// There are 2 players and players take turns.
// When a player clicks Submit, the game rolls 2 dice and shows the dice rolls, for example 3 and 6.
// The player picks the order of the dice they want. For example, if they wanted the number 63, they would specify that the 2nd dice goes first.
// You can choose how the player specifies dice order.
// After both players have rolled and chosen dice order, the player with the higher combined number wins.

// Score
// Keep score for each player. The score is the running sum of all numbers that player has generated so far. This means there is no permanent winner, only a temporary leader.
