- You need to deposit £10 and spend £5 on three separate days to qualify for the offer. You may have already qualified for the first day from completing the welcome offer but make sure to check. If so then come back the next day

- Repeat this again on following days until you have done it on three separate days. You will then get a pop-up advising you that you have qualified for the Box Bonanza game. The game will be available to play one week after you signed up - so set a reminder to come back a week after you signed up
- When you come back after a week, you should be able to open the Box Bonanza game and get a random cash prize
- On your promotions page, you may also see an offer to get a free Box Bonanza when you opt into all marketing channels. This should be worth around £2
