What is a 300% Deposit Bonus?
When players deposit with an online casino, they can receive extra funds from the casino as part of a deposit match deal.
Simply put, a 300% casino deposit bonus is when a casino site matches your first deposit up to a certain amount. In this case, online casinos with a 300% deposit offer will triple your bankroll.
Let’s look at a concrete example to understand the concept better. If a player deposits £100, casinos will give another £300 on top, making the total playable balance of £400.
However, you need to understand the bonus terms to benefit from a 300% bonus match.
Advantages and Disadvantages of 300 Casino Bonus
If you have experience playing video slots, you probably already know that it only takes one lucky spin to score a massive win. Keeping that in mind, the most obvious advantage of the 300 deposit bonus UK has to be the fact that you have more chances at scoring that spin. Before you head out to one of the casinos on our list to collect your bonus, let’s check out some pros and cons.
Advantages
- Having a large bonus balance lets you play slot games with high volatility.
- You can place larger wagers on slot spins. However, you must check the maximum allowed bet first.
- With a tripled bonus balance, you can test your luck on new titles that you might not have considered otherwise.
Disadvantages
- The only real drawback is that you need to wager the entire bonus balance. Depending on the online casino, the wagering requirements could be set at around x20-x60. If you plan on making a large deposit, you need to allocate enough time and patience to play through the bonus.
Common Terms and Conditions
Every casino will have its set of bonus terms and conditions that you need to read before making a deposit. In most situations, the bonus balance will be automatically awarded to your account when you deposit.
Bonus Wagering Requirements
Wagering requirements refer to the amount of money you need to wager before the balance becomes available for a withdrawal. For example, if you deposit £10 and receive a 300% deposit bonus UK, you will be playing with £40. If the wagering requirement is at x30 multiplier on a £40 bonus amount, then it means you would need to wager at least £1,200. After you have finished wagering, the whole balance will be turned to cash, and you can request a withdrawal or continue playing.
Time Limits
Casinos will usually limit how long you have until you can clear the wager. In most cases, you can expect a bonus to expire after a week, and if you have not finished the playthrough, the whole balance will be voided.
Another type of limitation might be to impose a cooldown on how long you can take before you claim the promotion. This scenario is most common for newly registered players with five or seven days to deposit and qualify for the bonus match of 300 percent.
Minimum Qualifying Deposit
There will be a minimum deposit to qualify for a 300% casino bonus most of the time. Each casino updates its promotions, and the minimum required deposit can change from one to another.
Wagering Contribution Percentages
In most cases, you can achieve 100% wagering contribution from video slots, keno, or scratch cards because the house’s edge is higher on these games. A game like Blackjack, where the house edge against an inexperienced player is only 2%, will have a much lower contribution to the playthrough requirements.
You can find wagering contribution percentages in the bonus terms and conditions. You can expect Baccarat, Roulette, Blackjack, Craps, and video poker to count anywhere between 10% and 20% towards wagering. Meaning that if you place bets for £10, you will wager £1-2. And slot games would count 100% towards wagering in most cases.
Excluded and Eligible Games
We mentioned above that games like Blackjack or Roulette can have lower wagering contribution percentages, but in some cases, they can be excluded from playing with the bonus altogether. Online slots with very high RTP percentages, above 97%, might also not count towards wagering requirements.
There are cases, albeit rare, where you can only wager the bonus on a specific slot games or titles from the same game provider. You can still play any other video slot on the casino website, but they would not count towards playthrough contribution.
Maximum Allowed Bet
The max bet rule is widespread with most online casinos. Typically the most you can wager on a single spin is £5-10, and if you go above, there are two possible scenarios.
The more lenient version will simply have bets above the threshold not count towards the playthrough requirements. However, going above might result in the entire bonus balance being voided.
