After you score a win, the squares behind the winning symbols turn gold. If a Rainbow Symbol appears on the reels during the cascade following your win, the Golden Squares feature triggers and you'll be awarded Bronze, Silver or Gold coins, and the opportunity to land a Pot of Gold or Four-Leaf Clover Symbol.
All coins act as multipliers, offering varying payouts that are multiplied against your bet. Bronze coins payout 0.2x, 0.5x, 1x, 2x, 3x, or 4x your original stake, whilst Silver coins payout 5x, 10x, 15x or 20x. Gold coins are the highest-paying coins of the three, offering payouts of 25x, 50x, 100x, 200x or 500x your bet.
If the Four-Leaf Clover Symbol appears on a Golden Square, it triggers a multiplier of 2x, 3x, 4x, 5x or 10x on the coins and any Pot of Gold Symbol’s total value, only if the symbols land in adjacent positions.
Pot of Gold Symbols are the last to activate and store the total value of both coins and Pot of Gold symbols from top-to-bottom and from the left-most reel.
This feature continues until no more Pot of Gold Symbols land and at the end of the spin, all coins and Pot of Gold values are added together and multiplied against your original stake, awarding you the total amount.
