What Spinomenal Is Known For
Spinomenal’s identity in the slot market comes down to two things: ancient-world themes executed with strong visual detail, and a reliable application of the Book mechanic β a free spins format popularized by Novomatic’s Book of Ra where one symbol expands to fill entire reels during the bonus round. Spinomenal has built numerous titles around this mechanic, each with its own theme and RTP, making them particularly popular with players who already know and enjoy the format from other studios.
Beyond the Book titles, Spinomenal has developed Hold & Win mechanics β where coins land on reels and a respins feature locks them in place while you collect more β and a growing range of high-volatility titles aimed at players chasing big single-session wins. Their release pace is fast: multiple new titles per month means the catalogue is always expanding.
The Book mechanic works like this: trigger the free spins (usually by landing 3 scatter symbols) and one symbol is randomly selected as the expanding symbol for the entire bonus round. When that symbol appears anywhere on the reels during free spins, it expands to fill the full reel β creating potential for 3, 4, or 5 full reels of the expanding symbol simultaneously. On a high-paying symbol with a multiplier, this mechanic delivers the highest single-round wins in the Spinomenal catalogue. Spinomenal applies this format to Egyptian, Norse, Celtic, and Arabian themes, each with distinct art and paytable values.
Spinomenal’s Hold & Win titles use a respin mechanic triggered when a set number of coin symbols land simultaneously. The reels lock, coins stay in place, and you receive 3 respins β each new coin landing resets the counter back to 3. The round ends when respins run out or all positions are filled. Coin values range from small fixed amounts to jackpot prizes (Mini, Minor, Major, Grand) displayed on the coins themselves. Full-board fills β every position covered in coins β deliver the Grand jackpot. This mechanic runs across multiple Spinomenal titles with different themes and jackpot values.
Spinomenal’s high-volatility catalogue targets players who accept extended dry spells in exchange for outsized bonus round potential. These titles typically offer max wins in the 5,000xβ10,000x bet range, with free spins features that can be retriggered and multipliers that stack across the round. The Ante Bet feature β paying an increased bet (usually 25% extra) to double the frequency of scatter landings β is available on select titles and is particularly useful for bonus-hunting sessions where triggering the free spins quickly is the goal.

Spinomenal’s Theme Strengths
Spinomenal has built more Egyptian-themed slots than almost any other category in their catalogue β pharaohs, gods, scarabs, books of spells. If you play Book of Dead (Play’n GO) or Book of Ra (Novomatic) regularly, Spinomenal’s Egyptian titles use the same mechanic in a different visual wrapper. Book of Cats, Book of Cleopatra, and Gods of Giza are the strongest performers in this vertical. Each has a distinct symbol set and RTP β check the paytable before choosing which one to run your bonus on.
Spinomenal’s mythology titles β Book of Poseidon, Legacy of Dead Gods, Thor’s Vengeance β apply the same Book mechanic to Nordic and Hellenic settings. These titles tend to run slightly higher RTPs than the Egyptian catalogue and carry strong visual production quality. The mythology theme allows for larger, more dramatically designed expanding symbols which adds to the visual impact of a full-reel hit during free spins.
Not every Spinomenal title is a high-volatility bonus hunt. Their classic fruit slot range β 20, 40, and 100 payline titles with BAR symbols, sevens, and bells β delivers low-to-medium volatility play with steady hit frequencies. These titles are useful for wagering bonus funds at lower variance. 40 Mega Clover is the most-played classic format in the Spinomenal catalogue and contributes 100% toward the casino bonus wagering requirement at BetWhale.

Frequently Asked Questions
What type of games does Spinomenal make?
Spinomenal focuses almost exclusively on video slots. Their catalogue of 300+ titles covers three main mechanics: the Book expanding-symbol free spins format (their signature), Hold & Win coin-collection respins with tiered jackpots, and classic multi-payline fruit slots. They also have Megaways-licensed titles that use the variable-reel engine for very high ways-to-win counts.
How does the Book mechanic work in Spinomenal slots?
In Spinomenal Book titles, the free spins round is triggered by landing 3 or more scatter (book) symbols anywhere on the reels. At the start of the free spins, one symbol is randomly selected as the expanding symbol. Whenever that symbol appears during free spins β in any position on any reel β it expands to cover the entire reel. If the expanding symbol lands on multiple reels simultaneously, the win can be very large. Free spins can typically be retriggered by landing additional scatters during the bonus round.
What is the Ante Bet feature in Spinomenal slots?
The Ante Bet feature is available on select Spinomenal titles and increases your total bet by a fixed amount (typically 25%) in exchange for a higher frequency of scatter landings β which means more frequent free spins triggers. It is useful if your priority is triggering the bonus round quickly rather than minimizing cost per spin. The feature can be toggled on or off before each spin on supported games.
