Lucky Nugget gives you the money to play with and you get to keep the winnings. Where's the catch?
The catch, it is fair to say, is in your ticking clock: you have only 1 hour (60 minutes) to use this offer and do your best. If it's 50GBP that you make over the original 1,000 you get from the casino, then it's 50 GBP that you keep. If it's more, then all the better!
If you're a new player at Lucky Nugget with a real account, you can pick one of several promotions that welcome you to the casino. One of them is the Free Spins offer. It's a simple matter of downloading the software, installing the casino, and without a deposit even - signing up for a Real Money account and confirming your e-mail address.
You will then be credited with 1,000GBP free credits. An hour later, any sum that you make over and above the original 1,000 will be yours to keep.
