The popularity of poker is at an all-time high, but one golden rule remains: If you can't spot the sucker in the first five minutes, you probably are the sucker. So before you lay your cash down, try honing your skills with these digital alternatives. The PC is the poker king, but mobile and TV games are joining the table, and new games like Texas Hold 'Em have superseded classics such as stud and draw poker. So practice away—and work on your poker face.
