in the Rainbow Spins.
The difference between the Blue-activated bonus – Rainbow Spins and the Yellow-triggered one – Rainbow Wins, aside from the number of awarded complimentary gaming rounds, is that in the Spins one, rounds play out sequentially, and in the Wins mode, they go on until the exactly designated winning spin count is achieved.
The Red coins award the Luck O’ The Wheel round, which is a wheel one, where you spin a twenty-segment wheel once for an opportunity to win a reward up to 100x your stake.
