• The game has 2 players, playing in rounds
• In each turn, a player rolls a dice as many times as he whishes.
  Each result get added to his ROUND score
• BUT, if the player rolls a 1, all his ROUND score gets lost.
  After that, it's the next player's turn
• The player can choose to 'Hold', which means that his ROUND score gets added to his GLBAL score.
  After that, it's the next player's turn
• The first player to reach 100 points on GLOBAL score wins the game

PS: You can put another final score for the game. Just put it in the right field at the bottom ;)
