A dark underworld on 24 lines

The look is horror and underworld, with a dark tone throughout. Five reels carry 24 paylines, and a win needs a matching run of symbols on one of them.

Alongside the bonus buy sit the wild and the free spins. What a purchase actually triggers is explained inside the game, so read that screen first.

The 96.36% RTP and its high volatility

With 96.36% RTP, the house edge is 3.64% over a very large number of spins, which cannot say how any one evening will go. Casinos may configure the game differently, so the help screen shows the figure that applies to you.

High volatility spreads the payouts unevenly: fewer winning spins, some of them large, and a lot of empty ones between. That is a trait of the design, not a sign a payout is near. Our pages on volatility and RTP go deeper.

Buying the bonus

A buy option charges a fixed multiple of your bet to jump into a feature round. In a high-volatility slot, a few purchases that return little can drain a modest budget fast. Name a spending ceiling before you begin, and never lift it to win back a loss.

Hacksaw's range also includes Le Bandit, Klowns and Beast Below, all under Hacksaw Gaming slots. Adults only.
