Initiate the Wild train and collect wild symbols and chest symbols to grow the train and gain respins. See it become a string of wilds and grant lots of winning lines with every respin! Collect 9 in a single bet round (including respins) and get 5 free games! Add 1 free spin with every wild or chest symbol that appears, and behold how the Wild Train keeps growing. But that’s not all! Collect up to 21 Wild symbols within the same bet round, and hit the 5,000x jackpot! Or collect 21 triple coin symbols (scatter with values) to enjoy a 20x multiplier on the total scatter value! While collecting wilds, users may randomly enter a Pick Bonus that grants 1 of 4 jackpots: Mini, Minor, Major and Grand.
