Money Cart Slots: The Bonus-Only Relax Gaming Series
The Money Cart series strips each Money Train game down to its bonus. There are no paylines: every spin either lands bonus symbols or nothing, and three or more start the respins. The bonus comes far more often, but values are much smaller. Here's how the four games compare.

What a bonus-only slot is
In a Money Cart game you pay a normal bet per spin. Each spin shows only blanks, bonus symbols and special symbols. Land three or more bonus symbols and you get the familiar hold-and-respin round: 3 respins, and every new symbol locks and resets the count.
The series was designed for markets without bonus buys, such as the UK. Each Money Cart is a separate game in which any spin can trigger the respin round, and you pay for every spin as usual.
The trade-off is scale. AboutSlots estimates that Money Cart 4's symbol values are about 90% lower than in Money Train 4. The max wins are also far smaller than the originals.
How often? SlotCatalog puts the Money Cart 4 trigger at roughly one spin in ten, compared with about one in 387 for the Money Train 4 bonus.
The four Money Cart games
Each Money Cart mirrors one Money Train game and its special symbols. A festive cousin, Money Sleigh, is a Christmas reskin of Money Cart 3.

Money Cart vs Money Train: each game in detail
Same bonus, smaller numbers. If you want the full ceiling and a base game, the Money Train original is the closer fit. If you want frequent respin rounds and no paylines, Money Cart is the alternative.

Money Cart RTP and max win in dollars
The caps below are ceilings, not expected results. Most Money Cart rounds pay small amounts because symbol values are low.
| Game | RTP | Max win | At $0.20 | At $1 |
|---|---|---|---|---|
| Money Cart | 98% | 2,000x | $400 | $2,000 |
| Money Cart 2 | 98% | 5,000x | $1,000 | $5,000 |
| Money Cart 3 | 96% | 10,000x | $2,000 | $10,000 |
| Money Cart 4 | 96% | 15,000x | $3,000 | $15,000 |
Some sources quote max wins in coins (10 coins = 1x the bet). Figures here are in multiples of the bet.
A 98% RTP means that, in theory, $100 wagered returns $98 over a very large number of spins. Short sessions can land far above or below that. Check the RTP in each game's rules screen, because casinos can run different versions (see RTP versions).
Where to play Money Cart slots
Check that a casino is licensed in your country before you sign up. Open the rules screen to confirm the RTP version, especially for Money Cart 4 (see RTP versions). None of the four games has a bonus buy, so the UK versions play like the rest.

Play responsibly
Money Cart games start the respins often, but most rounds pay small amounts, so a run of bonuses can still add up to a loss. Treat gambling as paid entertainment, set a budget before you start and stop when it's gone.
