Game Rules

The respin continues if at least one symbol position becomes part of a new winning payline or a coin win is formed.

After each game round, the multiplier trail resets, and random multipliers appear on it. With each new winning combination, the multiplier trail shifts one position to the left.

When a winning combination is formed, the value of the leftmost wagon on the multiplier trail is added to the value of the global multiplier bell.

At the end of a game round, the total win—excluding coin wins—is multiplied by the global multiplier bell value.

The global multiplier bell value resets after each game round.

Wild symbols substitute for all paying symbols, except coins.

If a winning combination consists solely of Wild symbols, the payout is calculated based on the highest-paying symbol.

Bonus Game

In the bonus game, the Wild multiplier meter has 10 levels.

At the start of the bonus game, the Wild multiplier meter is at level 1.

With each new bonus spin, the Wild multiplier meter level increases by 1 until it reaches level 10.

Wild symbol

Each Wild symbol that is part of a winning line takes on the value of the Wild multiplier meter and transforms into a Wild with a multiplier.

Each Multiplier Wild adds its multiplier value to the global multiplier bell or to one of the wagons on the multiplier trail. The value is added first to the bell, and then to the wagons from left to right.

After the multiplier action is performed, the Multiplier Wild symbol locks in place and transforms into a regular Wild.

Multiplier Wild meter values: Bonus game:

Level 1: +2
Level 2: +3
Level 3: +4
Level 4: +5
Level 5: +6
Level 6: +7
Level 7: +8
Level 8: +9
Level 9: +10
Level 10 and above: +25

The values ​​of all winning coins are summed up, and the resulting total is multiplied by the bet.

Coins

Coin symbols can appear on any reel.
Coin symbols do not participate in paylines.

There are three value ranges for coins: gold, silver, and bronze.

If at least 3 coins land anywhere on the reels during the base game or bonus game, all these coins are activated: their values ​​are revealed, and the winnings are awarded.

Coin wins are paid out separately before the global multiplier is applied to the total win.

Wilbur’s Coin Fever

The coin collection feature accumulates coins and can trigger the Wilbur’s Coin Fever mode.

Wilbur’s Coin Fever is a bonus game played on a grid of 2–5 rows that begins with 3 spins. Any symbol that lands remains on the reels until the Wilbur’s Coin Fever mode ends.

At the start of the mode, the bottom three rows are covered by a grid.

Symbols covered by the grid are inactive; they do not contribute to forming wins and have no impact on the game.

The main reel area, consisting of two rows, is located above the grid.

All symbol positions in the main area are active. Symbols revealed when the grid is removed also become active and can contribute to forming wins or otherwise affect the game.

If at least one symbol lands on the active reels, the spin counter for the Wilbur’s Coin Fever mode resets to its initial value.

The Wilbur’s Coin Fever mode ends when the spins run out.

If symbols fill all positions on the game grid, the coin game concludes and winnings are calculated.

The total coin win is displayed upon the completion of the Wilbur’s Coin Fever mode.

During Wilbur’s Coin Fever, the Collector symbol collects the values ​​of all symbols on the grid at its position and then transforms into a coin.

During Wilbur’s Coin Fever, the Distributor symbol adds its value to the value of every symbol on the grid and then transforms into a coin.

During Wilbur’s Coin Fever, up to 3 Pressure symbols can land on rows 1 – 4. Each one unlocks 1 row – increasing the number of active rows to a maximum of 5 – and then transforms into a coin.

Coin symbol values ​​in the 5th row are multiplied by 2 each time at least one symbol lands in that row. The multiplication occurs after all feature symbols on the game board have performed their actions.

If multiple feature symbols land during a single spin, they perform their actions in the following order: Pressure symbols, Collector symbols, and Distributor symbols.

Feature symbols perform their actions from top to bottom across rows and from left to right across columns.

3 bonus symbols trigger a bonus game with 10 bonus spins.
4 bonus symbols trigger a bonus game with 15 bonus spins.
5 bonus symbols trigger a super bonus game with 15 bonus spins. The starting level of the Wild multiplier meter is 5.

Bonus games cannot be re-triggered.
A bonus symbol appearing during a bonus game awards 2 additional bonus spins.
Winnings are paid out at the end of the bonus mode.
The bonus game ends when the bonus spins run out or the win limit is reached.

Information

All winning combinations, except for coin symbol combinations, start on the leftmost reel and pay from left to right on adjacent reels, with no gaps between the columns.
Only the longest winning combination is paid out on each active payline. The active payline is determined by the longest winning symbol combination formed during the game round.
The game features three modes: standard, bonus, and Wilbur’s Coin Fever. Every payline win or coin win triggers a respin in both the base game and the bonus game.
