The SL Gambling Policy says,

It is a violation of this policy to wager in games in the Second Life® environment operated on Linden Lab servers if such games:

1. Rely on chance or random number generation to determine a winner,

   OR

2. Rely on the outcome of real-life organized sporting events,

AND provide a payout in

1. Linden Dollars (L$)

   OR

2. Any real-world currency or thing of value.

As long as your game doesn't run afoul of those limits, you're probably OK. Please note, however, that Lindens never come to this resident-to-resident Answers site and that nobody here can give you a guaranteed legal opinion.
