About the Koala Games Turbo Storm Tempest Demo
Koala Games built Turbo Storm Tempest on a 3×3 grid that pays through collection rather than lines. PRIZE symbols on the outer reels show Instant Win values or one of four jackpots, a Mini 25x, Minor 50x, Major 150x, or Grand 1,000x the total bet, and a PRIZE COLLECTOR on the middle reel gathers them.
The game adds Hold and Win respins and a random Turbo Surge. Voltage Blitz Heat Rush uses the same rules with an ORB in the collector’s place and a 94.32% RTP, and it has no PRIZE values below 1x.
How to Play
RTP
Turbo Storm Tempest has a theoretical RTP of 90.09%, or 90.26% when Hold and Win is bought for 75x the total bet in the base game. A bought round plays out like one that lands naturally.
Reel 2 Does the Collecting
With no paylines and no Wild, every win comes through a PRIZE COLLECTOR, which lands on reel 2 only. PRIZE symbols are confined to reels 1 and 3. A collector arriving with at least one PRIZE activates Turbo Storm and takes every PRIZE value on the reels. Instant Win values run from 0.1x to 15x, and three of them are below 1x, so a single small PRIZE can pay less than the stake.
Hold and Win Respins
A collector on reel 2 plus PRIZE symbols on both reels 1 and 3 opens Hold and Win with 3 respins. Nothing but collectors and PRIZE symbols drop from then on. Every collector holds its position until the feature ends, new ones included, and each PRIZE is collected as it lands. Either symbol landing returns the respins to 3. At the end, the game adds the collected total to the win.
Turbo Surge
Outside the feature, any collector or PRIZE may set off Turbo Surge at random, dropping extra collectors and PRIZE symbols onto the reels, always enough to start Hold and Win.
