King's Mask Slot Review

Pick your free spins

The studio describes three free-spins options: 15, 10 or 5 spins, each tied to a different multiplier. The page does not give the multiplier values or how the round is triggered, but the shape of the trade-off is clear. Fewer spins come with a higher multiplier, so the short option concentrates the outcome into fewer results.

In practical terms the 15-spin option spreads the bonus out and the 5-spin option makes it more of a gamble on a few strong spins. Neither choice changes the overall RTP figure we list; it changes how the result of a bonus is distributed.

Ceiling and volatility

Our catalogue does not list a max win for King's Mask, but Play'n GO states that up to 10,000x the total bet can be won, which is $10,000 on a $1 stake. Read that as the studio's figure. The volatility is rated High, consistent with a design that lets you choose an even spikier bonus.

Five settings, five costs

Five RTP versions exist: 96.28%, 94.29%, 91.29%, 87.29% and 84.28%. Their house edges are 3.72%, 5.71%, 8.71%, 12.71% and 15.72%. Per $1,000 staked, the expected loss over a very long run runs from $37.20 at the top to $157.20 at the bottom, passing $57.10, $87.10 and $127.10 in between.

A $1 player spinning 100 times can expect to spend $3.72 at the best setting or $15.72 at the worst. The equivalent figures are $0.74 and $3.14 at $0.20, and $18.60 and $78.60 at $5. The active setting is visible in the game's information pages.

Eclipse of Gods and neighbours

King's Mask Eclipse of Gods, from 2024, lists 96.29% and steps up to Very high volatility. Close 2022 matches with High ratings include Rocco Gallo at 96.29%, Naughty Nick's Book at 96.28% and Count Jokula at 96.25%.

Who it suits

The free-spins choice lets each player tune the bonus to taste: more spins for a smoother round, fewer for a sharper one. The base rating is already High, so budgets should allow for long gaps. The free official demo shows the choice screen and the multipliers the studio page leaves out.
