Why this machine isn't on our advantage play list
Konami's hold-and-win feature triggered by 6+ train symbols on the reels. Train symbols lock with credit values; new trains landing on respins reset the spin counter and add to the total.
Variants include Dynamite Dash, Piggy Pennies, Go West, and Masked Warrior.
The All Aboard Multi-Game cabinet hosts multiple themes under a 1-level linked progressive with 4 fixed jackpots.
The train feature is event-triggered (six trains on a single spin), not state-driven. There's no on-screen accumulation that carries over between players.
The progressives are 1-level linked plus fixed jackpots, with no must-hit-by behavior advertised by Konami.
Popular and entertaining, but no exploitable edge.
For Konami banking with persistent state: Money Galaxy
For must-hit-by progressives: Buffalo Ascension
