Game Rules for Thunderstruck II

Summary of official Game Rules:

  • Thunderstruck II is a five reel, 243 pay way and 300-coin slot machine.
  • Regular symbols are all symbols on the reels that do not have a bonus feature but complete regular winning combinations on enabled pay ways.
  • Matching symbols must be next to each other on an enabled pay way.
  • Regular winning combinations pay out from left-to-right, so one symbol must be displayed on the first slot reel. A symbol combination starting from the second, third, fourth or fifth slot reel does not pay out.
  • Regular payouts depend on the number of coins you bet per spin. For each spin, the bet amount you choose is automatically multiplied by the bet multiplier.

  • Two or more symbols must appear anywhere on the reels to create a win.
  • This symbol cannot be substituted by the wild, multiplier symbol.
  • Scatter wins are calculated by multiplying the scatter symbol combination payout by the total number of regular coins bet.
  • Scatter payouts depend on your total bet.
