A slot bonus offered by a casino will usually give you a small addition to your deposit in the form of free spins or a 100% match bonus.

The casinos listed on this page will quadruple your initial deposit giving your bankroll a huge boost to play slots for.

TERMS AND CONDITIONS OF A 400% CASINO DEPOSIT BONUS

Bonus terms and conditions should always be checked as many bonuses come with strict requirements.

Some bonuses can only be used on certain slots whilst others have wagering requirements. 

WHY CHOOSE A 400% BONUS?

  • You will quadruple your original deposit
  • Allows you to play a greater number of slot games
  • Gives you a large bankroll without risking much of your own money

OTHER SIMILAR BONUSES
