With each release, the games have gotten bigger and bigger, and true to form, Money Train 4 is the biggest one of them all. Big, a little scary, hugely entertaining, brutal, yet potentially hugely rewarding, the Money Train range of slots has been a flagship number at Relax Gaming since the first one dropped back in 2019. If there are any slots that need little introduction, it is those in the Money Train range. Get your tickets, folks, because a little ol' caboose called Money Train 4 is about to chug its way on into town.
