The Monster Power-Up Halloween Bonanza slot by 18 Peaches won our Game of the Month award for November, and before you ask, we promise it’s not just because of the spooky season. In fact, the smart mechanics found within had a strong say in it, along with the 10,000x max win. What Makes This Game Interesting With Every Spin Usually, new online slots don’t care that much about the base game, instead focusing on the bonus rounds. Well, in this one, each and every spin you make will land a power-up, which can totally change the outcome or the payout. Now, these power-ups kept me hooked because the free spins feature actually felt like a bonus, instead of a chase to actually get any payout. As shown above, each power-up sits at the top of the reels. You've got 2x, 3x and 5x multipliers, plus a W (meaning Wild), which will expand any wild landing on the reels. There are also the two arrows, handing out a free respin. The last two power-ups decide whether the slot pays right-to-left or vice versa. Another important feature This game has a customizable volatility, which, for me, keeps it interesting in the long run. I usually begin playing with the lower setting, switching it to high if I want something with a bit more spice. Where the Slot Gets To a Whole Different Level Yes, the base game is cool, but we still shouldn’t take the Halloween Bonus Game out of the discussion. That’s because 3 scatters give out 10 spins, 4 scatters open up 15 of them, and 5 scatters land no less than 20 spins. And let me tell you, everything changes within these rounds Enhanced symbols: Right away, the green blobby wilds turn into collectors (while still keeping their wild nature, of course). The spooky candies turn into value-carrying symbols, which can be collected by the blob I’ve just talked about. Progress bar: This bar fills as the collectors complete a stage, with 4 of them. The stages also apply multipliers to the collector: 2x, 3x, and 10x. You also get 10 free spins extra with each stage. Bonus game jackpots: There are 4 fixed jackpots, which can land during the free spins. Combining 3 or more coins of the same type can hand you 20x, 50x, 250x, or 1,000x of your stake. Peach skipTM: This button lets you skip the spinny part of free spins. It'll have the slot calculate the feature's total payout right away. You get a chance of doubling your win Although this feature isn’t tied to the free spins, it seems that this fresh title nods to the past with the gamble mechanic. After a win, you have the option of choosing between red and black. Choosing correctly will double your win, while choosing incorrectly will take the win away. How To Grab Free Spins Right Away The game allows you to buy the bonus round for 50x your stake, which is a pretty standard price for this feature. The Stats of Monster Power-Up Halloween Bonanza Sure, you can’t just pick up a game without first knowing how the payouts behave, regardless of how nice it is. Now, this Monster Power-up Halloween Bonanza slot is a touch below average in its stats, but not something to really worry about. Game Detail Value RTP 95.86% Volatility Customizable Max Win 10,000x Reels x Rows 5 x 3 Paylines 10 So, while the RTP and the grid layout are somewhat standard, the 10,000x max win is higher than that of some other slots, and the freedom of choosing your own volatility already tops my personal charts. Is It Really That Spooky? No, it doesn’t seem like 18 Peaches actually wanted to scare us. The symbols themselves are fairly cartoonish, yet detailed enough to tell without checking that the slot released in late 2026. The symbols are also expressive. The scatters feature a vampire (looking a lot like the one from Hotel Transylvania), and once you land 3 of these bloodsuckers (reminding me of other specific Halloween slots), the green blob will explode, announcing the bonus game that’s about to commence. Why This Game Got Our Award and Approval The Monster Power-Up Halloween Bonanza game won our Game of the Month award for November because it includes rare features that keep you involved with every spin. And, as a little secret, we love Halloween at SlotsMate, so we couldn’t resist falling for this eerie title. And while it might get you a bit involved, it's important to keep it fun. Spending too much money on slots isn’t really fun (or cool, to be fair), so keep an eye on your balance, gamble responsibly, and have a happy Halloween!
