Most symbols pay from 3 of a kind, except for the two top symbols that pay from 2.



2. Stacked symbols

Symbols can land in stacks, occupying the entire reel.

3. Wild symbol

Wild substitutes for any symbol except Scatter and has no value of its own.

4. Wild multiplier

Wild can have a multiplier of x2 and x3.

If the winning combination contains several Wilds with multipliers, the multipliers are multiplied with each other.

Bonus game mode

  1. Buy Bonus

The player can buy the bonus game at any point.

The purchase price is equal to x100 of the bet.

For example: a $1 bonus game costs $100.



2. Regular trigger

The bonus game starts when 3, 4, or 5 Scatter symbols appear in the main game mode.

The number of free spins depends on the number of Scatter symbols:

  • 3 Scatter symbols – 10 free spins
  • 4 Scatter symbols – 15 free spins
  • 5 Scatter symbols – 20 free spins

4. Collect tokens

Before free spins start, the accumulation of tokens is triggered. Tokens may have values from 1 to 25.

The initial number of spins is 3, and then each new token returns the number of spins to the original value.



5. Free spins

When free spins are triggered, the accumulated tokens are displayed on the meter above the game area. Newly accumulated tokens are also added there.

Collected tokens turn medium-value symbols and one high-value symbol into the top symbol:

  • 120 – third medium-value symbol
  • 200 – fourth medium-value symbol
