gambling

We play pool or billiards sometimes for fun and play “loser pays”, meaning whoever loses has to pay the fee for the table rental. Is this halal (lawful)?

Dear respected sheikhs, as-salamu `alaykum.Most entertaining games in jails are playing cards, dominoes, chess, and others. So, how far is it permissible for a Muslim to participate in these games? Jazakum Allah khayran.
