This game tests the player's ability to quickly do mental math.If the player doesn't already know how to convert decimal numbers into binary numbers, the player can click the "Learning Mode" button to see how binary numbers can be broken down and reformed into decimal numbers.
To start a new game, click the "Play Game" button. In play mode, the player must input the binary number which is equivalent to the decimal number being displayed in the current question. Getting a question right awards points based on the game's difficulty setting. After answering five questions, the bonus multiplier is applied to the player's final score.
There are five levels of difficulty which ask for conversions of increasingly larger numbers for increasingly more points.
The bonus multiplier decreases over the course of the game, so quickness is key to getting the best score at the end.
