Grid / Symbols / Paytable
this slot plays a 5×3 grid with 20 paylines. Wins land left to right across matching symbols – 3 to 5 of a kind pay out. The paytable mixes classic arcade: triple 7s, bells, BARs, dollar signs, cherries. Premium symbols hit 2.6x to 10x stake for five of a kind; lower royals pay 0.5x to 1x. Wild substitutes for any pay symbol and pays the same as the highest-value triple 7s.
Above the reels sit three colored signs – green (Multi), red (Boost), blue (Collect) – each paired with a train. When matching-color bonus symbols land in the base game, that train collects them. Each collection rolls the dice on a bonus trigger. No other base game features exist. The slot leans hard on the bonus to deliver.
Hold / Win Bonus Round
Land at least one bonus symbol and the Hold & Win may trigger. Three bonus spins start the round. Three cash or jackpot symbols seed the grid randomly. Only blanks, bonus symbols, cash coins, and jackpot diamonds appear during the feature. Cash and jackpot symbols stick; the spin counter resets to 3 whenever a non-blank lands. Spin 3 consecutive blanks and the bonus ends. Fill the entire grid and unlock the 5000x Grand Jackpot – all other winnings are forfeited, as 5000x is the game’s hard cap.
| Jackpot Tier | Value |
|---|---|
| Mini | 10x stake |
| Minor | 30x stake |
| Major | 300x stake |
Cash symbols land with values from 0.2x to 5x stake. Hot Cells can appear on the reel area, boosting odds of landing a cash or jackpot symbol.
Three Cash Features
Depending on how many bonus symbols triggered the bonus, you activate 1, 2, or all 3 cash features in the same round. Combine them or run them solo – the bonus adapts.
| Feature | Effect |
|---|---|
| Cash Boost (Red Train) | Adds random value to red bonus symbol; increases each time a new red bonus symbol lands |
| Cash Multi (Green Train) | Boosts 1 to 3 cash or jackpot symbols by x2, x3, or x5 |
| Cash Collect (Blue Train) | Collects value from all present cash and jackpot symbols |
The bonus round continues until 3 consecutive blank-only spins or grid fill. Trigger all 3 features and the slot scales up pressure and payout potential – but coin values alone rarely push toward the 5000x ceiling without heavy multiplier stacking and jackpot symbols.
Golden Bonus / Express Feature
A golden bonus symbol can land in the base game and awards 3 bonus rounds played back-to-back: Cash Boost first, then Cash Multi, then Cash Collect. Each round runs independently with its own feature active. Landing golden bonus symbols during an active bonus reactivates up to 3 bonus symbols already on the grid, extending the round.
The Express Feature randomly triggers during base game spins, awarding the bonus round with 1-2 cash features, a golden bonus round, a big win, or an improved base game win. It is a safety valve – when the base game feels flat, the Express can jolt the session toward the bonus.
