Domino Score Calculator

This calculator handles the three moments in a game of dominoes where somebody has to count. Type the pips showing at the open ends and it scores the play under All Fives, All Threes and Fives and Threes at once, so a table playing any of those variants can read its own line. Type the tiles in a hand and it totals the pips, names the heaviest tile and counts the doubles. Type the pips left when a hand finishes and it gives the score to the winner, whether that is every pip in the other hands, the difference in a blocked game, or the total rounded to the nearest five. House rules differ everywhere, so each answer says which convention produced it.
