Apparently, they are offering a $50 match play if you book online. And you also have the LVA $50 matchplay coupon. Now, each coupon has a mathematical value of slightly less than $25. Here's how to put that value in your pocket no matter what:
Go to the craps table. Bet $50 with the coupon on the Pass line. At the same time, bet $75 on the Don't Pass line. To cover the possibility of a comeout 12, bet $2 on the 12 (prop bet).
Now, no matter what happens, you will score a $23 profit, unless there's a comeout 12, in which case, you will only win $10 ($60-50). In all cases, when the Pass Line bet is resolved, pick up your bets and walk away. DO NOT keep playing!!
Space out the two matchplay plays rather than doing both at once, as some pit worms voice objections when you do this, even though you are absolutely not violating any rules. If you ARE told that, just shrug and come back later, when said worm has slithered away.
