. The Welcome Bonus is based on a New Player’s first and second approved deposit at the casino provided that he meets the conditions for the bonuses. 2.

Players from Greece and Lebanon X 80. 5. Bets placed on all games other than slot machines will be deemed a violation of the terms and conditions, your bonus and winnings will be voided.

A 400% Deposit Bonus will give you x4 your deposit amount.  So you know how much you’re playing with, here are some examples below.

400% Deposit Bonus breakdowns:

  • £10 Deposit will get you a £40 Bonus, so you have £50 in total to play with.
  • £20 Deposit will get you a £80 Bonus, so you have £100 in total to play with.
  • £25 Deposit will get you a £100 Bonus, so you have £125 in total to play with.

You will usually see 400% Deposit Bonuses promotion worded as:

  • Deposit £10, get a £40 Bonus and play with £50.
  • Deposit £20, get a £80 and play with £100.
  • Deposit £25, get a £100 and play with £125.

The above amounts are the most popular player deposits. Any other amounts are pretty easy to work out from the above. I always think from a £25 deposit it’s hard to work out the bonus and play with amounts. So I hope I’ve just made your life a touch easier.

With a 400% Deposit Bonus you will get a huge amount of extra playing time, which in my book is always great.
