How We Review and Test a 300% Casino Bonus
We test each site in a 5-step process. Vlad George Nita and his team created this list of the best casinos offering a 300% bonus for the UK. Here’s how we review it before recommending to you:
- 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.
Be Aware of Your 300% Bonus Terms
You must understand the limitations of this type of promotion before you claim a 300 % first deposit bonus:
| Significant 300% bonus terms | Explanation |
|---|---|
| Minimum deposit | It means the payment required to activate the 300% bonus. £10 is a low deposit value. Anything more than £20 is high. |
| Bonus percentage | It refers to how much % of your deposit you get as bonus funds. A 300% bonus is considered rare. |
| Wagering requirements | It refers to how many times you need to wager the bonus to cash out. The average in UK is 40 times. |
| Win limit | It translates into how much you keep after you wager your bonus. It can refer to winnings from free spins, bonuses or real money. |
| Eligible games | It refers to the titles you are expressly informed you can play in the bonus T&Cs. |
| Excluded games | Some games are forbidden to play with bonuses. Playing them may result in void winnings and canceling bonuses. |
| Maximum bet limit | It states how much you can bet at once with your bonus. It is expressed either as a percentage or value, or both. The lowest of the two usually applies. |
| Maximum bets for e-wallets | PayPal, Skrill and Neteller depositors may have a reduced maximum bet limit. For example, a VISA depositor may be able to bet up to £5, while the limit would be £2.5 if you claimed with Skrill. |
| High wagering contribution on slots | For most 300% deposit bonuses, bets in slots count entirely for the wagering progress; 100% of your stake in slots contributes to the playthrough. |
| 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. |
| Doubling excluded | There may be restrictions on using the Gamble feature in slots, doubling down in blackjack and any other form of doubling bets. |
