Onlyplay launches new high-volatility slot 'Halloween Train: Hold & Win'

iGaming content provider Onlyplay has launched Halloween Train: Hold & Win, a high-volatility, Halloween-inspired video slot set in a train ride.

The game features pumpkins, ghosts, witches, and lanterns on a 5x3 reel setup, offering a 97.00% RTP and a 13.37% hit rate.

The key feature is the Hold & Win Bonus Game, triggered by collecting five Bonus Symbols. Unlike traditional respin rounds, this feature continues through multiple stages: when the reels fill, the field clears for a new round with fresh bonus symbols and higher potential rewards. A Sticky Collect Symbol remains in place, gathering winnings from each round and adding them to the total.

Players can also chase four progressive jackpots—Mini, Minor, Major, and Grand—linked directly to the bonus symbols that appear. Additional features include Trains Pays, which rewards players the moment a “Train” symbol appears on the central reel by paying out all visible coin values immediately. Meanwhile, the Lucky Train feature injects unpredictability by randomly dropping new coins onto the reels and starting the Coin Game anew.

"Halloween Train: Hold & Win combines a classic spooky theme with innovative mechanics, giving players a chance to chase endless rounds, sticky rewards, and truly monstrous wins," the company said. "This Halloween, step aboard the haunted rails and experience a slot ride unlike any other."
