Secret Code is a gothic mystery-themed slot from NetEnt that plays out in dim, gaslit corridors filled with locked chests and hidden keys. Running on 5 reels, 3 rows, and 20 paylines, it stacks three separate bonus mechanics on top of a high-volatility base game, giving it more moving parts than most classic NetEnt titles.

An expanding wild can appear on the three middle reels and expands to cover the whole reel whenever it’s part of a winning combination. A standalone Bonus feature sends players into the game’s gothic corridors to match keys with chests for cash prizes, with an optional gamble round to risk half or all of that bonus win on another draw. Separately, landing scatters triggers a Free Spins feature where players choose a scatter symbol to reveal a starting multiplier, and every additional 2 or more scatters that land pushes that multiplier higher, up to a maximum of 20x.
Pros

- Free spins multiplier can climb as high as 20x on wins
- High volatility base game suits players chasing bigger swings
- Gothic mystery theme stands out from NetEnt’s more common fantasy titles
Cons
- Reported max win figures vary too widely across sources to state with confidence
- High volatility means longer dry spells between the bonus features
- Three separate bonus systems can feel busy compared to simpler NetEnt slots
