- 4 Scatters — 5×4 field, 20 lines

Power-ups
When 2 Scatters appear, the player receives one of the following power-ups:

- x1 or x2 multiplier for expanding symbols
All multipliers are added together, increasing the potential winnings.
Expanding symbols
If an expanding symbol is part of a winning combination, it expands to cover the entire reel, resulting in an additional payout. These symbols are paid out on 10 lines, regardless of the size of the field.
Golden Bet
The Golden Bet feature allows you to increase your bet by 1.5 times, significantly increasing the likelihood of triggering the bonus game. This is a useful tool for players who bet on the bonus potential of the slot.

- RTP when buying a bonus: 96.2%
- Maximum bet per spin: $6,000
The number of Scatters when purchasing (3–5) does not affect the RTP — it remains the same.
