The provider's signature mechanics and bonus features: what each one does and in which game to see it.
A classic gamble after a win: the player picks one of four cards dealt on the table against the Dealer’s card; if it beats the Dealer’s card, the win is doubled and the player can try again, up to 10 times, while a lost round ends the Risk Game with no win.
Example: Hell Hot 100
The studio lists Bonus Pop among the core features of many of its slots alongside the Risk Game: Fortune Snake, Ninja, Football, Voodoo, Gladiators, Sushi, Geisha, Joker Stoker, Golden Ox, Minotaur ReBurn, Chance Machine 90s and Football 2026 offer it.
Example: Ninja
Free Games are triggered by Scatter or Bonus symbols, usually three or more: from 10 to 50 free spins depending on the slot and the number of symbols, and in many slots the round can be won again. Inside the round the studio adds multipliers, accumulated Wilds, Wilds that stay in place until the feature ends and guaranteed Wild symbols, as in Thunder Crown.
Example: Joker Stoker
Multipliers in the base game and bonus rounds: x2 in Green Slot when the same symbols fill the reels at once, x2 Wild multipliers in the Free Games of Ninja, x1–x3 multipliers on the Geisha symbols, x2 on every spin win in the Gladiators bonus and up to x100 in the Free Games of Fortune Snake; Monstroland adds a Progressive Multiplier and Minotaur ReBurn an unlimited re-spins multiplier.
Example: Fortune Snake
In the Free Games of Fortune Snake firecrackers explode after regular symbols pay, blast the symbols of their line and reel except multipliers and Bonus symbols, and produce further tumbling.
Example: Fortune Snake
Wild substitutes for other symbols in combinations, as a rule except Scatter and Bonus symbols, and in some slots it pays on its own: five Wilds in Geisha pay 40x the base bet and three Wilds in Green Slot pay 160x.
Example: Green Slot
Scatter pays in any position on the screen and usually triggers Free Games: five Scatters in Hell Hot 100 pay 500x the base bet, and in Voodoo one symbol acts as both Wild and Scatter.
Example: Football
Wilds land stacked: the fire Wilds of Hell Hot 100 may cover entire reels, the Free Games of Joker Stoker come with Stacked Wild symbols, and in Sushi the stacked Wasabi Shoga turns Wild during the Free Games.
Example: Joker Stoker
In Ninja two or more Wilds in the base game fill a meter: five Black Ninjas add 100 Wilds, four add 30, three add 5 and two add 2. The accumulated Wilds are spent in Free Games, where the Black Ninja replaces symbols on reels 2–4 with x2 Wild multipliers.
Example: Ninja
The Hold and Win bonus game is part of the bonus set of Fortune Chests, Fortune Chests Dice and Bazaar Monkey; Monstroland has Crimson Hold and Win, 3 Coin Towers Dice a Dice Hold Bonus Game and Thunder Crown a Thunder Hold Bonus Game, while Zalatar, Druid’s Fortune, Chance Machine 90s and Football 2026 offer Hold and Win too.
The Pick Me / Pick’Em bonus game: Pick Me is one of the three Bonus Games of Fortune Chests and Fortune Chests Dice, Bazaar Monkey offers Pick’Em, Monstroland Mummy Pick’Em and 3 Coin Towers Dice Moonlight Pick’Em.
A jackpot-collecting bonus: the Jackpot Collector Bonus Game of Fortune Chests, the Jackpot Collecting Bonus Game of Fortune Chests Dice and Jackpot collecting in Bazaar Monkey, Monstroland and Druid’s Fortune.
In Crown Coins three or more coins trigger the Royal Treasury Bonus Game: the reels turn into a 3x3 grid, coins carry prizes of up to 15x the total bet and four Jackpots, MIN, MID, MAX and ULTRA, of up to 1000x the total bet, while the Royal Coin stays in place and collects the prizes of gold coins.
Example: Crown Coins
In Crown Coins, when coins land on one or two reels only, the Lucky Time feature can still trigger the Bonus Game; Thunder Crown has Lucky Time too.
Example: Crown Coins
Bazaar Monkey and Minotaur ReBurn have an expanding Wild, and in the Free Games of Voodoo the symbols of a winning combination expand to cover the entire reel.
Example: Voodoo
The studio names cryptocurrency support for its Satoshi’s Secret slot, one of the games it lists when it describes its portfolio.
Pile Feature is a feature of Lucky Stamps, a retro emergency-service themed 3x3 slot with 5 paylines; the game also has a Wild and the Medic, Fire and Crime Bonus Games, with a Max Win of up to 3200x.
Clover Time is the bonus feature of Clover Flames Dice, a game on a 5x5 dice grid with golden clover symbols.
