When the New York Times was testing its new game, Connections, it was also testing out another game called Digits. In this game, you were givin 6 numbers and a goal, and had to reach it by combining numbers with the 4 operators, like countdown.
Originally, I was just goin to make a clone of digits, so that I could play it all I want, but I came up with my own thing.
In this game, your given a list of operators, and you have to place the numbers in the correct order to move on to the more difficult levels. You can't use a number more than once, and you only need to use as many numbers as there are spaces(?).
I started making it more polished, but when you move on tot he next level, it's sudden, but I started working on other projects so I decided to put this one under the bed.
