About this Slot
Thunderborne from Jackslot Games is a 3-reel, 5-row mythology, action and adventure slot with 15 paylines, an RTP of 96%, high volatility and a maximum win of 5,000x.
Wild Strike activates when a glowing frame lands on the reels. When a wild hits the frame, the frame copies to all wilds present, triggering lightning that transforms additional symbols into wilds with multipliers between 3x and 10x. Wild Strike guarantees a minimum payout of 5x the bet.
Three Bonus symbols trigger the free spins feature. Base Free Spins awards 10 spins with 2x multipliers on wilds. Super Free Spins grants 20 spins with 3x multipliers on wilds. Retriggers during free spins add extra spins, up to a maximum of 30 total spins.
The Activate Wheel toggle converts Free Spins into a Bonus Wheel feature. The Bonus Wheel applies multipliers of 3x, 4x, 5x, 7x or 10x to wilds. These Bonus Wheel multipliers stack with any Wild Strike multipliers earned during the feature.
Buy Bonus Wild Boost costs 3x the bet and activates Wild Boost for the bonus feature. Activate Wheel costs 3x the bet. Wild Boost plus Activate Wheel costs 6x the bet. Buy Bonus costs 100x the bet. Buy Wheel Bonus costs 150x the bet. Buy Super Bonus costs 300x the bet.
