I'll save everybody's time and post the specific terms of the bonus offer you guys need to see;

"All welcome package bonuses are subject to a minimum 50x play-through requirement before being transferred to the player’s cash balance."

Basically, this means that you need to roll-over the bonus deposit funds 50 times in order for whatever is left to hit your account.

With an unknown house edge, that almost certainly means you'll lose both your initial deposit and your bonus deposit within a few tries, even playing a low house edge game.
