Our methodology of assessing video slots
-
- 200-spin test: We conduct a minimum of 200 spins on each Spinomenal video slot to gather sufficient data on its performance. This sample size allows us to observe patterns in payouts, bonus triggers, and volatility without relying on short-term luck.
-
- Fixed bet size: To ensure consistency, we use a standardized bet size (normally, $0.01 per line or other minimum allowed amount) across all spins.
-
- Video recording: We record a video of the entire 200-spin session for each slot, allowing players to see the gameplay and outcomes firsthand.
Spinomenal slots RTP
This is the most controversial aspect of Spinomenal slots. The point is that the studio has programmed its games to have fluctuating RTPs. This means that one online casino will promote the slot with a 96% return, while another Spinomenal slot casino has a 90% version of this game. When you visit the latter, you will hardly expect it to have a slot with a lower RTP.
Most gambling sites tend to install the slots that are more beneficial for them, not for players. Below, you can take a look at the Spinomenal online slots that have a variable return-to-player value.
| Slot Name | Max Win | RTP Variations |
|---|---|---|
| Wolf Fang – Apocalypse | 1,000x | 88.36%, 91.48%, 93.32%, 95.81% |
| Kitsune Sakura Fortune | 3,000x | 88.94%, 92.06%, 93.51%, 96.04% |
| Book of Rebirth | 5,000x | 88.94%, 91.71%, 93.96%, 96.14% |
| Western Tales | 1,000x | 88.97%, 91.01%, 92.85%, 96.20% |
| Lucky Mr Patrick | 1,000x | 88.94%, 92.06%, 93.51%, 96.15% |
| Majestic King | 300x | 88.69%, 91.52%, 93.77%, 96.31% |
| Zeus Unchained – Hold & Hit | 5,000x | 89.49%, 92.33%, 94.17%, 96.85% |
| Demi Gods IV | 2,000x | 88.94%, 91.71%, 93.96%, 96.14% |
Spinomenal casino with the highest RTP
Best Spinomenal slots online
Certainly, the word ‘best’ is largely a subjective judgement. The bonus-packed Book of Demi Gods (any version) can be a superb game for some guys, but a complete rubbish for others.
So, we tried to make the ‘top’ list based on the following criteria: the number and scope of bonuses, bet sizes (the more flexible the range, the better), visual style and RTP (the higher, the better). Besides, these slots have good feedback from gamblers.
| Rank | Slot Name | RTP | Bonuses (Number & Scope) |
|---|---|---|---|
| 1 | Hunting Treasures Deluxe | 97.88% | High (4+): Pick Your Prize, Free Spins with Win Respins, Extra Wilds, Multipliers |
| 2 | 8 Lucky Charms | 97.40% | Medium (3): Free Spins (5-20), Expanding Symbols, Lucky Charms multipliers |
| 3 | Demi Gods | 97.40% | High (5+): Free Spins with modifiers, Sticky Wilds, Multipliers, Shifting Reels, Buy Bonus |
| 4 | Wacky Monsters | 97.30% | Medium (3): Wild substitutions, Free Spins, Monster-themed bonuses |
| 5 | Wild Santa 3 | 96.20% | High (4): Expanding Wilds, Multipliers, Mystery Free Spins, Holiday bonuses |
| 6 | Koschei The Deathless | 96.04% | Medium-High (3-4): Expanding Wilds, Free Spins, Folklore triggers |

Are Spinomenal games fair?
Speaking honestly, we do not know exactly whether Spinomenal slots are fair because the provider’s official page gives very little information about this. At the site’s footer, they show a few licensing and certification bodies such as Gambling Commission and HGC (Greece).
However, the only testing company is BMM Testlabs which is shown with an unclickable logo. Besides, we failed to find details about independent testing of Spinomenal slots online.
Many reputable companies give positive reviews of the Spinomenal slots developer in terms of game fairness. Take a look at the positive reviews here: SIGMA, Casinos.com, GammaStack. We have collected a bunch of both good and bad opinions about Spinomenal online slots from real players:

Collect & Win Spinomenal online slots
As you might know, almost every big provider has some unique bonus mechanics invented in-house. For example, BTG was the originator of the Megaways engine, which is now used by many studios under a license. Another example is Nolimit City, which comes up with xBomb, xNudge and other unique bonus boosters.
Spinomenal also has a few one-of-a-kind bonuses and approaches, e.g. Collect & Win. Games of this kind are unusual and differ from the rest.
To begin with, each game features only one reel and one payline. A player is awarded when a winning symbol lands at the centre of the screen. The money can be collected immediately or accumulated. The latter option is more beneficial because the awards on the ladder grow with each new win.
Collect & Win slot screenshots
Games of this category are fun and unusual. They are perfect for low rollers because a bet usually starts at 1 cent.
Retro Gaming slots in the Spinomenal collection
This is a special category of video slots featuring a Retro Bet add-on. We have not met online casinos where the slots of this group are displayed separately. Anyway, these are the Spinomenal slots with three or five reels. Some of them have a retro vibe (e.g. Chase the Fruits), while others look modern.
The key feature in every Spinomenal online slot of this series is a Retro Bet button that activates a boost costing the initial bet size. For example, wagering $0.2 and turning the Retro Bet on, you will have to pay $0.4 in each spin.
Let’s look at the 20-line Snatch the Gold 2. Once active, the feature will place a sticky wild at the center of reel 3. It will be here during every spin until you disable it ansd return to the normal mode.
What’s the downside? Any winning combination will be calculated according to the original bet, not the boosted bet. You activate the Retro Bet by tapping the switch button at the top left (see screenshot 1). However, the payout table (screenshot 2) will not change.
So, when you finally land five diamond sacks on a payline at a 40-cent bet with the feature ON, you will win $0.2 / 20 x 200 = $2, not $4.
Another good example is a 777 Thunder Hits slot from Spinomenal.
As you know, some classic 3-reel slots offer a bonus payout for landing the highest-paying combo. In 777 Thunder Hits, this approach is implemented via the Retro Bet feature (see the screenshots above to make it clearer).
Spinoleague Online Slots Tournament
In February 2025, the provider announced continuation of the Spinoleague tournament with an astounding prize pool of 12 million euros. The tourney will run till the 4th of March, 2026, but we believe they will prolong it because of its popularity.
The Spinoleague comprises 8 tournaments, each with a few separate rounds, culminating in the Super Round. The campaign involves all Spinomenal best slots except for the ‘1-Reel Slot’ category. Featured games rotate but include popular titles.
