Thunder Mega Sevens Bonus Buy Slot by Evoplay

Two accumulation paths feed into the same wheel. During base play, land 5 or more Bonus symbols anywhere on the reels and their values - random picks between 1x and 5x bet each - get totaled before the Wheel of Thunder spins. Free spins flip the logic: every Bonus symbol across all 10, 15, or 20 spins adds to one running sum, and the wheel fires automatically when the round ends. Even a single Bonus symbol during the feature is enough. The 50x, 75x, and 100x buy tiers map directly to 10, 15, and 20 free spins, so paying more buys a longer accumulation window rather than better odds per spin.

The wheel splits into eight sectors. Six are straight multipliers (x2, x3, x4, x5, x8, x12) applied to the Bonus total. The other two - x2+Respin and x3+Respin - multiply first, then respin the wheel with the respin sectors removed. So a x3+Respin landing followed by a x8 on the second spin turns a 10x accumulated total into 240x.

Neon lightning crawls down both sides of a dark metallic cabinet, hot pink glow bleeding through from behind. Cherries, lemons, bells, BARs, and three colors of sevens fill the grid against deep blue-purple. The base Thunder Mega Sevens version plays identically but without the buy option - scatters trigger free spins organically only. Wilds cover reels 2 through 5, leaving the first reel bare.
