The grid will be filled with blank spaces and it is your job to use logic to figure out how to put the given numbers into the grid so they all fit. It's like a crossword puzzle, but with numbers instead of words.
No need to worry if you get stuck - the app will not accept incorrect inputs, and on your first mistake will fill in a cell to give you a hint. Finish the puzzle in the fastest time possible, then challenge your friends to beat your best time.
To play, press one of the numbers to the right of the play field then touch the square where you think the first digit of the number should go. You may also use the arrow keys in conjunction with the Tab and Enter/Return keys.
