Walker Poker is a fairly new contender to a lot of people, just joining the Merge Gaming Network when they were created in February 2007, but Walker Poker has been around for about 3 years altogether. With their player base growing due to being on the Merge Gaming Network, they're sure to get a lot more attention soon. They also allow U.S. players, which is still an incredibly big deal.
However, WalkerPokerInstaller.exe is on the large side, coming in at 11.1 MB. This is definitely a little bigger than those on less than cable would prefer, but if you're using cable and up, you'll be fine. Once you get into the Walker Poker download and begin to install it, you'll notice that only English is utilized in the poker room download. This is a bit of a beat, but still manageable. Once you get the poker room download up and running, you'll notice that despite its download size, it's extremely easy to breeze through the setup. It's also very, very simple to boot.
If you're looking to head on over to Walker Poker, get the WalkerPokerInstaller.exe and hit the tables!
