Zero Twenty One

Have fun with this fun remake of the classic solitaire game in Zero Twenty One! Your mission is deceptively simple. You must try to get rid of all the cards at the top of the screen by wisely choosing the ones that add up and the ones that subtract at the bottom, so that they all add up to less than 21 or more than 0.

It's harder than it looks, but really a lot of fun! Test your math skills and mental arithmetic agility and have fun while relaxing after a hard day at work. Will you be able to complete all the levels? Good luck...
