300% Deposit Bonus UK Explained

A match deposit bonus is a form of bonus where the casino will match your deposit by a certain percentage. There’s usually a minimum amount that you need to deposit to claim the offer. In the case of a 300% match deposit bonus, you receive a 300 per cent ‘markup’ based on your initial deposit amount which is credited as bonus funds. This can be redeemed by playing casino games as stated in the terms and conditions. As an example, let’s assume you made a first deposit of £20, which is in line with the min deposit requirement of the 300% match deposit bonus offer. In that case, you will be offered a £60 bonus.

Tips and Tricks To Get The Most Out Of Your Deposit Bonus at an Online Casino

Getting the most value out of your deposit bonus is heavily dependent on how you go about using it. Here are a few tips that may come in handy:

• Only claim a 300 deposit offer with favorable terms – 30 days validity and not more than 40x wagering requirement;
• Play slots as they contribute 100% to the wagering contribution (see if you can take advantage of free spins);
• Choose high RTP slots from 92% when redeeming a 300% deposit game bonus, as they give you a higher potential of winning;
• Avoid live casino games if the casino doesn’t directly states the 100% wagering, as they usually don’t qualify when trying to wager the bonus;
• While bingo bonuses can be tempting, their inconsistent RTP could result in a low chance of bingo bonus winning ;
• Avoid abusive bonus activity across sites, such as opening multiple accounts with multiple profiles;
• Check the bonus activity across sites operated in the UK – player reviews will give you a good indication of their real money value.

Best Games To Play With 300% Deposit Offers

300% deposit bonuses give you more bonus funds to play top slots like Mega Moolah and Gonzo’s Quest. Slot sites tend to offer free spins instead of huge deposit matches.

Live dealer games like roulette and blackjack usually have lower wagering contributions. But with a 300% match, you still get substantial bonus funds to play live games for real profits after meeting wagering. There are still some top online live casinos with deposit matches, so always check our listings for those.

5 Bonus Terms You Need To Consider Before you Claim a 300% First Deposit Welcome Bonus

Before you use casino deposit bonuses, there are terms and conditions that you should pay close attention to.

Wagering contribution

Not all casino games have the same wagering contribution. By standard, slots bonus funds count towards 100% of the wagering contribution, while other games, like table games, contribute around 15%. It is important to look through the terms of the bonus to see what each game type contributes to the wagering contribution.

Eligible games for the Casino Bonus

It is highly recommended you go for 300 deposit bonuses that allow you to use them on a wider variety of casino games. For example, if you’re skilled in live blackjack, baccarat, or craps, the potential RTP can be close to 100%.

Maximum bonus win potential of the First Deposit Bonus

This is another factor that shouldn’t be ignored, as it is the games bonus win cap. While a welcome offer with a 300% deposit bonus can be attractive, some might let you cashout smaller amounts than you’d expect.

Wagering Requirement of the 300% match offers

This is not to be confused with wagering contribution. The wagering requirement indicates the number of times you are to wager a bonus before you can cash it out. The standard wagering requirement is about 40x. Anything above that should be avoided.

Minimum Deposit Amount

The minimum deposit amount for 300% deposit match bonuses varies from one casino to another. For many, the min deposit £20 is the standard, while others go as low as min deposit £10.

Best Alternatives For 300% Deposit Bonus UK

The 100% deposit bonus is a good starter for new casino UK players because the minimum deposit is usually lower than £15. The 200% deposit bonus offers were created for medium budgets and usually have deposit spins alongside the matching deposit. The 300% and 400% offers have higher minimum deposits and are more suitable for VIP casinos and players. These high stake casinos also include roulette and blackjack tables with different betting limits.
