+1 Add One

A small causal game where the objective is to do some basic math.

You will be presented with a 4 digit number, and your goal is to add 1 to each digit as fast as possible.

if you get 4 digits: 7089 then you must input 8190 to get a score.

Input the correct answer, and you get a point. Get it wrong and you lose a point. You got 60 seconds to get as many as possible correct.

Have fun.
