This is a game called "shut the box." It is a real game I have played before. How you play is you roll a random number between 2 and 12 (like you are rolling dice). Then you click on any combination of numbers that adds up to your given number (if a number is red it is being selected). You can only use each number once. Once you have your combination, you click submit or press enter. It will tell you if it is valid or not and if it is, it will delete the selected numbers and give you a new number, restarting the cycle. If your answer is not valid, it will ask you if you think it is impossible to make the given number with only the remaining numbers. If you say no, you can keep trying with that number. If you say yes, then the game ends and the number of tiles left is your score. Lowest score wins.
