OP should verify whether or not the "casino play" is of the 'keep until you lose' variety. Typically, winnings from tournaments given in chips are of that type, but some promos are single play only (i.e., bet on BJ, casino takes your original bet whether you win, push, or lose).

Ya, the good ol' days of Vegas. Now it's a joke. I remember one recent Bellagio 'million dollar BJ tournament' was actually something like 100k in promo chips plus four 50k sports bets and a 200k Super Bowl bet, of which all five had to be won to get the last 500k.
