  • 1st Deposit Bonus: 121% bonus (up to £300)
  • Minimum Deposit: £10
  • Promo Code: N/A
  • Wagering requirement: 35x

The best slots sites offer new customers a welcome package that is good value-for-money with realistic and fair wagering requirements.

21 Casino is one such site as it lets you claim a 121% bonus of up to £300 when you make your first deposit of at least £10. You must play through your bonus funds 35 times to convert them into cash and you have 30 days in which to achieve this.

You can also place bets of up to £5 with your bonus funds which seems very reasonable. However, if you try to withdraw any cash funds before you’ve met the bonus wagering requirements, you will lose your bonus.
