Wonder Train online slot game
Wonder Train is the latest slot off the conveyor belt at Elk Studios, and while it is not as feature-heavy as many other titles in the studio's portfolio, it still packs quite a few. The medium variance slot has 20 paylines across a 5x4 grid, and delivers respins after every win, global multipliers, a multiplier track, and two main bonus games.
Wonder Train Slot- Right for you?
- Play this if: You prefer slots that give you the chance to land multiple wins from a single spin via a chain reaction of multiplier-boosted winning combos.
- Skip this if: You’re after a more dynamic reel mechanic or want more volatility from your spins.
- Bankroll minimum: As Wonder Train has a medium variance and a 0.20 minimum stake, we’d suggest starting a session with a bankroll of no less than €10. That gives you at least 50 spins.

Theme and First Impressions
The big and bold visuals of Wonder Train instantly catch the eye, with the different shades of greens, purples, and blues really allowing the reels, symbols, and background to pop. The steam train is the center of the show, with its engine set to the left of the reels and its different carriages stretching behind them and to the right.
To compare with another train-themed slot we really enjoy, Relax Gaming’s popular Money Train 5 also uses the engine and train cars as the centrepiece, although the reels on that slot are within one of the passenger cars, whereas here, they’re set in front of them.

How Wonder Train Plays - Base Game
Wonder Train utilizes a 5x4 reel setup that features 20 fixed paylines. As a result, landing wins requires three or more matching symbols across those winways. A Multiplier Track and Global Multiplier Bell above the reels can boost payouts, while wild symbols can also appear to help create paying combinations. Furthermore, every win is followed by a respin with winning symbols locked in place and continues until no further wins land.
Of the eight regular symbols, the Gold Bars with a top payout of 2.5x are what you’ll want to see most often. A clock, suitcase, and oil are the remaining premiums, while the lower pays will come from the four playing cards, all rewarding up to 0.25x the stake.
- With a 1 EUR bet, the paytable looks like this:
| Symbol | 5 Matches | 4 Matches | 3 Matches |
|---|---|---|---|
 | 2.50x | 1.50x | 1.00x |
 | 0.75x | 0.50x | 0.30x |
 | 0.50x | 0.30x | 0.20x |
 | 0.40x | 0.25x | 0.15x |
 | 0.25x | 0.15x | 0.10x |
 | 0.25x | 0.15x | 0.10x |
 | 0.25x | 0.15x | 0.10x |
 | 0.25x | 0.15x | 0.10x |
Bonus Features and Free Spins
The quality and variety of bonus features are often the selling point on Elk Studios slots, in our opinion, and we can confirm that’s the case again on Wonder Train. The slot delivers multipliers, cash prizes, two bonus games, and a selection of special bets and feature buys.
Multiplier Track & Global Multiplier Bell
Sitting above the reels, the Multiplier Track moves one place left after every spin, with the leftmost train car and its current multiplier value being added to the Global Bell Multiplier following a win. That value applies to the total win once calculated at the end of the spin.
Coins
When at least three Bronze, Silver, or Gold coins land anywhere in view, their values are revealed and paid. Just note that the Global Multiplier does not apply to these scatter wins.
Wilbur’s Coin Fever
While the prizes are welcome, it is the chance for these coins to trigger the Wilbur’s Coin Fever bonus that appeals the most. Once triggered, you receive three spins on a 5x5 grid that starts with just two of the five rows unlocked. The fifth of these is a locked multiplier row. Whenever a new coin lands on the reels, it’s collected and your respins are reset.
Along the way, Clock symbols can land, which will unlock the next row down. On top of that, collectors combine and pay out all the values on the screen, and dealers add their values to all the coins on show.
Free Spins Bonus
Spin in 10 or 15 free spins featuring a 10-level progressive wild meter that unlocks multipliers ranging from 2x to 25x. These are all applied to winning combinations created by wild symbols and are also added to the Global Multiplier Bell, which does not reset between spins.
Special Bets
The Bonus Hunt and Mega Hunt ante bets increase your chances of triggering the free spins bonus and cost 2.5x and 5x the stake, respectively. It’s also possible to buy straight into the Wilbur’s Coin Fever bonus and the regular free spins bonus or super free spins round, with the multiplier meter starting at level 5 for 100x and 250x.
What to Expect When Playing Wonder Train Slot
From our experience testing Wonder Train, you can expect spins with quite a bit going on. Respins lock wins in place, multipliers can increase, and long chains of wins can quickly build up your total payout.
Win Potential and Volatility
The maximum win is 10,000x, which isn’t the largest by any means but is more than adequate. The winning potential on the slot mainly comes down to the global multiplier and the respins that can allow it to grow during the base game and free spins bonus. A streak of wins during our testing regularly saw it reach over 50x and, on a couple of occasions, reached more than 150x.
Bet Range and Who It Suits
The betting range available on Wonder Train is not the widest, but it should suffice for both budget players and high rollers. A €/$/£10 bankroll should be enough for more casual players to enjoy a session, especially as the slot carries a medium variance that should see more frequent wins. As for high rollers, the buy bonus features may appeal if you feel the maximum bet is not high enough for your liking.
Mobile Performance
We tried the Wonder Train slot on a variety of smartphones, both Android and iOS, and have no real complaints about performance. The slot usually loaded up quickly and apart from one time when our internet connection dropped, it ran perfectly on all devices.
How Wonder Train Compares - Other Slot Titles
| Slot | Provider | RTP | Max Win | Main Mechanic |
|---|---|---|---|---|
| Money Train 5 | Relax Gaming | 96.10% | 100,000x | 5x4 with 40 fixed paylines, nuclear wilds, free spins with stations, bonus reels, and Hold & Win |
| Wild West Gold | Pragmatic Play | 96.51% | 10,000x | 5x4 grid with 40 fixed paylines, multiplier wilds, sticky wilds and a free spins bonus |
The Money Train series is what we thought of first when opening Wonder Train, which is mainly because of the theme and certain aspects of the design. They’re very different titles, though, with Relax Gaming's release far more volatile and packed with a wider variety of features and bonus games. Plus, it has a huge 50,000x maximum win in regular mode and 100,000x in Ultra mode, so it will certainly appeal to high rollers.
As for Wild West Gold, Pragmatic Play’s slot is all about multipliers and sticky wilds, and is a more generic-style slot. It’s great if you’d rather have more straightforward spins compared to Wonder Train.
Final Verdict - Is Wonder Train Worth Playing?
There’s a lot to unpack when you first start spinning the Wonder Train reels, what with Multiplier Reels and Global Multipliers and respins popping off after every win. It doesn’t take too long to get a feel for the slot, though, and when those multipliers start reaching the higher numbers, your sessions have a good chance of proving profitable. It’s also nice to have a couple of different bonus features to trigger, although we only landed the free spins bonus during our 200-spin test.
