Halloween season is when spooky slots usually run wild, but Games Global and INO Games clearly didn’t get the memo. Their monster-inspired game, Blooming Mystery, hit the online casino shelves in March, offering a fresh twist on the familiar Monsterville Secrets release.
Following up on its predecessor, the Blooming Mystery slot retains many key elements from the original. The 5x4 grid with 20 fixed paylines, creepy symbols, and Detective Friday all make a comeback. However, the setting, soundtrack, and special features get a spring makeover.
Is it enough for an entertaining gameplay? It's hard to say just yet—I like my sequels to push the envelope a bit more. But let’s not write it off too soon. Explore the theme, design, slot bonuses, and stats with me to see if this one’s got more than just a seasonal facelift.
INO Games might be fresh on the block, but it’s not afraid to shake things up. Blooming Mystery’s design is proof enough. The game combines eerie monster symbols and animations with a flowers-covered backdrop and a lively spring soundtrack.
I’m usually not big on these kinds of mashups, but somehow, this Halloween-meets-spring experiment works. It's too bad the same creative spark didn’t make it into the game’s setup.
Blooming Mystery sticks to a standard 5x4 grid with 20 fixed paylines and a left-to-right payout system. The symbols, payout potential, and $0.1–$20 betting range also stay true to the original.
Feel free to launch the Blooming Mystery demo at Casinos.com and compare it to the original to get a sense of similarities and differences firsthand.
Was it the right choice? I can’t say for sure. I enjoyed playing the game, even though the rewards weren’t great.
Whether you're new to online casino sites or a seasoned player, Blooming Mystery won’t give you a hard time. It’s easy to pick up and play, like all other slot games out there. Just be sure to glance at the paytable and betting toggles before spinning.
The game is packed with special features, so you’ll benefit from skimming through them first. I’d also recommend starting small with your bets until you get a handle on the action. After that, you can hit the Spin button and jump straight into action.
The game will serve a fresh symbol combination with every spin, offering a chance at different payouts. If three to five symbols match across an active payline, you’ll cash in anywhere from 0.1x to 10x your bet.
Like its prequel, the Blooming Mystery slot offers a rich selection of bonus features. Whether you’re a returning player or diving in fresh, this lineup is worth a closer look.
Wilds come in two forms—Spider Wilds and Golden Spider Wilds—both substitute base symbols to help you complete winning combinations. Yet, the former leaves sticky frames with multipliers worth up to 5x in their position, and the latter may add extra Wilds to the grid.
To further spice up the action, INO Games added a Bonus Buy and Gamble feature. The Bonus Buy lets you jump straight into Blooming Free Spins for 38.6x your bet, while the Gamble option doubles your chances of triggering this slot bonus for 19.2x your stake.
Given my recent Monsterville Secrets playthrough, I knew Blooming Mystery for real money would be fun.
I launched it at one of the top online casinos on our list, so the experience was smooth right from the start. I checked out the paytable and set my bet at the minimum level.
The first 10 spins were a bit dry, with just a couple of bucks here and there. But the eventful gameplay kept me hooked. I saw every bonus feature you could think of, from Spider Wilds to Nudging Scatters.
Once I raised my wager to $5, I unblocked the Blooming bonus round with 10 free spins. Detective Fridays appeared every other spin, so I reached the third Plant Monster on the Bonus Trail hassle-free. The round finished rewarding me $75, a good 15x my stake.
Betting between $7 and $20 didn’t lead to the same success, but the game remained entertaining. Wins were more spread out, but the payouts were bigger, and Wilds and Scatters showed up on every spin. My best payout was a $200 win with the max bet, with barely any effort.
If you plan to play it, you shouldn’t expect groundbreaking rewards but can count on having a good time.
The Blooming Mystery slot brings nothing new to the table stats-wise. The game features an RTP of 96.04%, a hit frequency of 35.27%, and medium volatility, just like Monsterville. It even replicates its prequel maximum winning potential—12,500x.
Was it the right choice? I can’t say for sure. I enjoyed playing the game, even though the rewards weren’t great. I guess it depends on what you’re after in a slot game. You can test it for free at Casinos.com and see what you think.
The Blooming Mystery slot is a fun revamp of the INO Games’ 2024 release, Monsterville Secrets. It offers little novelty in the structure department but gives the spooky original a lighter feel. The stunning visuals and upbeat soundtrack breathe new life into the gameplay, and the extensive bonus features keep it immersive.
Unfortunately, the winning potential remains as lackluster as in the prequel. If you’re chasing the big bucks, you may prefer the following titles:
