About Nikola Tesla’s Incredible Machine
Powered by Yggdrasil Gaming (I note collaborations such as this becoming a common trend with online slots these days), Rabcat has tooled up Nikola Tesla’s Incredible Machine with a base game of five reels and twenty-five paylines to spark wins from spins. The low-ranking symbols on those reels comprise four Royals (A to J), whilst a capacitor, lab goggles, and a stopwatch amp up the rewards possible from a payline win. The legendary Tesla himself is also present with a dual role as a high-pay symbol in this own right, whilst offering Wild assistance to all other regular symbols to switch on surprise wins. The sole symbol he can’t substitute for is this game’s Bonus Scatter, which is the catalyst to putting this slot’s bonus features under my microscope . . .
Staying with the Incredible Machine’s base game, the middle reel should bear close scrutiny since filling it with matching instances of any regular symbol with engage the Energy Burst Feature. The low-pay Royals trigger three bonus spins, whereas the three higher pay symbols up that to five spins. Common to all spins racked up in this Energy Burst is the application of a random reel modification to boost the paying power. This can be either:
- Wild Substitution – a regular symbols is chosen at random to act as an extra Wild during all bonus spins.
- Reel Clone – three randomly chosen reels from the five are locked in sync for all the bonus spins.
- Exploding Wild – two or three positions are allocated as Sticky Wilds for all the bonus spins.
Moving our attention to the bonus effects of the previously mentioned Scatter this powers up eight, ten or twelve free spins should three, four or five Scatters land in view during base game spins. Naturally the Incredible Machine bolts on some extra zap to these free games, starting with engaging a ‘both ways’ win rule to enable winning combinations to start from reel one or reel five. Next you’ll find a Sticky Wild is popped onto the central position of reel three to kick-start another powerful boost to your chances. Finally reels one and five add a Level Up scatter to their inventory of symbols, and whenever this lands it will add another Sticky Wild to play for all remaining free games, maxing out at five if you attract luck like an electromagnet attracts iron!
