The 10 best Halloween slots
1. Big Bass Halloween 3 (Pragmatic Play, 2025)
| RTP | 96.5% |
| Volatility | High |
| Max win | 5,000x |
| Layout | 5 reels, 10 paylines |
The newest edition of Pragmatic’s Halloween fishing series arrived in October 2025. It keeps the fisherman-collects-fish free spins from the Big Bass games, with a bigger 5,000x max win than the first Halloween edition. Some casinos run lower RTP versions, so check the info screen.
2. Big Bass Halloween 2 (Pragmatic Play, 2024)
| RTP | 96.71% (lower versions exist) |
| Volatility | High to very high |
| Max win | 5,000x |
| Layout | 5 reels, 10 paylines |
The 2024 sequel has the highest top RTP of the three Halloween editions, and the max win rises to 5,000x. Like the others, nearly all of its value comes from the free spins, where the Fisherman collects fish values.
3. Big Bass Halloween (Pragmatic Play, 2023)
| RTP | 96.06% in most listings |
| Volatility | Medium-high |
| Max win | 2,100x |
| Layout | 5×3, 10 paylines |
The original Halloween edition is the gentlest of the three. 3 to 5 scatters give 10 to 20 free spins, and every 4th Fisherman collected adds 10 spins and raises the multiplier, up to 10x. Read our full Big Bass Halloween review.
4. Halloween Fortune (Playtech, 2012)
| RTP | 97.06% (a 92.96% version exists) |
| Volatility | Medium |
| Max win | 10,000x |
| Layout | 5×3, 20 paylines |
A classic with a high top RTP. Bonus symbols on reels 1 and 5 start the Witches’ Brew bonus: pick a witch to win 3 to 20 free spins, then a potion to set a 2x to 10x multiplier. Make sure your casino runs the 97.06% version, not the much lower one. Try the Halloween Fortune demo.
5. Blood Suckers (NetEnt, 2013)
| RTP | About 98% |
| Volatility | Low |
| Max win | About 1,014x |
| Layout | 5×3, 25 paylines |
One of the highest-RTP slots online. Free spins triple every win, and a coffin-picking bonus game pays cash prizes. The max win is small, but it is a good pick for long, steady sessions. Read our full Blood Suckers review.
6. Blood Suckers II (NetEnt, 2017)
| RTP | About 96.6% to 96.9% |
| Volatility | Low |
| Max win | About 1,298x |
| Layout | 5×3, 25 paylines |
The 2017 sequel keeps the vampire-hunting theme, the 25 paylines and the low volatility, with a slightly higher max win than the original. Sources list slightly different RTPs, so check the info screen. Try the Blood Suckers II demo.
7. Blood Suckers Megaways (Red Tiger, 2023)
| RTP | 97.66% (lower versions exist) |
| Volatility | High to very high |
| Max win | About 20,520x |
| Layout | 6 reels, up to 117,649 ways |
Red Tiger, NetEnt’s sister studio, turned the vampire classic into a high-volatility Megaways slot with cascading wins, random modifiers and a max win above 20,000x. A very different ride from the low-volatility original.
8. Immortal Romance (Microgaming, 2011)
| RTP | 96.86% |
| Volatility | High |
| Max win | 12,000x+ |
| Layout | 5×3, 243 ways |
A gothic vampire love story and a long-time favourite. The random Wild Desire feature can turn up to 5 reels wild, and the Chamber of Spins offers four free spins modes, from 10 spins at 5x up to 25 spins with Wild Vine. Read our full Immortal Romance review.
9. Halloween Jack (NetEnt, 2018)
| RTP | 96.28% |
| Volatility | High |
| Layout | 5×3, 20 paylines |
Walking wilds move one reel left on each respin, and wins with wilds are tripled. In free spins, collecting lanterns unlocks stronger wilds. Sources disagree on the max win, so check the info screen. Try the Halloween Jack demo.
10. Halloweenies (Microgaming)
| RTP | 95.52% |
| Volatility | Low to medium |
| Layout | 5 reels, 20 paylines |
A lighter, cartoon-style option. Bunny scatters give 13 free spins with a 3x multiplier, and pumpkin scatters start a pick-a-pumpkin prize bonus. Try the Halloweenies demo.
How to pick a Halloween slot
- For long sessions on a small budget: low-volatility, high-RTP games like Blood Suckers (about 98%) or Halloween Fortune (97.06%).
- For big-win potential: high-volatility games like Blood Suckers Megaways, Immortal Romance or Big Bass Halloween 2 and 3.
- For bonus-round fans: the Big Bass Halloween series, where free spins are where nearly all the value is.
- Always check the RTP version. The same game can run at very different RTPs depending on the casino.

Before you claim one, check the wagering requirement, the maximum bet while wagering, which games count, and the expiry date. Some high-RTP slots, such as Blood Suckers, are often excluded from bonus wagering. Read our welcome bonus guide for what to look for.
