- Numbers Up is a quick casual game that is fun and challenging. Each turn rolls 5 dice from which you choose 2 pairs to play and 1 to discard. But choose your 2 pairs carefully! The sum of each pair selects a Number to move. Each Number will first lose points when moved off the starting row. Then try to keep moving your Numbers Up the board to gain points. - Keep an eye on your Discard Rows because they will lose a position when you discard the remaining die after choosing your 2 pairs. When a Discard takes the last position available in that row, the game is over - whether your score is positive (a win) or negative (a loss). - Track your progress on each of your personal devices separately or compete with your family and friends on Game Center. - Numbers Up offers an exciting blend of skill and luck with fast-paced play you can stop and resume at any time. Use the in-game tutor to learn more details of how to play. Thanks for playing! Your friends at Island Moon Studios - Love our app? ...
