To answer your questions in reverse, yes, there are several different games on the Color Poker handheld device, including draw poker, deuces wild, bonus poker, double bonus poker, double-double bonus poker, jokers wild, and double jokers wild.
Since we first began stocking it for the holidays three years ago, Color Poker has consistently sold out. It's the only handheld game that we now carry all-year long. Or, rather, we would if we could. The bad news is that the company who supplies us has completely sold out (they kindly dug around in the darkest recesses of their warehouse to find the last half-dozen games) and has no idea when they might be back in stock. The games are imported from China and the combination of a warehouse fire and various natural catastrophes has put a serious crimp in the supply chain, meaning they have no clue when these games will become available again, if at all.
We're sorry we can't be more positive and we do keep checking back to see if there's any update (we called yesterday and there wasn't), so if Color Poker becomes available once more, you'll be the first to know.
