Reels, Paylines, or Grid Mechanics

Thunder Coins XXL uses a 6×5 grid format with 50 fixed paylines. The game does not support variable payline options but offers an Autoplay feature to speed up gameplay for experienced players.

The slot’s core mechanic revolves around the use of Wild symbols (explained in detail below), which can substitute any symbol, including high-value ones, to create winning combinations. Players should note that some paytable entries require multiple consecutive wins or specific symbol combinations, adding strategic depth to the game.

The slot’s gameplay is divided into several phases:

• Regular Spins : These are standard play rounds where players bet on a fixed number of spins (1-10) using coins worth 0.01-5 units each.
• Free Spins : Triggered by three or more Scatter symbols, which activate various free spin options (see section below).

Wild Symbols

There are two types of Wild symbols in Thunder Coins XXL:

• Standard Wilds : Replacing any symbol except Scatters, these appear on reels 2-5 and contribute to regular wins.
• Thunderbolt Wilds : Exclusive to the highest-paying Zeus’ lightning bolts, they become sticky when a player lands two or more of them. During each free spin following that landing, all Thunderbolt symbols will move one reel in either direction.

Bonus Features and Bonus Rounds

The slot offers five bonus features:

1. Scatters : Triggers free spins based on the number collected:
   • Three Scatters: Awards ten free spins with a multiplier starting at x2 (x3-10 possible).
