How We Review and Test a 300% Casino Bonus
- Finding 300% deposit bonus percentages: Our affiliate experts scan the market for legit UK casino operators that offer 300% bonus codes for United Kingdom players. They only select fair UK casinos, which confirm the bonus percentage and give the green light to the testing process.
- Studying wagering rules: While we’re still preparing to play, the second step of our testing process is checking the general Bonus Policy and the offers’ Terms and Conditions. Mapping out the individual bonus terms and wagering rules allows us to compare with the UK average and recommend the best 300% bonus offers.
- Real money deposit: Our reviewers create UK player accounts for every listed offer and deposit the minimum amount (usually 5-20 pounds) to activate the 300% match percentage. This is how we obtain all the payment-related data and test the bonuses hands-on.
- Playing eligible games: Once the bonus is activated, we start wagering in eligible games while keeping an eye on the types of bets accepted. This process takes around 10 hours per casino.
- Cashing out; The final step of our testing procedure for 300% deposit bonuses is attempting to cash out the resulting winnings. We prioritize bonuses which simplify the cashout process.

|Minimum deposit||It means the payment required to activate the 300% bonus. £10 is a low deposit value. Anything more than £20 is high.|

|Low wagering contribution on live games||For most 300% bonuses, bets in live dealer games contribute around 10% of their value.|
|Restriction of payment methods||Some payment methods may be excluded from claiming the 300% casino bonus. Trying to use them may forfeit your bonus.|
