The provider's signature mechanics and bonus features: what each one does and in which game to see it.
The bonus round is bought straight from the base game: for 50x the total bet in Volcano Rising SE, Mad Hit Marlin Bonanza, Go High Joker and Go High Panda, 60x in Mad Hit Full Steam and 100x in Gummy Giga Match, Sugar Rush Fever and Giga Match Egypt. In the Ten Ton Ways series players buy into the Hold & Win round for 75x their bet.
Example: Volcano Rising SE
The studio builds its free games differently: in Diamond Explosion a random reel is filled with Wilds and Diamonds on every free game, in Rush Fever only high symbols stay on the reels, and in Mad Hit Full Steam the Wild collects prizes worth x2 to x2000, with every four Wilds collected adding 10 more free games and raising the multiplier.
Example: Mad Hit Full Steam
In Mayan Cache and the J Mania series free games turn 30 lines into 243 ways to win, and Super Free Games add expanding Wilds on top. In J Mania Mayan Cache Dice, Super Free Games start when free games are triggered with a Super Scatter symbol.
Example: Mayan Cache
In the Stampede Rush series any Wild that lands may start a pick round with a guaranteed win: the Minor, Major or Grand jackpot or a large credit prize. The series' free games, with large stacks of Wilds, raise the chance of starting it.
Example: Elephant Stampede
In Diamond Explosion and Mad Hit it is a pick round for one of four jackpots (Mini, Minor, Major or Grand) with a possible multiplier of up to x10: a Wild starts it in the first series, a Mad Hit symbol landing with a Jackpot Diamond in the second. In Sugar Rush Fever the jackpot is picked by matching three levels and is doubled during free games.
Example: Diamond Explosion 7s
The Hold and Spin round of the Diamond Explosion series: six or more Diamonds trigger it, and adjacent prize symbols merge into bigger shapes for bigger prizes and jackpots. In the bespoke Diamond Explosion Candy and Pokerstars Mining Bonanza, six or more Prize symbols award 5 Explosion Free Games where neighbouring prizes combine as well.
Example: Diamond Explosion 7s
In the Giga Match series 8 or more identical symbols on the screen pay, with no lines: the winning symbols disappear, new ones fall from above and the cascade goes on while wins keep coming. In the Ten Ton Ways series symbols tumble from the main reels and the top reel, giving several wins from a single spin.
Example: Gummy Giga Match
Two or more consecutive cascades on one spin may start a pick round where three matching prizes are revealed: Mini, Minor, Major or Grand. Each further cascade raises the prizes, up to 10 times the starting ones; in the Giga Match series the Grand starts at 2000x and can grow to 20,000x.
Example: Gummy Giga Match
In Giga Match Egypt multipliers of up to x500 stay on the reels until the cascades end, then are summed and applied to the win, and in free games they accumulate for the whole round. Gummy Giga Match brings x2 to x100 multipliers in its free games, and in the Ten Ton Ways series Wilds on the top reel carry multipliers.
Example: Giga Match Egypt
Two or more Arrow symbols start a horizontal reel: each arrow collects prizes, including the Mini, Minor, Major and Grand jackpots, until it hits an empty position. In the Go High series the Hold and Win round starts with 4 rows and expands to 8 as more Prize symbols appear.
Example: Go High Joker
It may trigger on any base game spin: a symbol and a multiplier are chosen, and the reels hold only that symbol, Wilds with the multiplier and empty positions. New symbols and Wilds stay in place while spins keep adding them, and at the end line wins are multiplied by the sum of the Wild multipliers.
Example: Go High Joker
In the Immortal Ways series new Gold Coins hold their positions for 3 spins, and the Prize Wheel awards a jackpot, a credit prize, a multiplier or Collect. The whole array is won when coins fill every position or Collect lands on the wheel; in free games coins hold until the round ends and those left are paid at the end.
Example: Immortal Ways Diamonds
A grid of 10,000 ways to win, used by Immortal Ways, which the studio calls its most popular series, and by the Ten Ton Ways series. The studio says its Immortal Ways engine became an instant success.
Example: Immortal Ways Diamonds
The Hold and Win round of the J Mania series: six or more Prize symbols start respins, and filling the screen with 15 Prizes wins the Grand. When a Super Prize symbol starts it, Super J Mania upgrades every prize to a Super Prize for bigger wins.
Six or more Jackpot symbols start respins, and 15 of them on the screen win the Grand. When a Super Jackpot starts the round, every Jackpot is upgraded to a Super Jackpot (Super Jackpot Mania); the bespoke Yo Ho Ho has both rounds too.
Example: Mayan Cache
In Volcano Rising SE four or more Fireball symbols add 4 locked rows and award 3 respins; each new Fireball resets the respins, and collected Fireballs unlock rows with jackpots. The round can also start in free games, where every Fireball awards a prize.
Example: Volcano Rising SE
A Mad Hit symbol landing with Prize symbols pays their prizes at once, and in Mad Hit Marlin Bonanza a Mad Hit landing with a Wild expands the Wild to cover the whole reel. The series also has a sliding Mad Hit, and in free games Mad Hit symbols turn sticky for the rest of the round.
Example: Mad Hit Marlin Bonanza
Three or more Rush Fever symbols award instant credit prizes. In free games prizes for 5 or more of them are doubled, and every Rush Fever symbol pays 1x the total bet (Rush Fever Payment Feature).
Example: Sugar Rush Fever
The Hold and Win round of the Stampede Rush series: six or more Coins start respins, and one filled row wins the Minor jackpot, two rows the Major and all three the Grand.
Example: Elephant Stampede
Three or more Scatters let the player choose between the Stampede Rush round and free games with added Wilds. The series' free games bring large stacks of Wilds and another way into Stampede Rush.
Example: Elephant Stampede
In the Ten Ton Ways series the Hold & Win round starts with 6 or more Coin and Magnet symbols and gives 3 respins that reset with each new one. If at least one Magnet is present, Magnetic Wins follow: the top reel spins with credit prizes and jackpots collected above each Magnet.
In the free games of Mad Hit Full Steam the Wild collects Prize symbols; when a Wild lands with no prizes on the reels, the feature may add Prize symbols at random.
Example: Mad Hit Full Steam
The studio develops the game with the operator from concept and design to testing and launch, and it stays exclusive to the client: Immortal Ways Betano for Betano, Immortal Ways Mr. First for BetConstruct, Yo Ho Ho for Pokerstars, Stampede Rush Mighty Chang for Dafabet, Diamond Explosion Candy for Gaming1, Eredivisie Goal Collect with its Ball and Golden Ball features for Holland Casino.
