## Description

Add One is inspired by an exercise in Daniel Kahneman&#39;s book Thinking, Fast and Slow.<br>The principle of the exercise is simple: First you read four individual digits, you have to remember them and increase each individual digit by one.<br><br>Currently there is only one static game mode. Four randomly generated digits are displayed one second apart. After a short pause, you have to enter the digits increased by one again at intervals of one second.<br><br>There are still many expansions planned for the game.<br>For example:<br>* Configure pause time<br>* Change the number of digits<br>* Change how much you have to increase each digit (+3 instead of +1)
