Sites offering a 150% bonus. To calculate a 150% bonus multiply your first deposit by 1.5. E.g If you deposit £10 you would get £15 free which is £25 in total to play.
Although a 150% bonus might not seem that amazing compared to the other bigger bonuses out there, you will find that the wagering requirements are a little less restrictive to make up for it.
Some sites will not apply the bonus if your deposit is less than £10. Similarly sometimes the bonus has a maximum amount you can deposit to be eligible. It's always worth checking the terms and conditions before making a deposit to find out if you can withdraw any winnings from your bonus money.
