The highest in-game jackpot is 600x and is triggered by the symbol representing the Lord of the Manor. However, the fact that there is a 2x multiplier attached to all spins in the feature means this payout increases to 1,200x, and that’s just one payline!

If you bet just $1 on this slot, it is possible to win as much as $300,000 once the Free Spins are triggered and the Wilds, Multipliers, and extra spins are all taken into account.

The main symbol is represented by the Lord of the Manor. He is the star of the show and triggers the biggest payouts. There is also a Wild that can appear stacked and a Scatter symbol that triggers the Free Spin feature.

The Scatter can appear on the three middle reels and when it does the door to Wraith Manor will swing open and you’ll be ushered inside. You will receive 12 Free Spins, as well as 1 additional spin every time the Scatter makes an appearance. There are no limits to how many extra spins you can get, which means the Free Spins can continue until the payout cap has been reached.

Wilds become Super-Stacked during the Free Spins feature and all wins are multiplied by 2. There is also a feature known as invading Wilds, whereby a Stacked Wild reel can turn an adjacent reel Wild.
