Here is, with a certain interval, randomly appear the numbers from 1 to 255. You need to convert these numbers into binary code by changing 0 to 1 or vice versa.
Points are added for correctly entered binary code. For bonus flashing ranks you can get twice more points if you have solved it till it is flashing. The more points you get, the less time you have before the next number appears.
