Thunderstruck Wild Lightning

About this Game

  • This is a 5 reel 4 row video slot game.

  • The objective of the game is to spin the reels so the symbols land in different combinations.

  • Winning combinations are highlighted on the reels and a payout is awarded.

Payline Rules

  • This game includes 40 paylines.

  • The number of paylines played is fixed.

  • A payline is a pattern of adjacent symbol positions that runs in a line across the reels.

  • A win is awarded when matching symbols land adjacent to each other on a payline.

  • Payline wins run from left to right, starting from the first slot reel.

Bet Rules

  • Each spin played costs a total bet amount.

  • The initial bet is the number of coins multiplied by the coin size.

  • The total bet is based on the initial bet placed, multiplied by the cost of the paylines played.

Payout Rules
