300% Deposit Bonus – What It Is and How It Works
A 300% deposit bonus is a casino promotion that gives players three times their deposit amount as bonus funds. For example, if you deposit £100, the casino adds £300 in bonus money, giving you a total of £400 to play with.
While 100% and 200% deposit bonuses are common, finding a 300% first deposit bonus is rare. Casinos that offer these high match bonuses usually impose strict conditions, such as higher wagering requirements and game restrictions. However, these bonuses can significantly extend playtime and increase the chances of winning.
Why Are 300% Deposit Bonuses Rare?
- Casinos take on more risk, which is why 300% deposit bonuses often come with strict playthrough conditions.
- These promotions are typically available for new players as part of a welcome package or a special offer.
- Higher bonus amounts mean casinos enforce higher wagering requirements (usually 35x-50x) and game restrictions.
- Some casinos offer a high roller 300% casino bonus, designed for players who deposit larger amounts.
Key Benefits of a 300% Deposit Bonus
- A significantly larger bankroll – deposit £100 and play with £400.
- More opportunities to place bets and explore different games.
- Some casinos include free spins along with the 300% first deposit bonus.
Important Considerations Before Claiming
Before choosing a 300% deposit bonus, always review the terms and conditions carefully:
- Casino bonus wagering requirements – A 40x-50x playthrough means a £300 bonus requires betting £12,000-£15,000 before withdrawal.
- Eligible games – Many offers count only slots at 100% towards wagering, while table games may contribute just 10%-20%.
- Time limits – Some casino bonuses expire within 7-14 days.
- Payment method restrictions – Certain casinos exclude deposits made via Skrill, Neteller, or PayPal.
A 300% deposit bonus can be a great way to increase your bankroll, but always compare offers to find the best deal.

How to Claim a 300% Deposit Bonus
Claiming a 300% deposit bonus is simple, but it’s essential to follow the correct steps to ensure eligibility. Different casinos may have specific rules regarding deposits, bonus codes and casino bonus wagering requirements.
Step 1: Choose a Reputable Casino with a 300% Deposit Bonus
Not all casinos offer a 300% deposit bonus, so it’s important to compare the best 300% deposit bonus casinos. Check the wagering requirements, eligible games, and expiration dates before signing up.
Step 2: Register and Verify Your Account
Create an account by providing basic details. Some casinos require identity verification before allowing withdrawals, so be prepared to submit documents if needed.
Step 3: Make a Qualifying Deposit
Ensure your deposit meets the minimum required amount for the 300% sign-up bonus. Some casinos exclude Skrill, Neteller or PayPal deposits from bonus eligibility, so verify accepted payment methods.
Step 4: Enter a Bonus Code (If Required)
Certain casinos require a bonus code when depositing to activate the offer. If claiming a high roller 300% casino bonus, VIP players may have a separate code. Always check bonuses terms.
Step 5: Play and Meet Wagering Requirements
To withdraw winnings, you must fulfill the casino bonus wagering requirements. Slots usually contribute 100%, while table and live dealer games may count only 10%-20%. Many casinos also enforce a maximum bet limit while using bonus funds.
Step 6: Withdraw Your Winnings
Once the wagering requirements are met, go to the cashier section and request a withdrawal. Some casinos apply maximum cashout limits on 300% deposit bonus winnings, so always review the terms before cashing out.
By following these steps, you can successfully claim and use your 300% deposit bonus without missing any key conditions.
Types of 300% Casino Bonuses
Casinos offer different versions of a 300% deposit bonus, catering to both new and existing players. Some are designed for first-time deposits, while others reward loyal players with reload bonuses.
300% Welcome Bonus Package
This offer is split across multiple deposits rather than given all at once. A typical structure might include:
- 150% on the first deposit
- 100% on the second deposit
- 50% on the third deposit
Best for: Players who prefer a longer bonus experience.
Example: A £100 deposit grants £150 in bonus funds, totaling £250.
300% First Deposit Bonus
This is the most direct 300% first deposit bonus, where the player instantly receives three times their deposit.
Best for: Those who want a large bankroll boost immediately.
Example: A £100 deposit gives a £300 bonus, for a total of £400.
Watch out for: High casino bonus wagering requirements (typically 35x-50x).
300% Reload Bonus
A high roller 300% casino bonus or reload bonus is aimed at returning players who deposit again after their first offer.
Best for: Regular depositors looking for extra value.
Example: A £200 deposit results in a £600 bonus, totaling £800.
Limitations: Often restricted to specific days or VIP members.
300% Bonus + Free Spins
Some casino bonuses combine a 300% deposit bonus with free spins on selected slots.
Best for: Slot players who want extra spins along with their bonus.
Example: A £50 deposit grants a £150 bonus plus 100 free spins.
Things to check: Wagering requirements apply to both the bonus funds and free spin winnings.
Each type of 300% deposit bonus serves a different purpose. Whether it’s a first deposit offer, a reload deal, or a high roller 300% casino bonus, understanding the differences helps in choosing the best promotion.
Wagering Requirements Explained (With Examples)
A 300% deposit bonus can significantly boost your bankroll, but before you can withdraw winnings, you must meet the casino’s casino bonus wagering requirements. These requirements determine how many times you need to wager the bonus (or sometimes the bonus + deposit) before cashing out.
What Are Wagering Requirements?
Wagering requirements represent the number of times a bonus must be played through before a withdrawal is allowed. They are usually written as a multiplier (e.g., 40x or 50x bonus).
For example, if you claim a 300% deposit bonus and receive £300 in bonus funds, a 40x wagering requirement means you must bet £300 x 40 = £12,000 before cashing out.
Example Calculation
Let’s break it down with a real example:
- Deposit: £100
- Bonus Received: £300 (300% first-time deposit offer)
- Total Playable Balance: £400
- Wagering Requirement: 40x on the bonus amount
- Total Bets Required: £300 x 40 = £12,000
If the wagering requirement applies to both the deposit + bonus, the calculation changes:
- Total Deposit + Bonus: £400
- Wagering Requirement: 40x on total amount
- Total Bets Required: £400 x 40 = £16,000
Low vs. High Wagering Requirements
The best casinos offer fair wagering conditions. Here’s what to look for:
- Low Wagering (≤35x bonus): Easier to clear; better value for players.
- Medium Wagering (35x-45x bonus): Standard for most UK online casinos.
- High Wagering (50x+ bonus): More difficult to complete; often found in high roller 300% casino bonus offers.
Game Contribution to Wagering
Different games contribute differently toward meeting casino bonus wagering requirements:
- Slots: Usually count 100% toward wagering.
- Table Games (Blackjack, Roulette, Poker): Typically contribute 10%-20%.
- Live Dealer Games: Often contribute 0%-10% (some casinos exclude them entirely).
For example, if a casino states that blackjack contributes 10%, then wagering £1,000 on blackjack would only count as £100 toward the requirement.
Tips for Clearing Wagering Faster
- Play high-RTP slots that contribute 100% to the requirement.
- Avoid games with low contribution rates like table games.
- Stick to maximum bet limits—most casinos impose a £5 max bet while using bonus funds.
- Look for top-rated casinos with 300% deposit bonuses with wagering requirements of 40x or lower for better value.
Understanding wagering requirements is key to maximizing the value of a 300% deposit bonus. Choosing a casino with fair terms and playing eligible games wisely will improve your chances of turning bonus money into real cash.

A 300% deposit bonus is one of the most generous casino promotions, but how does it compare to other common bonus types? The key differences lie in bonus size, wagering requirements, and suitability for different types of players. Below is a comparison of the most popular casino bonuses.
| Bonus Type | Bonus % | Typical Wagering | Best For |
