In a recent study, Kateryna Afinogenova found that almost seven percent of the kids in her test group could do bitwise operations and convert to and from hexadecimals.

The goal of this game is to allow kids to do the same thing. The concept is simple: you need to move your cursor to the left or right and press the buttons to convert from one number to another.

You will be shown a number and you need to convert it to the desired one.

It is recommended to use Chrome or Safari browsers. The game is available in English, Russian and Ukrainian languages.
