Ribs Golden Crypt Slot Review
A skeleton king in gilded armour stands at a crypt door at dusk, one hand raised, autumn trees burning orange against a pink-purple sky. The paintwork is lovely, but the reason to walk through that door is simpler: Ribs Golden Crypt is one of those games where almost nothing pays properly until two multiplier systems collide in the same winning chain, and everything before that collision is loose change.
It’s a release from Slotmill running on a 6×6 grid with cluster pays, where wins need clusters of 5 or more identical symbols. The RTP is 96.01%, volatility is Very High, and the ceiling is 10,000x the bet. It joins the likes of Demon’s Gate, Dark Forge and Dead Man’s Crew in the studio’s darker corner of the catalogue.
Avalanche Cluster Pays and the Base Game
There are no paylines here. Every win starts with a cluster of five or more matching symbols touching on the 6×6 grid, and from there the Avalanche takes over: all winning symbols explode, new symbols drop into the gaps, and the chain continues for as long as new clusters form. Each avalanche win stacks onto the round’s total.
One extra detail makes the avalanches interesting. Any spin that produces a win cluster also creates a Wild on a random empty position, and the wild substitutes for everything except the Bonus symbol. Longer chains therefore feed themselves, with wilds appearing exactly where the space has just opened up.
All symbol pays are multiples of the total bet, and they step by cluster size rather than by position. The full ladder looks like this:
- W-plaque (Bonus column): 0.5x for 5 symbols, 0.75x for 6, 1x for 7, 1.5x for 8, 2x for 9, 3x for 10, 5x for 11, 7x for 12, 10x for 13, 15x for 14, 20x for 15 and 50x for a 20-symbol cluster
- Crown-skull (Multiplier column): 0.5x for 5, 1x for 6, 1.5x for 7, 2.5x for 8, 3.5x for 9, 4x for 10, 5x for 11, 10x for 12, 15x for 13, 20x for 14, 25x for 15, 30x for 16, 40x for 17 and 50x for 20
- Red imp: 0.4x for 6, 0.6x for 7, 1x for 8, 1.75x for 9, 2.25x for 10, 4x for 11, 5x for 12, 7.5x for 13, 11x for 14, 15x for 16, 20x for 17 and 30x for 20
- Pumpkin: 0.35x for 6, 0.5x for 7, 0.75x for 8, 1.5x for 9, 2x for 10, 3.5x for 11, 4x for 12, 6x for 13, 10x for 14, 12.5x for 16, 17.5x for 17 and 25x for 20
- Green ghost: 0.3x for 6, 0.4x for 7, 0.6x for 8, 1.25x for 9, 1.75x for 10, 3x for 11, 3.5x for 12, 5x for 13, 7.5x for 14, 10x for 16, 15x for 17 and 22.5x for 20
- Blue ghost: 0.25x for 6, 0.35x for 7, 0.5x for 8, 1x for 9, 1.5x for 10, 2.5x for 11, 3x for 12, 4x for 13, 5x for 14, 7.5x for 15, 10x for 16, 12.5x for 17 and 20x for 20
- Heart, Star and Moon: 0.1x for 5, 0.15x for 6, 0.2x for 7, 0.3x for 8, 0.4x for 9, 0.5x for 10, 1x for 11, 2x for 12, 2.5x for 13, 3.5x for 14, 5x for 15, 7.5x for 16, 10x for 17 and 12.5x for 20
The premium symbols only need five or six symbols to pay, while the four royals share identical values across the whole table. A 20-symbol royal cluster still pays 12.5x, which is what giant avalanches are for. Bets run across 22 levels in the casino’s currency, and the level can’t be changed mid-round.
Giant Symbols and Multiplier Meteors
Two grid features drive the multiplier, and they work together. Giant Symbols appear at random and always carry a multiplier between 2 and 10, which is added to the total win multiplier whenever the giant forms part of a winning combination.
Multiplier Meteor Symbols land with a random value of x2, x3, x5, x7, x10, x20 or x100. When there’s a round win, a meteor stays on the grid and only activates once the avalanches stop. At that point, all active meteor values are added together and the round’s total win is multiplied by the combined figure, on top of whatever the win multiplier has already built.
The win multiplier resets at the start of each new round, so a single big meteor is worth chasing only inside the round that’s already running. A x100 meteor sitting over a healthy avalanche chain is the route to the game’s biggest results.
Free Spins and Super Mode
Landing 3, 4 or 5 Bonus symbols awards 8, 10 or 12 Free Spins. The key change inside the round is that the multiplier doesn’t reset between spins, so Giant Symbol and meteor values accumulate across the whole bonus rather than evaporating each time.
There’s also Super Mode Free Spins, awarded randomly when the bonus triggers. In Super Mode, a Giant Symbol is guaranteed to drop at the start of every free spin, which means the multiplier gets fed on each spin without fail.
Fast Track, Xtra-Bet and Burst Mode
Fast Track is the game’s feature-buy panel, active in the base game only. Each option charges a fixed cost per spin based on your bet level, and it stays on until you switch it off by clicking the feature icon:
- Free Spins: 100x the bet, guaranteeing a triggering round, at 96.26% RTP
- Super Mode Free Spins: 500x the bet, at 96.46% RTP
- Giant Symbol: 30x the bet, at 96.10% RTP
- Gamble feature: 250x the bet, at 96.45% RTP
Xtra-Bet is the softer option, raising the base bet by 50% to improve the odds of triggering Free Spins by 2.1 times, with wins still evaluated on the base amount. It runs at 96.00% RTP, can only be toggled between rounds and can’t be combined with Fast Track. Autoplay has to be switched off before the toggle responds.
Burst Mode is a faster autoplay variant that keeps the same game logic but only displays the total win per round. It can be stopped at any point, with the session result shown once the last round finishes.
Our Honest Verdict
Overall Rating: 7.1/10
Playing this is a waiting game, and the king at the door knows it. Most rounds pop a small cluster, seed a wild or two, and die quietly; the appeal is the rare run where giants and meteors stack over a live chain and the total climbs somewhere interesting. That collision is the one reason to pick it.
The strength is the free spins round, because the multiplier finally stops resetting and twelve spins of accumulation, with Super Mode guaranteeing a giant every time, is the only place the ceiling feels reachable. The weakness is that the base game undoes that work every single round, and the royals pay so little that an average chain isn’t worth the wait.
It suits cluster-pay players who like a long build and a bonus worth building towards. Anyone after regular, meaningful base-game hits won’t find them here. The crypt is gorgeous at dusk, though, and the gold under the floor is real for those willing to dig.
