Relax Gaming is both a studio and a distribution platform, which is why its own releases tend to be technically ambitious — they are built to show what the platform can carry.
The Money Train series is the studio's flagship and one of the most imitated designs in slots. Its bonus round is a persistent grid where symbols hold values, respin, and act on each other: collectors gather every value on screen, payers add to them, and the round only ends when a set number of spins passes without a new symbol.
Hellcatraz and the Tumble games take a different route, using cascading grids where clearing symbols opens more of the board.
Money Train's bonus is the part worth seeing, and in real play it is rare. Free play lets you reach it. All Relax Gaming titles here load directly in the browser on desktop and mobile.
