300 Deposit Bonus UK – £300 & 300%

It’s possible to get a 300 deposit bonus at a casino. This can actually mean one of two things. Either you’ll get up to £300 in extra bonus money or you’ll get 300% of the value of your deposit. Both require you to deposit your own money to activate. So it’s important to understand how both work. Below we’ll explain the £300 deposit bonus and the 300% deposit bonus in full. But first, here’s a list of casinos where you can get these offers.

The best casino offering a £300 deposit bonus for UK players is Playzee. This means you can get up to £300 in extra bonus money to play slots and games. However, it depends on how much you deposit yourself.
For example, let’s say a casino offers 100% up to £300. The amount you deposit will also be given to you as bonus money, up to the maximum of £300:
- Deposit £100 – Get an extra £100
- Deposit £300 – Get an extra £300
- Deposit £400 – Get an extra £300 (as £300 is the maximum you can get)
Of course, unlocking the full offer requires a large deposit. This will give you the most amount of extra money to test out the slots and games.
However, you can still deposit lower amounts too. You just won’t receive the full amount.
The wagering requirements and terms and conditions should be read before you start playing, so you understand the obligations in full.

The best casino offering a 300% deposit bonus for UK players is Unibet. This means they will triple whatever you deposit up to the maximum amount.
For example, let’s say a casino offers a 300% deposit bonus up to £100. You will get extra bonus money three times what you deposit, up until the cut-off point:
- Deposit £20 – Get an extra £60
- Deposit £30 – Get an extra £90
- Deposit £40 – Get an extra £100 (as £100 is the maximum you can get)
Often, 300% bonuses are better suited to players wanting to put down smaller sums of money. However, make sure to check the terms and conditions before playing for the full breakdown.
300 slots bonus
Whether you choose the £300 or 300%, you’ll be able to use the money as a 300 slots bonus.
More often than not, you’ll be able to play all kinds of slots and games, as they aren’t typically restricted to a single provider or game. But players should always remember that different slots contribute different amounts to the wagering requirements.
For instance, a normal video slot may contribute 100% of the bet to satisfying the wagering requirements, whilst blackjack or roulette may only contribute 50% of the bet. Ultimately this means if you’re betting £1, the whole stake will contribute to the wagering requirements for the slot, but only £0.50 would contribute for blackjack or roulette. Each casino will publish the contributions of each game on their site.
