Harpoon Heist

About Harpoon Heist

Harpoon Heist is a pirate-themed slot from Light & Wonder, set on the high seas in search of sunken treasure. It runs on a 5x3 grid with 10 fixed paylines. The draw is a harpoon mechanic that shoots onto the reels to gather instant cash prizes, paired with a walking-wild free spins round.

At Midnite the RTP is 94% and the maximum win is 2,425.5x your stake. Volatility is medium, with the bigger results in the free spins where walking wilds and multipliers combine. The max win figure differs across sources, which is covered in the flags.

How to Play Harpoon Heist

Set your stake across the 10 paylines and spin. Wins form from two to five matching symbols from the leftmost reel, and Treasure symbols carry instant cash prizes that harpoons gather. Stakes at Midnite start from £0.10 per spin.

The free spins are the main feature. Landing three, four or five Scatters awards 6, 8 or 10 free spins. During the round, Wild symbols become Walking Wilds that move across the reels each spin, and reel multipliers apply, so several Treasure symbols landing with active multipliers is the route to the bigger wins. There is no bonus buy, so the features trigger through standard play.
