Lightning Storm has five bonus rounds, and every one of them starts from the wheel. Before each spin the game hands the bonuses out at random to the numbered segments, so a number that carried Hot Spot on one spin can carry the finale on the next. When the wheel stops, a Leaf pays one to one and ends the round, while a numbered segment sends the show into whichever bonus it was holding.
A number bet therefore resolves in two stages. The wheel decides whether a bonus happens at all, and the bonus decides how much it pays. That is why results on numbers feel so uneven compared with Leaf: you can wait several spins for a bonus, then receive a payout that covers a long run of small losses, or one that barely does.
Reference pages also describe a separate multiplier, roughly 2x to 50x, that can be attached to a number during the spin and that the bonus then starts with. It is the reason two Hot Spot rounds with similar boards can pay very differently. If you want the groundwork first, read how a Lightning Storm round works and return here, because this page assumes you already know the wheel and the Leaf.
Hot Spot is built around a wall of multiplier tiles, nine by twelve according to reference pages. A zone sweeps across the wall and doubles every multiplier it passes over, and your result is the value of the tile that counts for your round. Sources disagree on whether you pick the starting tile or the game does, so watch the on-screen prompt the first time it appears. The cap is quoted at 10,000x, yet one tracker's 90-day sample puts the typical Hot Spot at a median of 100x, a long way below the ceiling.
Monster Mash is the most mechanical of the five. Three reels, labelled head, torso and legs, each stop on a multiplier, and the regular values are added into a running total. Global multipliers behave differently: they multiply the total built so far, which means the order in which they land changes the payout. You make no choices during the round. The quoted cap is 10,000x, and the same tracker sample shows a median near 13x, so a modest result is far more common than a spectacular one.
Battery Charger reveals batteries one at a time on a conveyor. Green batteries add their multiplier to the total, while red ones remove charge and can end the round early through overcharging. When a global multiplier appears, it boosts everything collected up to that point, so the best moments come late in a run of green batteries. The cap is again 10,000x, with a sample median of about 15x. Of the three, it is the one where the round feels most like a build-up, because each reveal can either raise the total or cut the run short.
The fifth feature is Fireball, the name Evolution uses in its own announcement; a few reference pages call it Thunder Ball. A ball drops onto a floor of 149 pockets, and each pocket holds either a multiplier or a Double. Landing in a Double doubles the multipliers and releases the ball again, and the round ends when it settles in an ordinary multiplier pocket. Like the others, it is capped at 10,000x on third-party tables.
The finale is the Lightning Storm bonus itself. A billboard carries a set of regular multipliers and several global ones, one of three lightning strikes is chosen, and the values it touches decide the prize. It is the only round with a 20,000x ceiling, and it is also the rarest, a few percent of rounds in the tracker data used here.
A ceiling describes the best possible board, not a typical one. In the same 90-day sample the Lightning Storm bonus had a median near 90x and an average near 165x, while its largest recorded result was about 6,250x, still under a third of the maximum. Treat these as rough, since trackers disagree on totals, and plan stakes around the common outcomes: small and mid-sized bonuses arrive often, and the very large ones come rarely enough that a short session may never see one.
