Rainbow Trinkets Slot Review
A rainbow arcs over a sunny meadow, a dark pot brims with gold at one edge, and a giant orange mushroom cottage fills the other. Rainbow Trinkets plays its Irish luck theme in full storybook handiwork: hand-drawn colour, drifting butterflies, a songbird perched above the reels, and a weathered wooden frame stitched with clover ornaments. It’s a lovely place to count symbols.
High 5 Games has given the familiar theme an unfamiliar shape: a 10×10 grid where wins are counted by symbol volume rather than lines, running at 96% RTP with high volatility. The studio’s appetite for oversized grids will be familiar from Da Vinci DeluxeWays, and the counting mechanic recalls Shadow of the Panther Infinity, but neither goes this wide. One bonus round carries the whole thing, and on a hundred positions it has to.
How the 10×10 Grid Pays
There are no paylines here. The grid holds a hundred positions, and wins are awarded purely by symbol count: land enough matching symbols anywhere on it and the pay tiers kick in. Each symbol type has its own entry threshold, scaled to its value, and the count has to reach that threshold before the symbol pays anything at all.
Position doesn’t matter, only volume. A spread of horseshoes scattered across all four corners pays exactly what a tight cluster in one corner pays, provided the count is the same. That single rule shapes everything else about the game, from the size of the grid to the height of the entry thresholds.
The premium icons, the Pot of Gold and the Horseshoe, start paying at just 24 matches. Mid-tier symbols need 34. The four cheapest icons, the gems and the heart, don’t pay a thing until 44 of them appear. All values are credit wins, shown without bet modifiers:
- Pot of Gold / Horseshoe
- 24 symbols – 800 credits
- 25 symbols – 1,000 credits
- 26 symbols – 1,200 credits
- 27 symbols – 1,400 credits
- 28 symbols – 1,600 credits
- 29 symbols – 1,800 credits
- 30 or more – 2,000 credits
- Green Hat / Red-Orange Boot
- 34 symbols – 900 credits
- 35 symbols – 1,000 credits
- 36 symbols – 1,200 credits
- 37 symbols – 1,400 credits
- 38 symbols – 1,600 credits
- 39 symbols – 1,800 credits
- 40 or more – 2,000 credits
- Orange Gem / Blue Gem / Heart / Purple Gem
- 44 symbols – 1,400 credits
- 45 symbols – 1,500 credits
- 46 symbols – 1,600 credits
- 47 symbols – 1,700 credits
- 48 symbols – 1,800 credits
- 49 symbols – 1,900 credits
- 50 or more – 2,000 credits
The shape of that ladder matters more than any single number. Every symbol group tops out at 2,000 credits, so a huge cluster of cheap gems pays exactly what a large pot-of-gold cluster pays. The premium symbols simply reach the ceiling sooner: a Pot of Gold group maxes out at 30 symbols while a gem group needs 50.
The steps between tiers are small and even. A Pot of Gold group gains 200 credits per extra symbol through the middle of its ladder, then the climb flattens at the 2,000-credit top. The same steady rhythm runs through all three tiers, which keeps the value of any additional symbol easy to read at a glance.
On a hundred-position grid, those thresholds aren’t abstract. Even the entry tier for the cheapest icons requires nearly half the grid to fill with one symbol type, which is why the counting format and the high volatility go hand in hand. Big counts are rare events, and the game is priced accordingly.
There’s no wild in this game. The one special symbol is the clover: clovers landing during the base game are collected, and three or more collected clovers trigger the Free Games Bonus. That collection meter is the base game’s entire structure, and it’s the only thing standing between a spin and the bonus round.
Free Games Bonus
The bonus is triggered by the clover collection, and the award scales with how many you’ve gathered:
- 3 clovers – 5 free games
- 4 clovers – 10 free games
- 5 or more clovers – 20 free games
Each free game opens with a twist. Before the rest of the grid fills, the game seeds it with a ready-made cluster: 5, 6 or 9 adjacent matching symbols of a randomly chosen type, dropped into a random position. Everything else lands around that seed.
Those seeded groups are the point of the round. A nine-symbol head start puts the pay tiers within reach in a way they rarely are in the base game, and a lucky seed of premium symbols goes further still. Every free game is a fresh draw on the same idea.
Be clear about what a seed can and can’t do. Even a nine-symbol Pot of Gold seed sits fifteen matches short of the lowest paying tier, so the seed alone never pays; it needs the surrounding fill to cooperate, and a cheap-symbol seed has further to travel still. The round rewards grids that pile on around the seed, not the seed itself.
The free games run on different reels to the base game, so the mix of symbols feeding those seeds isn’t necessarily the one the base game deals. They play automatically at the same bet multiplier as the spin that triggered the round, which keeps the stakes exactly where you left them.
Free games can’t be retriggered: the bonus runs to its final spin and ends when none remain. Twenty games is the ceiling, so there’s no snowballing once you’re in.
It’s a compact design. One trigger, one seeded-cluster mechanic, no retrigger, no second feature layered on top. The round either produces a big cluster early or it doesn’t, and the count thresholds do the rest.
Our Honest Verdict
Overall Rating: 7.1/10
Rainbow Trinkets is a counting game, and an honest one. Every spin tells you exactly where each symbol group stands, the clover meter gives the base game a clear destination, and the free games hand you a head start on every single spin of the round. That seeding is the best thing here: a nine-symbol head start turns counts the base game can only dream about into live possibilities, over and over.
The weakness is the ceiling. Every symbol caps at 2,000 credits, so a monster Pot of Gold group pays no more than a lucky gem flood, and with no retrigger and no second feature, one flat round is all you get. Set against the meadow’s charms, that’s a narrow machine.
This one’s for players who enjoy a single mechanic done cleanly and the patience high volatility demands, and it’s a poor fit for anyone who wants layered features or a round that builds on itself. The rainbow’s drawn beautifully enough that the waiting looks good.
