Thunder Mega Sevens Slot by Evoplay

Every Bonus symbol that lands on the reels carries a random value between 1x and 5x total bet. In the base game, filling five or more reel positions with Bonus symbols triggers the Wheel of Thunder directly, summing all values before the spin. During free spins, the mechanic shifts - Bonus values accumulate across the entire round, building a total that feeds into a guaranteed wheel spin once the last free spin ends. Even a single Bonus symbol during the feature is enough to trigger it.

The wheel itself has multiplier sectors ranging from x2 up to x12, applied to the accumulated Bonus total. Two special sectors combine a multiplier with a respin: x2+Respin and x3+Respin. When a respin sector hits, the total gets multiplied first, then the wheel spins again with only pure multiplier sectors remaining. That double multiplication is where the 3,003x ceiling sits.

Scatters trigger 10, 15, or 20 free spins depending on count (3, 4, or 5). Additional scatters during the round retrigger more spins. Wild appears on reels 2 through 5 only, substituting for all regular symbols but not for Scatter or Bonus.

The paytable leans into classic fruit machine territory. Triple Seven tops the regular payouts at 15x for five-of-a-kind, followed by Double Seven at 8.5x. BAR and Single Seven both sit at 6.5x, while the four fruit symbols (cherry, lemon, bell, orange) share identical payouts at 3x for a full line. This is the base version without a buy bonus option - free spins trigger organically through scatter landings only.
