XMille is the cellphone version of the classic card game Mille Bournes.

Mille Bornes, also Mille Bournes, is a French card game. The premise of Mille Bornes is that the players are in a road race. Each “race”, or hand, is usually 700 miles or kilometers long (1000 for the standard 4-player game), but the first player to complete that distance exactly has the option to declare an extension in which case the race becomes 1000 miles, hence the name of the game which means “one thousand milestones”. The object of the game is to reach 5000 points, which normally takes several hands.
