If you’re comparing prices before spending anything: buy-feature prices across the series span from 10x (Money Train 5’s cheapest Super Charge tier) to 2,000x (its priciest). Money Train, Money Train 2 and Money Train Origins Dream Drop each run one fixed price; Money Train 3 and Money Train 4 offer multiple tiers. The table below has every option; the sections after it cover what each buys and what it costs over time.

What each option actually buys
Money Train — 80x for a straight Money Cart round
One option only: pay 80x your stake for a 20-position Money Cart round with three respins — the same round the three base-game scatters would trigger naturally. No tiers, no starting extras. Full context on the Money Train review.
Money Train 2 — 100x for the same odds as landing it naturally
One option, at 100x, for the same standard-three-respin round you’d reach naturally; the grid can still grow to seven reels, and the +500x full-grid bonus is just as available. More in the Money Train 2 review.
Money Train 3 — four tiers, from a head start to a loaded round
The most flexible pricing in the series: 20x buys one starting respin already banked, 50x buys two, 100x is standard, and 500x starts the round with a persistent special symbol already on the grid. Pricing context on the Money Train 3 review.
Money Train 4 — standard or persistent-start
Two options: 100x for a standard round, or 500x for one that opens with a persistent symbol already placed — the same idea as Money Train 3’s top tier. See the Money Train 4 review.
Money Train Origins Dream Drop — 80x, but only in one version
The 80x buy exists only in the non-Dream Drop configuration. Run the jackpot-linked version instead and there’s no buy at all — the Money Cart round can only trigger naturally, from three or more bonus symbols. Details on the Money Train Origins review.
Money Train 5 — six Super Charge tiers, plus Enhanced Spins
Money Train 5 spreads its buy feature across six named tiers instead of one flat price: Bonus Reels and Ultra Bonus Reels (10x/25x) are the entry-level pair; the remaining four climb from 100x to 2,000x for richer starting positions. One published source also lists a lower 1.5x tier ahead of these six, so check the exact menu at your casino.
It also offers Enhanced Spins — a 50% bet increase that doubles the bonus-trigger chance, rather than a one-off purchase. See the Money Train 5 review for how the bonus plays out.
The honest maths: is buying the bonus worth it?
Buying the bonus doesn’t change the odds of what happens once you’re inside it — only how you got there. The only published average bonus size in the series belongs to Money Train 5, at roughly 95.6x the stake — close to break-even against the 100x standard “Free Spins” price, which is what you’d expect from a fairly priced feature, not a signal that buying is smart. An average hides everything that matters: some rounds pay a fraction of the buy price, others pay hundreds of times more, and there’s no way to know which you’ve bought until the respins stop.
For the other five games, no average bonus size is published, so the price can’t be measured against a typical return — only against the RTP-with-buy figures on our RTP and volatility guide, which describe millions of purchases averaged together, not one. What buying reliably changes is speed: a 500x purchase spends in one click what 500 base-game spins would take to wager. For how a purchase compares with the series’ biggest payouts, see our max win guide.
Availability: buy features aren’t switched on everywhere
Bonus buy features aren’t available in every country or at every casino. Some licensing regimes require these options disabled entirely, regardless of what the maths model supports, so a casino under one of those licences may show the buy menu greyed out or missing even though the feature exists. Check the in-game menu rather than assuming the option is there — availability depends on your location and the operator’s licence, not on which game you’ve picked.
Where these prices come from
The prices above come directly from each game’s buy-feature menu, as documented in the maths model summaries published at release. Menu wording occasionally differs between casinos — some list the multiplier, others show a cash amount from your current stake — but the underlying multiple is fixed by the game itself, not the casino. For the full series in one place, see the Money Train slots hub.
FAQ
Which Money Train game has the cheapest bonus buy?
Money Train 5’s Bonus Reels option, at 10x — the lowest price in the series. Money Train 3’s cheapest tier, 20x for one pre-loaded starting respin, is lowest among the classic-format games. Price alone isn’t directly comparable across games, since it doesn’t reflect each game’s own bonus value.
Which is the most expensive?
Money Train 5’s Ultra Super Free Spins, at 2,000x — well above Money Train 3 and Money Train 4’s top tier of 500x, and the highest price in the series.
Does buying the bonus improve my odds of a big win?
No. Buying the bonus takes you straight into the round; it doesn’t change what that round pays out. The respins, multipliers and special symbols behave exactly as they would if triggered naturally from the reels.
Can I try the bonus buy in the demo?
Most Money Train demos include a working buy menu, so you can see what each price gets you before spending real money — see our demo hub for all six games. Demo credit has no cash value.
Is the bonus buy available at every casino?
No — some licensing regimes require buy features switched off, so the option may not appear even though the game supports it. Check the buy menu at your chosen casino; our where to play guide covers the rest of what’s worth checking before you deposit.
