To play: grab the numbers as they fall, and drop them into the grid.
If the number turns red, it's wrong.
If the number turns green, it's correct.
If the number turns yellow, then it's one digit off. The correct number is one number higher or lower.
When every green box has a green number, the level is complete.
Watch out for /tmp numbers - these fade away after a few seconds.
