Box Bonanzas at Rainbow Riches Casino

At Rainbow Riches Casino, we’re always seeking new and exciting ways to create fun for our valued players, which is why we offer Box Bonanza rewards for the chance to win marvellous cash prizes!

How do I play a Box Bonanza game?

When you enter the Box Bonanza game, three boxes featuring random prizes will appear. Your aim is to find the box with the hidden cash prize! You can only pick one box in each game, so choose carefully…

Am I guaranteed a win?

Box Bonanzas can be awarded at random or by taking part in various promotions. To see if you have won a Box Bonanza, log into your account and check ‘Your Offers’.

Each box contains a completely random value, which could be zero. There is no maximum prize (unless otherwise stated) but you will only win a cash prize if you find the right box!

What will happen if I win?

If you find the cash prize, then your winnings will be available to play with immediately! To check your pot of gold, log into your account and head over to ‘Reward History’. If we find ourselves experiencing an unexpected delay, please wait 72 hours for your prize to appear.

Where can I use my prize?

Your prize can be used on any of our splendid slot machines, so step on in and explore the wonderful world of Rainbow Riches Casino! Whether you’re looking for slot classics, such as Cleopatra, or something new to discover, we’ve got plenty to choose from. Why not try some of our favourite slot games here?

Can a Box Bonanza expire?

We don’t like to hurry you along, but we like to make sure our promotions are fresh for you to enjoy, so Box Bonanza games will expire after a certain amount of time. Take a peek at the T&Cs at the bottom of the Box Bonanza pop-up to see how long you have left to make your pick!
