The 10 best Halloween slots
1. Big Bass Halloween 3 (Pragmatic Play, 2025)
| RTP | 96.5% |
|---|---|
| Volatility | High to very high |
| Max win | 5,000x |
| Layout | 5 reels, 10 paylines |
Big Bass Halloween 3 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. Newer still is Big Bass Halloween Splash 1000, released on 12 October 2026: a medium-volatility 5×3 slot with a 96.50% top RTP (95.50% and 94.50% versions exist), a pumpkin pick that can add up to five modifiers before the bonus, and a 20,000x max win. We haven’t reviewed it yet.
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 your line bet |
| 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. Read our full Halloween Fortune review.
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.
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 |

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.
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.
Prefer skeletons to pumpkins? Thunderkick’s Esqueleto Explosivo (low volatility, 700x max win) and Esqueleto Explosivo 2 (96.13% RTP, 5,000x max win) have exploding skulls and a Mucho Multiplier that grows with each drop. For zombies, Hacksaw Gaming’s Rotten (96.27% RTP, 10,000x max win) turns symbols into wilds with its SwitchSpins feature. For a Day of the Dead theme, Pragmatic Play’s Day of Dead (96.49% RTP, 4,500x max win) has walking wilds that step one reel left on each respin, and for werewolves there is Curse of the Werewolf Megaways (96.50% RTP, 40,976x max win). For something more comic than scary, Pragmatic Play’s Zombie Carnival (96.50% RTP, 5,000x max win) has zombie bear wilds that eat brain scatters to grow their multipliers in free spins.
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.

Halloween casino promotions: what to check
Many casinos run Halloween free spins, tournaments or reload bonuses in late October. 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.
