Keep your brain trained with Colonumbers!
In each row there are 4 boxes with numbers. At the beginning you have only 0 and 1. Click on the number to change it. Remember that you can transform even numbers to 0, 2, 4, 6 and 8 and odd numbers of course to 1, 3, 5, 7 and 9.
You have to arrange the numbers in ascending order from left to right. You can put only different numbers in the same column to complete the game.
