What Symbol Triggers Mystery at the Mansion Slot Bonus Free Spins?

Mansions are big enough to hold a million secrets. But they are also big enough to hold a million prizes and wins. So, by landing three or more of the mansion scatter symbol, players can trigger some free spin wins along with some multipliers.

  • Three mansion scatter symbols awards players with ten free spins and four coins.
  • Four mansion scatter symbols awards players with 20 free spins and 50 coins.
  • Five mansion scatter symbols awards players with 30 free spins and 400 coins.
  • Players can get a 3x multiplier with any of the free spins.

Paylines and Stakes

It may be next to impossible to solve a mystery in such a huge house, but it only takes 0.01 to 0.5 coins per spin to get a chance to win the 7,500 jackpot prize that the mansion hides.

Apart from this win, players can expect anything from 5 to 7,500 coins by landing 2 to 5 of the wild symbols on the reels. Although, if this proves to be difficult, there are still some low and high-paying symbols to help players gain more wins.


The high-value symbols consist of the bottle of poison, the note and dagger, the man with the gun, and the candlestick. By landing 3 to 5 of a kind on the reels, players can win anything from 10 to 500 coins.

On the other hand, the lower-value symbols (K, Q, J, and 10) can award players with two coins for landing 3 of a kind, and 100 coins for landing 5 of a kind.
