You can work for your money, or you can just win it from the local gamblers in the saloon. Out-bluff your competition in a Texas Hold 'Em tournament. Play your cards right, and you'll come up all Aces.
All you need to do it take chips from the other people on the table, there are 500 chips in all and four other people it's easy once you get the hang of it. The first three poker tournaments take place in Dodge's Alhambra and the other three take place in Hoodoo's house (or is that the majors house) in Empire. Do the missions as early as you can so you can't lose money but you can win it big time, $10 to $60 now that's a lot.
