- Stacked wilds land on all five reels
- Jackpot ladder reaches 5,000x your stake
- Coin collect trigger arrives fairly often
Cons
- Base game offers almost nothing beyond wilds
- A full wild screen pays only 200x
- Bonus trigger frequency is never disclosed
- Customisable RTP ranges reward the operator
First look at 3 Lucky Rainbows
3 Lucky Rainbows is an Irish Luck release from SpinPlay Games, played on a 5x3 grid with a rainbow ending in three pots of gold above the reels. The base game leans on high-value stacked wilds and little else. Everything of consequence sits inside the coin collect bonus rounds, which is where my scepticism begins.
The pitch sounds tidy: collect coloured coins, fill the matching pot, unlock an upgraded free spins round. On paper yes, in practice rather less so, because the trigger fires randomly and the base game gives you almost nothing to chew on while you wait. I remain cautious here until the numbers back up the theme.

RTP, volatility and win potential
The headline RTP is 96.47% on the standard build, and that figure alone deserves verification. This slot ships with customisable RTP ranges, which means the version you actually load can sit well below the flagship number. I would sooner measure than take it on faith, since the operator picks the setting, not you.
Volatility reads as medium, which fits a game where the bonus arrives fairly often but rarely pays big on its own. Max win is 5,000x your stake, driven almost entirely by the Mega jackpot in the Red upgrade. A full screen of wilds tops out at just 200x, so the base game will not carry a session. The claimed max win needs testing before I trust it as anything more than a rare ceiling.
Symbols and the coin collect system
Premium symbols pay between 2x and 5x your stake for five of a kind, which is modest by any measure. The Wild pays 10x for five, substitutes for pay symbols and lands stacked on every reel. Those stacks are the only real engine in the base game, and even a screen packed with them caps at 200x.
Above the reels sit three pots of gold in green, red and purple. Coins of each colour drop into the matching pot, and collecting one or more gives a chance to trigger the bonus. Which pot fills decides which upgrade you receive. It is a neat idea, but the coin symbols do nothing on their own; they are purely a route into the features.

How the three bonus upgrades work
Three separate upgrades hang off the pots. The Green Pot of Gold Upgrade gives 5 free spins and expands every reel to 6 positions, lifting the grid to 40 paylines while wild stacks nudge fully into place before wins are counted. The Red Pot of Gold Upgrade gives 10 free spins with gold lucky coins carrying cash prizes or letters spelling Mini, Minor, Major and Mega. Complete a set and you claim 10x, 50x, 500x or 5,000x respectively.
The Purple Pot of Gold Upgrade gives 5 free spins where gold coins pay a cash prize or grant +1 or +2 extra spins, with a random multiplier boosting line wins and cash prizes each spin. Trigger with more than one pot and the extras combine; if red is involved you get 10 spins, otherwise 5, and the multiplier does not apply to jackpots.
Here is where the marketing promise wears thin for me. The bonus fires randomly off the coin collect, yet nowhere is the trigger frequency stated. The mechanic they sell often hides the flip side: without a published hit rate, you are betting blind on how often these upgrades actually appear. I treat the advertised regularity as a claim, not a fact.
