All Aboard Slots Review - Hold & Spin Trains, Free Games & Progressive Jackpots

All Aboard Slot - Editor's Comment

All Aboard is one of those Konami series that has quietly built a following on casino floors without needing a film licence or a celebrity tie-in. The appeal is the bonus. The base game is a standard five-reel affair, but the All Aboard feature turns the screen into a grid of spinning positions where gold coins and trains can pay again and again. That repeated collection mechanic is what separates it from a generic Hold & Spin clone.

The trade-off is patience. The feature needs six or more train symbols, and the free games scatter only appears on reels two, three and four in the Dynamite Dash version, which makes triggering anything feel like work. Players who want constant action may find the base game slow. Players who enjoy the build-up to a volatile bonus will find plenty to like.

One important point for Irish readers: All Aboard is primarily a land-based and multi-game cabinet series. The Dynamite Dash rules we reference come from Loto-Québec's published game rules, which describe a 50-line, five-reel game with a free game feature and a bonus game feature. Online availability in Ireland depends on whether a licensed operator carries the Konami iGaming version, and that varies by operator and jurisdiction.

What We Liked

• The All Aboard feature pays repeatedly as new trains land, rather than holding everything until the end.
• Multiple themed versions give the same core mechanic different free games twists.
• The rules are clearly published, including the Grand Jackpot condition.
• Five jackpot levels (Mini, Major, Maxi, Mega, and Grand) add a second layer of potential.

What is the All Aboard Slot?

All Aboard is a Konami slot series built around a train theme. The base game uses a five-reel, three-row layout, and the Dynamite Dash version is a 50-line game with a free game feature and a bonus game feature, according to the published Dynamite Dash rules. The series also appears as a multi-game edition on Konami's DIMENSION 75C cabinet, described by Konami Gaming as a multi-game edition of the popular All Aboard series with a 1-level linked progressive and 4-level non-incrementing jackpots.

The series includes several versions, each with a different theme and free games behaviour. Known versions include Dynamite Dash, Go West, Masked Warrior, Piggy Pennies, Charms of the Orient and Mighty Panda. The core All Aboard feature is shared, but the free games feature differs by version. That means you cannot assume the free spins from one version apply to another.

For Irish players, the practical question is which version, if any, is available through a licensed online operator. Konami's iGaming platform is listed among the company's supported platforms, but individual operator catalogues vary. Always check the specific game version and its published rules before playing.

All Aboard Slot Machine At A Glance

The table below reflects the Dynamite Dash version as described in the published Loto-Québec rules, plus the multi-game cabinet details from Konami. It does not represent every version in the series.

The Dynamite Dash rules state that all wins are shown in currency except credit prizes. The values for the Mega, Maxi, Major and Mini bonuses scale with denomination and credits bet. The chance of winning the Grand Jackpot changes with the credits bet per line, and the Grand Jackpot may be awarded randomly at the end of any bought game.

Konami's multi-game listing describes a 1-level linked progressive with 4-level non-incrementing jackpots, and notes two options for linked progressive reset values. That is a cabinet-level description, not a full paytable, so treat it as context rather than a complete specification.

All Aboard Slot RTP, Payout and Volatility

We do not have a verified RTP figure for the All Aboard series from an official Konami or regulator source. Third-party review sites list figures, but those can vary by version, jurisdiction and cabinet configuration, and we will not present an unverified number as fact. If you see an RTP quoted for All Aboard, check whether it refers to the exact version and market you are playing.

What the published rules do tell us is how the payout structure works. In Dynamite Dash, line pays occur on adjacent reels starting with the leftmost reel, and only the highest winner is paid for each winning combination. All wins are added. The Miner symbol appears on reels two, three, four and five only and substitutes for all paytable symbols except Dynamite and Train.

Volatility is generally described as high, with the All Aboard feature requiring six or more Train symbols and the free games scatter appearing on only three reels in Dynamite Dash. That combination tends to produce long base-game stretches between features.

Remember that RTP is a long-run theoretical average, not a prediction for any session. A high-volatility game can pay nothing for a long time and then produce a large feature. That is the nature of the maths, not a sign that a win is due.

How to Play All Aboard

Playing All Aboard follows the same basic steps as most five-reel video slots. The specific rules below are from the Dynamite Dash version.

1. Choose your denomination and credits per line. The minimum bet varies by version and denomination.
2. Check the paytable on the game interface. The rules state that prizes are paid in accordance with the payout table available on the game interface.
3. Confirm your total bet before spinning. The rules note that the player is responsible for ensuring correct credits are registered before play.
4. Spin the reels. Line pays occur on adjacent reels starting from the leftmost reel.
5. Watch for three Dynamite symbols to trigger the free games feature, and six or more Train symbols to trigger the All Aboard feature.
6. During free games, the number of Miner symbols is increased, and the All Aboard feature can be triggered. Additional free games can be won.
7. During the All Aboard feature, three bonus games are awarded. Only Train and Gold Coin appear on the reels. Gold Coins are held, and if one or more Train appears, the total prizes on all Gold Coins are awarded and the bonus game count resets to 3.

The rules also state that a player cannot influence the result of a game by stopping the reel spins, and that the game display does not indicate how close you were to winning. Any game in progress for more than 25 days will be cancelled and the corresponding bet refunded.

All Aboard Gameplay, Graphics & Sound

All Aboard uses a cartoony, colourful art style. The base game symbols are bright and readable, and the train theme becomes more obvious once the All Aboard feature begins. The feature screen replaces the standard reels with a grid of individual spinning positions, which is a visual change of pace from the base game.

Sound design is upbeat and celebratory. The feature is accompanied by a conductor-style call, and the repeated collection of Gold Coin prizes gives the bonus a distinctive rhythm. Players who prefer a quieter session may find the audio a little persistent, but it fits the train theme.

The multi-game cabinet version, as described by Konami, runs on the DIMENSION 75C cabinet. That is a land-based cabinet, so the visual experience there differs from any online or mobile version. If you are playing an online version, the graphics will depend on the operator's implementation and the device you use.

All Aboard Slot Features

The All Aboard series is built around two main features: a free games feature and the All Aboard Hold & Spin feature. The exact free games behaviour varies by version, so the details below focus on Dynamite Dash, where the rules are published.

Free Game Feature

Three Dynamite symbols trigger the free games feature. During the free game feature, the number of Miner symbols is increased. The All Aboard feature can be triggered during free games, and additional free games can be won. Different reels are used during the free game feature. Credits bet and lines played are the same as the game that triggered the feature.

All Aboard Feature

Any six or more Train symbols trigger the All Aboard feature. All remaining positions become individual spinning reels. Three bonus games are awarded. During the feature, only Train and Gold Coin can appear on the reels. At the start, all Train symbols change to Gold Coin, revealing either a Mega, Maxi, Major or Mini bonus, or a credit prize. At the end of each bonus game, each Train changes into Gold Coin revealing the same categories of prize.

Credit prizes are awarded as multipliers of the bet per line, with the exact values shown on the game's paytable. The chance of winning a Mega, Maxi, Major or Mini bonus, or a credit prize, changes with the bet per line.

The Grand Jackpot is awarded when all 15 positions are Gold Coin or Train at the end of a bonus game during the All Aboard feature. Credits bet are the same as the game that triggered the feature.

Bonus Features: Wilds, Multipliers, and Free Spins

All Aboard does not use a conventional multiplier wild system in the Dynamite Dash version. The Miner symbol acts as a wild, appearing on reels two, three, four and five only, and substituting for all paytable symbols except Dynamite and Train. There is no published multiplier attached to the wild in the rules we have.

Free spins are present as the free game feature, triggered by three Dynamite symbols. Additional free games can be won during the feature. The free games do not use a multiplier in the published rules.

Other versions in the series may have different free games features. For example, third-party descriptions mention features such as added wilds, doors reveal, giant middle symbol and multiplying wilds across different versions. Those descriptions are not from the official rules we have, so treat them as version-specific claims to verify on the game you are playing. The one consistent element across the series is the All Aboard Hold & Spin feature.

Other All Aboard Features

The multi-game edition on Konami's DIMENSION 75C cabinet includes a 1-level linked progressive with 4-level non-incrementing jackpots. Konami notes two options for linked progressive reset values. That is a cabinet-level feature, not a base-game mechanic, and it applies to the multi-game edition rather than every All Aboard version.

The Dynamite Dash rules also mention that the Grand Jackpot may be awarded randomly at the end of any bought game. That is separate from the All Aboard feature condition where all 15 positions are Gold Coin or Train. Both paths to the Grand Jackpot are described in the published rules.

There is no bonus buy option described in the Dynamite Dash rules. The features are triggered by symbol combinations during normal play.

Where to Play All Aboard

All Aboard is a Konami series, and Konami lists iGaming among its supported platforms. That means online versions may exist through licensed operators, but availability in Ireland depends on whether a particular operator carries the Konami iGaming catalogue and whether that operator is licensed to offer it here.

We cannot confirm which Irish-licensed operators currently offer All Aboard, and we will not list unverified availability. If you want to play, check the game catalogue of an operator you are considering and look for the specific version name. The multi-game cabinet version is a land-based product, so it will not be available online in the same form.

For general guidance on choosing a licensed operator in Ireland, see our Irish casino reviews and our Irish gambling laws guide. Those pages explain the regulatory context, but they do not confirm All Aboard availability at any specific site.
