Welcome! I would start with Money Train 2 Review
https://money-train-2.com/ because it explains the game from the base reels to the Money Cart feature in plain English. You can see how the 40 fixed paylines work, what triggers the main bonus, and why the Collector, Payer, Sniper, and Necromancer have different roles. The page also separates normal spins from the more complex respin action, so you can learn the flow before risking money. Try the demo first and use virtual credits until you can follow every effect. Real-money play should be legal in your area, for adults only, and limited to a fixed entertainment budget.
