Match-play bonus money is like a coupon you can use to place a wager.
Use your match-play bonus to play your favorite Java Casino game, wager on horseracing, play Keno/Lotto, or bet in the sportsbook.
Earning your match-play bonus is easy, the moment your wagering requirements have been met, you will be automatically notified.
The match-play bonus is added to your separate bonus account.
You can then use the match-play bonus to WAGER ONLY.
Any money you win by wagering your match-play bonus is instantly added to your account as real money.
