The provider's signature mechanics and bonus features: what each one does and in which game to see it.
BTG's patented mechanic that gives each spin up to 117,649 ways to win. The studio's catalogue files 48 games under Megaways, including Bonanza, Extra Chilli, Millionaire, Monopoly Megaways, Outlaw and Gold Megaways, and the Kingmaker bonus switches to Max Megaways. The studio licenses the mechanic to other developers.
Example: Bonanza
BTG's cascading reel system in which reactions run in both directions, including side-scrolling reactive symbols. The studio pairs it with Megaways in Bonanza, Extra Chilli and Millionaire.
Example: Bonanza
In BTG's reactions, winning symbols are removed from the reels. In Golden Catch reactions reveal Fish Bonus Prizes for every Boat above the reels, and Golden Boats in the base game multiply them by 10; in the Monopoly Megaways free spins reactions move MR MONOPOLY around the board and raise the multiplier. The catalogue also files a game under Triple Reaction.
Example: Golden Catch
Buys the feature at any time for a price that drops with every BTG coin the player lands: the player can wait for a lower price or go straight into the free spins. Featured in Extra Chilli and White Rabbit; the catalogue files 3 games under Feature Drop.
Example: White Rabbit
Direct purchase of the bonus round; the catalogue files 42 games under Bonus Buy. In Outlaw Free Spins cost 70 times stake and Enhanced Free Spins 300 times stake; in Burgers 12 Free Spins and in Golden Catch 10 Free Spins cost 100 times stake.
Example: Outlaw
Exchanges a big win for free spins; the catalogue files 23 games under Win Exchange. In Gold Megaways a win of 70 times stake or more can be traded at 70 times stake for 12 Free Spins, and a win between 20 and 70 times stake for a chance at them, shown in green on a wheel. It also appears in Burgers, Outlaw and Golden Catch.
Example: Gold Megaways
Reels grow during the free spins: in White Rabbit cake symbols add two extra symbols to the reels for up to 248,832 ways, and in Gold Megaways Expansion Symbols grow a reel to ten symbols for up to 1,000,000 ways, with 8 extra Free Spins and x3 Wilds on a full reel.
Example: White Rabbit
Gambles the free spins for more of them: in Extra Chilli the player can climb to 24 free spins, the first gamble a straight 50/50 and every later one tilted 60/40 in the player's favour; in Millionaire the Hot Seat gamble goes up to 50 free spins before the feature, with unlimited retriggers.
Example: Extra Chilli
Multipliers with no upper limit. Kingmaker builds its Anti Bonus mechanic on them: until the feature lands they grow on the four top-paying symbols, and in the Max Megaways bonus the four multipliers combine. In the Golden Catch free spins the Boat Multipliers are unlimited, and Extra Chilli and Millionaire also carry an unlimited multiplier.
Example: Kingmaker
BTG's series of 4,096-ways slots in which the player picks one of two completely different features: Danger High Voltage, The Final Countdown and Lil Devil. The catalogue files 7 games under 4096 Ways in all.
Example: Danger High Voltage
A Lil Devil feature the studio calls first to market: the player collects Heartstoppers that build towards an enhanced feature choice, the HEARTSTOPPER enhanced free spins. The catalogue files 2 games under Heartstopper.
Example: Lil Devil
Sticky wilds for the whole feature: in Danger High Voltage a random symbol becomes a sticky wild for the duration of the feature, and in the Outlaw Fallen Angel Free Spins an Ace, King, Queen, Jack, Ten or Nine becomes the Sticky Wild on reels 2 to 5, with a full reel of them awarding 3 extra Free Spins.
Example: Outlaw
A Gold Megascatter among the Scatters that trigger the Outlaw bonus turns the free spins into Enhanced Free Spins: Fallen Angel adds a second Sticky Wild, and in Dizzy In The Head the Ladder Wild multipliers, normally up to x77, climb up to x777. The catalogue files 3 games under Megascatter.
Example: Outlaw
BTG's own mechanic in Monopoly Megaways that brings the feel of the board game to a modern slot. Alongside it run the house collection and the free spins, where MR MONOPOLY moves around the board, raising the multiplier and adding spins, with unlimited retriggers.
Example: Monopoly Megaways
A secondary reel beneath the Burgers main reels that delivers up to 4 bonus outcomes per spin: Onion, Lettuce and Tomato multipliers boost the symbols above them, and Ice gives Wild Drink symbols a x2 multiplier; in the free spins the Ice Multiplier grows with every new Ice.
Example: Burgers
A BTG mechanic offered through the studio's license program alongside Megaways and Megapays: Megaways licensees can add Megaclusters to their portfolio. The catalogue files 6 games under MegaClusters.
A BTG mechanic that, the studio says, is available to all Relax partners; Megaways licensees can add it to their portfolio through the license program. The catalogue files 4 games under MegaPays.
