On reading the terms and conditions of a weekend leaderboard offer at Bwin, came across their definition of a cash prize...

Cash Prize Terms and Conditions

  • Cash Prizes are awarded as Non-Deposit Bonus with 10x wagering restrictions and can be immediately withdrawn by the player once the wagering restrictions are met.
  • The bonus will be available to claim in the casino bonus section of the Eligible Player’s account for 24 hours. Failure to claim the Non-Deposit Bonus will result in the bonus expiring.


Why call it cash?

Just call it what it is...a bonus (with wager/withdrawal restrictions)

It is amusing that they say that it can be immediately withdrawn once wagering restrictions are met.
How generous
