Tips & Examples

  • • Normal Bet: Use for standard matched betting promotions
  • • Free Bet (SNR): Stake Not Returned - use for most free bet offers
  • • Free Bet (SR): Stake Returned - less common but higher value
  • • Example: £10 back at 2.50 odds, lay at 2.52 = £9.80 lay stake
  • • Lower commission = higher profits (Betdaq 2%, Smarkets 2%)
