- The solution can be read out of a rectangular grid, where some positions are filled, and some are empty.
- The width of the grid is greater than the height.
- The number you get when you multiply the width and the height is greater than when you add them together.
- The sequence of numbers above decides which positions are full, and which are empty.
- The sequence of numbers actually consists of 69 one-digit numbers, and 6 two-digit numbers.
- When filling in the grid, you start at the upper left corner and proceed to the right. When you reach the end of the line, you start to the left of the next line. (Just like reading).
- All lines in the grid start and end with filled positions.
- As long as you stay on the same line, the numbers alternately represent the number of full and empty positions.
- If you name the 6 two-digit numbers A, B, C, D, E and F from left to right, A=F, C=D=E and A+B+C+D+E+F=99.
