1. Money Train 2

Money Train 2

This is one exhilarating train ride you won't want to miss at any cost!

Back with bigger win potential and base features that keep more than the reels rolling. With a 50,000x win up for grabs, Money Train 2 could offer the adventure of a lifetime.

3 or more scatters kick-start the adventure in the Money Cart Bonus Round, where players get the help of some of the best crooks in the business: the Collector, the Payer, and the Sniper.

Persistent characters activate with each spin while the un-persistent run out of steam after a single activation – until the Necromancer turns up to bring them back to life. 3 spins get players started in the Bonus Round, with the chance of winning more with every symbol that lands. Scatters with a value are added to their winnings, while the Payer adds her own value to the pot.

The Sniper doubles the value of up to 8 symbols, while the Collector sums up all the values and chips on his own. When a reel fills with symbols, another column is added, bringing, even more, win potential. It's no wonder you might be racing to the Buy feature, they can cut right to the chase and go straight to the Bonus Round. Are they ready for action?
