When at the game room, the HUD (heads-up display) is displayed at the bottom of the screen. From Wikipedia, "In video gaming, the HUD or status bar is the method by which information is visually relayed to the player as part of a game's user interface."
Displayed on the HUD are the name of the player, the player's wins, how many game turns are remaining for that player, and the score for that player. total win, turn or score feature may not be seen on the HUD when playing a game because that game might not support a feature.
The turns text on the HUD refers to how many game board moves or turns you have remaining. You will lose the game when your turns reach zero.
