Game Rules

Wild Symbol

Appears only on reels 2, 3, and 4. It substitutes for all symbols except the coin symbol. When a wild symbol lands anywhere on reels 2, 3, or 4, it expands and turns into a wild symbol that covers the entire reel. At least one winning line must pass through it to expand and cover the entire reel. If a wild symbol lands on reel 3, it is awarded a 2x multiplier.

Coin Symbols

Appears in both the main game and the bonus game. When at least 6 coin symbols land in the main game, the Hold ‘n’ Win bonus game is triggered. If the Hold ‘n’ Win bonus game is not triggered, coins do not count towards winnings. All coin values ​​can be multipliers: 1x, 2x, 3x, 5x, 7x, 10x, 12x, 15x, 25x, 50x, 100x.

Expanding Wild with Multiplier

The Wild symbol can expand to cover an entire reel, depicting a full-sized Griffin character. The feature is triggered when the Wild symbol lands anywhere on reels 2, 3, or 4, and if at least one payline passes through it. When the Wild symbol lands on reel 3, it is awarded a 2x multiplier.

Hold and Win and Coin Multiplier

The feature is triggered when 6 or more coins land anywhere on the reels. At the start of the game, 3 re-spins are awarded, featuring only coin symbols.

When the Hold & Win feature is activated, coin symbols from the main game remain fixed in their positions during the awarded re-spins. Each time a new coin symbol lands, the re-spin counter resets to 3, and if no coin symbol lands, the counter decreases by 1. The bonus game ends when all awarded re-spins are completed or when coin symbols fill the entire game board.

During the Hold & Win feature, a random multiplier can land on any spin and in any position. Available multiplier values ​​are: 2x, 3x, 10x. A multiplier can land on a coin symbol or an empty position only once. If it lands on a coin, it sticks to that coin. If it lands on an empty position, it becomes “sticky” as a potential multiplier until a coin symbol lands in that position or the re-spins are completed.

At the end of the function, the multipliers are applied to the corresponding coin values, after which the coin values ​​are summed. Finally, if applicable, the progress bar multiplier is added to the total win amount.

Hold & Win Progress Bar

The progress bar helps track the number of coin symbols collected during the Hold & Win feature. It starts with 6 coin symbols, and as additional symbols appear, the bar increases to display the total number of coin symbols on the reels. When 15 coin symbols appear on the reels, the total win is doubled. When 20 coin symbols appear on the reels, the total win is 5x.

At the end of the feature, the total number of coins will be multiplied by the multiplier from the progress bar. All coin values ​​are multiplied by the active bet.
