When I first booted up NetEnt’s Spice, I didn’t know what to make of it. A desert crime syndicate run entirely by turtles? It’s bizarre, but in a market flooded with generic Egyptian tombs and leprechauns, I’ll take it.
But once you get past the quirky mafia-reptile theme, you realize that Spice is a 96.09% RTP slot built around one very specific mathematical concept. If you are the kind of player who relies on landing big base-game symbol hits, you might want to look away now. But if you love cascading grids, building multipliers, and delayed gratification, stick around.
The Paytable is Terrible (And That’s the Point)
The paytable in Spice is completely flat, and every single combination pays less than your stake. Landing a six-of-a-kind line of the top Blue-Shirt Turtle or the Wild pays a measly 0.75x. A line of chilies pays 0.25x.
When I first saw this, I thought NetEnt had made a mistake. But after a few dozen spins, the engine clicked. You aren’t chasing symbols here because the symbols alone can’t pay for the spin. The actual value of this game lies entirely in the empty spaces they leave behind.
Building the Board: The Multiplier Squares
Every time you hit a winning combo, those symbols vanish in a cascade. The exact positions they vacated light up with a multiplier square starting at x2. If a new win lands on that exact same square during the cascade, the multiplier doubles. If a win crosses multiple lit squares, their values are added together before boosting your payout.
This is the beating heart of Spice. Your success comes down entirely to how these squares stack up. In my session, I had a pitiful three-of-a-kind brick win (worth 0.15x natively) land across squares summing up to 14. Suddenly, that junk win turned into an 8.40x payout, anchoring a cascade sequence that paid out nearly 18x my bet.

The downside is that you need wins to hit the exact same physical coordinates repeatedly. When that sequence misses, the board drops, clears nothing, and your spin is dead. It’s a mechanic that requires patience. If you’ve played YGR’s Gold Showdown x3072, you’ll be familiar with doubling multipliers, but while that game uses a global multiplier, Spice isolates the math to individual grid positions.
The Feature Lane: A Quirky Lifeline
Running above the main 6×5 grid is a sliding Feature Lane. It holds Wilds, Locked Wilds, and three specific modifier tools: a Dynamite Bomb, a Row Converter, and a 9-Square Converter.
Here is what makes this lane interesting: these modifiers act as dead-board rescues. They only drop into play when the reels cascade and form absolutely no win.
- The Bomb: Clears a 3×3 area and doubles any multipliers sitting under it.
- The Converters: Turn a whole row, or a 3×3 block, into one symbol to give the board another shot at a win.
It reads like a brilliant backup plan, but I have to be fair here, it doesn’t always work. Across my session, the lane stepped in to save a dead cascade a handful of times, but a couple of those “rescues” still ended up paying nothing. Watching a rescue mechanic trigger only to fail is a mildly frustrating experience.

Free Spins: Where the 15,000x Potential Hides
The base game resets your hard-earned multiplier squares back to zero after every spin. But trigger the Free Spins (3 to 6 scatters gets you 5 to 12 spins), and the training wheels come off.
During the bonus, multiplier squares do not reset.
Because the squares carry over, your early spins are all about building the board for later spins. If you manage to drop a Bomb modifier in the bonus, it doubles the persistent multipliers under its 3×3 blast zone, which can get out of hand quickly.
Hitting the game’s massive 15,000x win cap requires a very specific perfect storm. You need early bonus spins to hammer the same grid positions until those squares double past x32 and x64. Then, on your final spins, you need a premium Turtle or Wild to slash across those stacked multipliers. There is also a Super Free Spins tier, which starts when a Super Scatter is among three or more scatters, or from a golden +3 during Free Spins.
