Infernal Trinity GO Guaranteed Slot by Play'n GO

Three phoenixes perch above the reels, and each one hands the Hold'n Spin a different upgrade depending on which coloured Tear Scatter you feed it. Collect the blue drops and the Blue Phoenix wakes up to expand the reels once you're in the bonus. Red feeds the Red Phoenix, which bumps up one Coin value. Purple feeds the Purple Phoenix, which forces one guaranteed Instant Win Coin onto the grid. You can trigger the Hold'n Spin with just one phoenix active, but the round only reaches its full shape when all three fire together.

The Hold'n Spin itself is standard sticky-coin territory. Coins lock in place, and every time at least one new Coin lands the counter resets back to three respins. Coins carry either cash values or one of the fixed Instant Win prizes: Mini at 10x, Minor at 25x, Major at 100x, and the Grand at 1000x. The bonus alone tops out at 2000x, so the four-figure ceiling on the paytable comes from stacking a strong Hold'n Spin against everything else the round can throw in.

What ties it to the rest of Play'n GO's GO Guaranteed titles is the ladder running down the left edge, labelled Top Multiplier. It climbs every spin where all three Tear Scatter colours land together. When a Hold'n Spin ends with all three phoenixes triggered, the game checks your collected Coins against that ladder value and pays the ladder instead if it's higher. It's a floor, not a bonus on top. The GO Ultra toggle raises that floor (the minimum shifts from 10x to 25x) and doubles every Instant Win, at the cost of a bigger bet.

Visually it leans hard into the underworld setting: a volcanic canyon of glowing orange lava, blackened rock, a castle silhouette burning in the sky, and the 5x4 grid set between two carved stone pillars. Card royals fill the low end while gold jewelled goblets and gem rings sit above them. If you want the mechanic without the fantasy dressing, the Instant Win coin ladder is the part doing the real lifting here.
