1. Día de los Muertos Respins
Who says the afterlife can't be a good time? Día de los Muertos has the highest RTP in the lineup at 96.21%, and it plays on 10 fixed paylines. The line bet is your total bet divided by 10.
The Wild turns up on reels 2, 3, and 4, and it can stand in for every symbol. Even better, it doubles your win when it helps form a winning combination.
The real party is the Respins feature, where the reels spin for free and every win is doubled. Here's the fun part: every winning combination earns you more respins.
- 5-of-a-kind: 5 respins
- 4-of-a-kind: 2 respins
- 3-of-a-kind: 1 respin
- 2-of-a-kind: 1 respin
Your bet is locked during Respins, and all your wins are paid as one sum when the feature wraps up.
2. Phantom's Plunder
Ahoy, ghosts! Phantom's Plunder sends you hunting for treasure with 4,096 ways to win and a theoretical RTP of 92.17%. Wins form when matching symbols land on adjacent reels from left to right, and the way bet is your total bet divided by 10.
The Wild is a treasure chest, and it fills in for everything except the Scatter. The Scatter is a Free Spins Crest, and it opens the door to Phantom Free Spins. Mystery Scatters can also pop up on any base game spin, adding 1 to 5 Mystery Scatters to the reels to boost your chances of triggering the feature.
Land 3 or more Scatters and you'll get free spins:
Scatters | Free Spins | Retrigger |
|---|---|---|
3 | 7 | 3 |
4 | 11 | 5 |
5 | 15 | 7 |
6 | 19 | 9 |
7 | n/a | 11 |
Now for the ghostly twist. During Free Spins, you collect Special Phantoms holding keys, and 10 of them completes a single symbol collection. Fill a counter and that symbol turns into the Phantom symbol for the rest of the free spins. You also get 1 extra free spin for each completed collection, and up to 4 symbols can become Phantoms.
Hunt Ghostly Pirate Treasures
Spin across 4,096 ways to win with phantom symbol collections.
3. Zombie Cat Apocalypse
The end is nigh, and it's got whiskers. This 3-reel slot keeps things simple with 5 paylines, a 94.50% RTP, and a max win of up to 700x the bet. The Power Bet RTP is 94.50% as well.
Wins pay left to right on adjacent reels, starting with the leftmost reel. Wilds substitute for all symbols, and they land with multipliers of 1x, 2x, 3x, 5x, or 10x. When multipliers meet in a winning combination, they multiply each other. The 10x only shows up during the Re-Spin.
That Re-Spin kicks in when a Wild lands on all 3 reels. The 3 Wilds stay held in place while the reels and Wild multipliers spin once for free, and more Wilds can land. It ends after the re-spin finishes or when the win cap is reached.
There's a Nudge feature in Zombie Cat too. Reels 2 and 3 can randomly nudge into a better position to create a win, and it has nothing to do with your bet.
4. Count Catula: Hold n' Win
Meet the cheekiest count in town. Count Catula: Hold n' Win has a 94.51% RTP and a max win of up to 20000X the bet.
Keep an eye out for Catula Unleashed, which may randomly drop a CATULA onto the reels on any regular spin. This sneaky fellow collects the values of every COIN MONEY and COFFIN symbol on screen. COIN MONEY values run from 1x to 500x, and COFFIN values run from 0.5x to 2000x.
Get 3 or more COFFIN symbols and Hold n' Win begins. Your coffins lock in, and you get 3 re-spins. Only COFFIN, COFFIN MULTIPLIER, BONUS, or CATULA symbols can land, and each one resets the re-spins back to 3. COFFIN MULTIPLIER symbols bring x2, x3, or x5, and BONUS symbols award one of 4 instant prizes.
3 or more SCATTER symbols bring 10 FREE SPINS, with another 10 if you retrigger.
5. Blood Bank Bonanza
Time for a heist with fangs. Blood Bank Bonanza has a 96.17% RTP, and it's all about the payways. Matching symbols need to land next to each other from left to right, and only the highest win per payway is paid.
The Wild is a red chalice with red gemstones, and it covers for every symbol except the Scatter. The Scatter is a red crystal pendant labeled FREE SPINS, and it kicks off Heist Free Spins. Your bet is locked once the heist begins, and your winnings are paid in one sum at the end.
The best loot is hidden inside the heist. The high-paying vampires only appear during Heist Free Spins. Both variants pay the same, and they can pay in a mix. Six of them pay $10.00. The Bat leads the medium-paying gang with $7.00 for 6x, followed by the Black Cat at $6.50, the Candlelit Skull at $5.50, and the Coffin at $5.00. Mystery Scatters are listed at the bottom of the paytable screen.
6. Hysteria
Things get loud in Hysteria. This 5-reel slot has 243 payways, a 94.50% base RTP, and a max win of up to 20,000x the bet. The Power Bet RTP is 94.51%, and the Buy Feature RTP is 94.54%.
Wilds appear on reels 2, 3, 4, and 5, and they can turn Scatters into Wild Scatters, which work as a Wild and a Scatter at once. Midnight Frenzy can randomly strike on any regular spin, and every Wild stretches to fill its entire reel.
In Free Spins, a Bonus Multiplier grows with every spin:
- 5 Scatters: starts at 1x, climbs 1x each spin, up to 50x.
- 6 Scatters: starts at 2x, climbs 2x each spin, up to 100x.
- 7 Scatters: starts at 3x, climbs 3x each spin, up to 150x.
Wilds can expand on any Free Spin, and Scatters on every reel retrigger the round. The climb rate stays the same, and you can retrigger up to 4 times, up to a maximum of 50 Free Spins.
How to Pick Your Monster
Love a respin party? Día de los Muertos Respins is your jam. Treasure hunters will want Phantom's Plunder, and fans of simple, speedy spins should meet the Zombie Cat.
