Key Features and Mechanics

5x3 reels, 5 paylines, pays left to right.
Star Wild: Substitutes for all symbols except Cash (Golden Coins), Jackpot, and Cash Train.
Golden Coin Cash Prizes: Coins show instant cash values such as 1x, 2x, 3x, 4x, 5x, and 10x. These are only awarded when a Cash Train is on the reels to collect them.
Supersonic Multipliers: On every spin, 1–3 overlay multipliers (x2, x3, or x5) appear on random positions. All overlays show the same value per spin. If a symbol, coin, or jackpot under an overlay forms a win or gets collected, the multiplier applies. Multiple active overlays add together before applying.
Cash Train Collect: Up to 3 Cash Train symbols can land on the middle reel. Each Cash Train collects all visible Coin cash prizes that spin.
Hold & Win Bonus: Triggered when Golden Coins or a Cash Train add enough symbols to reach at least 1 Cash Train plus a total of 4 Golden Coin/Jackpot symbols cumulatively, or when 4 Golden Coins land at the same time as a Cash Train.
Hold & Win Flow: Starts with 3 free spins; landing a Coin, Cash Train, or Jackpot resets the counter to 3. Cash Trains lock in place until the feature ends. All Coin and Jackpot prizes that land are collected once by each locked Cash Train and paid at the end. The feature can end early if all 3 Cash Trains cap out their collection limit.
Jackpots: Four fixed prizes can land during Hold & Win when a Cash Train is present:
- Mini: 15x stake
- Minor: 50x stake
- Major: 150x stake
- Grand: 1000x stake Each Jackpot can appear once per spin (except when added upon activation of the feature).

How Supersonic Multipliers Work

Between 1 and 3 overlay multipliers (x2, x3, or x5) are guaranteed to appear on every spin.
All overlays show the same value on that spin.
If a winning combination, Golden Coin collection, or Jackpot prize sits under an overlay, the multiplier activates and applies to the payout.
If multiple overlays affect the same outcome, they add together first, then multiply the win or collected amount.

Hold & Win With Locked Cash Trains

Trigger conditions: Coins and/or a Cash Train can activate the mode. The feature ensures you start with at least one Cash Train and a cumulative total of four Coins/Jackpot symbols.
Respins: Begin with 3; each new Coin, Cash Train, or Jackpot resets to 3.
Locked Trains: Cash Trains stay until the end, collecting each Coin/Jackpot prize once per train. This creates stacking collections, as multiple trains can pick up the same prize.
Payout: All collected amounts are awarded when the feature finishes.
