Wolf Fang – Treasure Island

Wolf Fang – Treasure Island Overview

Wolf Fang – Treasure Island is a pirate-flavoured entry in Spinomenal’s Wolf Fang series, released on 22 June 2023. A wolf in a captain’s coat guards the reels, surrounded by jungle and tropical-island animals. The reels sit in a wooden frame, and a “30 lines” badge in the corner reminds you that the line count is fixed. The game runs on 5 reels with 30 paylines, and SlotCatalog lists an RTP of 90% (the game is offered with RTP ranges), a 1,000x maximum win and stakes from 0.30 to 300 per spin. SlotCatalog gives no volatility rating.

Symbols and Paytable

The wolf is the wild and can land stacked, covering a whole reel. Among the regular symbols, the in-game paytable lists these values for five, four and three of a kind:

• Parrot: 1000 / 200 / 40
• Monkey: 400 / 80 / 30
• Crab: 200 / 50 / 25
• Snake: 120 / 40 / 20
• A: 50 / 25 / 15
• K: 40 / 20 / 10

The paytable also explains the series’ key mechanic: a medium symbol may appear as a 1x2 or 1x3 stack, and it pays the same as a single 1x1 symbol. A tall symbol therefore does not pay more on its own, but it fills more positions and so helps complete lines across the grid.

Free Spins: Choose Your Mode

When the free spins trigger, the game lets you pick one of two modes:

• 20 free spins with 1x2 stacked medium symbols
• 10 free spins with 1x3 stacked medium symbols

The first option gives you twice as many spins with shorter stacks; the second concentrates the action into fewer spins with taller stacks that can cover a full reel. Players who want a steadier round will usually lean towards the 20 spins, while the 10-spin mode is the swingier choice. SlotCatalog also lists a Buy Feature for direct access to the bonus round.

The choice matters more than it looks. Because a stacked medium symbol pays the same as a single one, the gain from a taller stack comes from coverage: a 1x3 stack fills an entire reel and can connect to every line that passes through that reel. Twenty spins with 1x2 stacks give more chances, but each stack covers less of the grid.

What We Saw

We played at a line bet of 10, which is a total stake of 300 per spin across the 30 lines. The best spin we captured paid 1,400, or about 4.67x the stake. Another returned 1,250 (4.17x), and a smaller hit paid 300, exactly giving the stake back. The stacked wolf wild was involved in the bigger wins, where it linked several lines at once.

These numbers also put the paytable in context. A 1,400 win at a 300 stake is a solid base-game result, but it is still far below the 1,000x ceiling, which on this bet would be 300,000. Wins of that size need the free spins, the tall stacks and the wolf wilds to line up together, so most sessions are made up of smaller hits like the ones we recorded.

The Wolf Fang Series

Treasure Island shares its engine with Wolf Fang – Sakura Fortune, which offers the same free spins choice with a Japanese theme, and with Wolf Fang – Spear of Fire, a 5-line version with a 2,000x cap.

Who It Is For

This is a straightforward 30-line slot with a clear hook in the stacked medium symbols and the free spins choice. The listed 90% RTP is on the low side, so check which RTP version your casino runs, and try the free demo on the left first.
