The Turbo Storm Typhoon Demo from Koala Games
Turbo Storm Typhoon pays on 5 fixed lines across its 3×3 reels, where the triple-7 WILD returns 50x the total bet for 3 and gold cherries 30x. Alongside the lines, a PRIZE COLLECTOR confined to reel 2 picks up PRIZE values worth 1x to 15x or one of four jackpots topped by the 1,000x Grand, and the same two symbols lead into Hold and Win.
Line pays, PRIZE values, and rules match Voltage Blitz Egypt, which uses an ORB for the collector and lists a 94.26% RTP.
How to Play
Five Lines Beside the Collector
Three of a kind across one of the 5 fixed lines pays, read from the leftmost reel, with only a line’s best combination paid and separate lines totalled. The triple-7 WILD fills in for every line symbol but PRIZE and the collector. Turbo Storm is the other way to win: a collector on reel 2 landing with any PRIZE from reels 1 and 3 gathers every PRIZE value showing.
The Hold and Win Round
At least one collector on reel 2 and PRIZE symbols on reels 1 and 3 start the round with 3 respins. Collectors hold their place to the finish. PRIZE values are taken the instant they land, each new symbol sets the respins back to 3, and the game pays out the collector total once the feature closes.
Shortcuts Into the Feature
Turbo Surge may fire at random when a collector or PRIZE appears in regular spins, dropping in a random batch of both, always enough for Hold and Win.
The RTP Figure
Typhoon’s theoretical RTP is 90.31%, and a feature bought for 75x the total bet in the base game returns 90.29%.
