One of the reasons PokerStars draws a lot of players is that they have great software.
Players are allowed to upload any non-offensive avatar of their choice to represent them at the table. The basic color scheme of the table is variations of tans which are neutral to the eye. Players can also download various table skins to allow more freedom of personalizing the site to fit their style. Tables can be re-sized to allow multi-tabling on any resolution screen. Players have access to one of the best note-taking functions in the industry, as well as a very good, intuitive statistics screen. Players have leeway in turning player avatars and chat on or off, and PokerStars offers a four-color deck option with a multitude of cardbacks to help players customize their experience.
The main menu is both easy to understand and easy to navigate. Ring game table menus allow their players to take advantage of hands/hour, players seeing the flop percentages as well as average pot sizes, in order to facilitate table selection.
Menus for ring games, tournaments and SnGs are all easily navigated and have numerous filters to allow the player to find the right tournament, at the right time and for the right price, quickly and easily.
