Lone Sevens is a solitaire game inspired by and using the components from Stephen Glenn's Rattlebones, published by Rio Grande Games. Players roll five dice, trying to come up with a set of dice totaling seven, for which victory points are awarded - replacing one of the used die faces. One unused die face may also be incremented or decremented by one. If no sevens are rolled, one die face must be replaced by a miss token; one other showing face may still be incremented or decremented. Once three miss tokens are placed, the game is over; the victory point faces are totaled. -description from designer
