Grand Mondial Online Casino has introduced an exciting new 400% Welcome Offer that consists of 2 Purchase Match offers, a fantastic insurance bonus that lets you win even when you don’t, and a monthly interest rate bonus on your cash balance.

Make a first purchase of 20 and play with 100, and on your 2nd deposit receive a 100% Match up to 100, as well as a 25% Insurance Bonus that pays out in case you don’t end up winning anything, which means you simply cannot lose!

And for those existing players who might feel just a bit left out with such an amazing offer, the good news is that the Interest Bonus is valid for both new and current players! So what does this Interest Bonus entail?

Simply put, players earn a daily interest rate of up to 15% on their cash balance. The interest is calculated at a daily rate on the player’s cash balance, and it then accumulates into a generous lump sum that is paid into the player’s bonus account on a monthly basis. In other words, this amounts to a generous pay day for loyal players.

And this is no inflexible interest rate either. The more you play and build up your credit balance, the more you get in return – up to 15%! That’s more than most banks offer!
