3 Lucky Rainbows (SpinPlay Games) – Review & Demo Play

3 Lucky Rainbows Slot Overview

I step into an enchanted forest with a rainbow ending in three pots of gold above a 5x4 grid. The Irish Luck vibe is clear despite no Leprechaun on screen. The base game leans on stacked wilds, and the real action sits in the bonus rounds fed by coloured coin collects. Each coin feeds its matching pot, and any collect can randomly fire free spins with an upgrade. The game caps out at 5,000x stake, so the upgrades do the heavy lifting.

3 Lucky Rainbows Slot Information

3 Lucky Rainbows runs on 5 reels and 4 rows with 20 paylines active in the base game. Above the reels sit green, red, and purple pots that bank their matching coins. When Green Free Spins trigger, reels expand to six positions tall for up to 40 paylines. The layout looks neat on both desktop and mobile since the slot is built in HTML5. Wins form left to right on consecutive reels using the standard payline system.

Stake range goes from 0.20 to 50 per spin, which suits most budgets. The RTP sits at 96.47 percent and volatility is set to medium, a steady profile that fits the letter-collect jackpots and coin prizes. The top payout is 5,000x the bet, and that figure ties in with the MEGA jackpot in the red feature. You will see stacked wilds in the base game as well, giving it some lift between bonus rounds.

Symbols and Paytable in 3 Lucky Rainbows

Low-paying symbols are 9, 10, J, Q, K, and A, with five of a kind paying 1x the bet. High-paying symbols stay on theme, with a violin, harp, shoes, beer, and a four-leaf clover paying between 2x and 5x for five. The Wild is a pot of gold that substitutes for all pay symbols and pays 10x for a five-symbol line. Wilds land stacked on all reels, which can lead to tidy line-ups even before the upgrades kick in.

3 Lucky Rainbows Slot Features

Three pots of gold sit above the grid and coloured coins of the same hue are collected in each pot. Every time one or more coins are collected there is a chance the Bonus Round triggers, and the upgrade you get depends on which coins were present at the trigger. The base game is fairly barebones beyond the stacked wilds, and even a wild screen is capped by the 20 lines, so you really want the free spins features.

Green Pot of Gold Free Spins award 5 spins, and all reels grow to six symbol positions. That pushes the game to 40 paylines, and any stacked wild that appears will nudge until the entire reel is wild. The win tally happens after the nudge, so you often see full columns of wilds paying across many lines. This is the upgrade that makes the setup feel more alive, as the taller reels build out tidy line hits.

Red Pot of Gold Free Spins focus on jackpots over 10 spins. Coins can land with a cash prize equal to your current stake or a letter. The letters build MINI, MINOR, MAJOR, or MEGA. Fill a name and you hit 10x, 50x, 500x, or 5,000x your stake. Purple Pot of Gold Free Spins start with 5 spins and each coin can award a cash prize, plus one or two extra spins. A random 2x, 3x, or 5x multiplier applies on every spin.

Multiple Pot of Gold in 3 Lucky Rainbows

If multiple Lucky Coins land and the feature triggers, you get the extras from all relevant pots in one round. If the red pot is in play you receive 10 free spins, otherwise you start on 5. The purple upgrade's random multiplier applies to both line wins and coin prizes, while jackpots in the red feature sit outside that multiplier. This combo round is where the slot feels at its best, as the upgrades layer nicely.

3 Lucky Rainbows RTP, Volatility, and Max Win

The stated RTP is 96.47 percent with medium volatility. The ceiling is 5,000x the bet, which you can hit via the MEGA jackpot or an outlier streak in a souped-up free spins round. In the base game a line of five wilds pays 10x, so a full set of wild lines across 20 lines tops out at 200x. That underlines why the pot upgrades matter if you want a proper shot at the headline figures.

I have not seen a stated hit rate for the feature, and the trigger is random on coin collect, which can feel swingy. From my sessions the free spins arrive on a fairly regular basis, helped by how often coins show up. Be aware some releases use customisable RTP ranges, so check the info panel where you play. Players who enjoy balanced sessions and clear upgrade paths will find it a tidy fit.

3 Lucky Rainbows Review Summary

3 Lucky Rainbows feels tranquil yet lively. The setting is cosy, the stacked wilds keep the reels ticking, and the three free spins paths give you variety. I like how the upgrades can merge into a super bonus when several coins are involved, and the nudge on green spins can build chunky screens. The jackpots in the red mode are the straightest route to the 5,000x potential, and the letter collect keeps that chase engaging.

It is not a hyper modern presentation and some animations do feel a bit dated, yet the feature mix carries it. The base game is light, so I treat it as a feeder for the pots. With 96.47 percent RTP and medium volatility, it hits a sweet middle ground for longer sessions. As an Irish Luck slot with clear mechanics and a fair shot at upgrades, it earns a place in my rotation.
