User reviews

Thinking can be tough!!!

The first time I played this I was hooked. The first time I ever got a one shot cleanup I was on top of the world, ma! Some of these look so simple until you’re left with 3 or 4 hanging. Good luck!

Fun, addictive

Lots of fun - takes a bit to figure out some of the levels (which I enjoy) but there is a “style” (if you will) that ultimately you will notice/see after 20-30 minutes. Perfect for those of us who want to just quickly go deep into a fun puzzle based game.

O N O

Great brain fog game. I play it for a few minutes in the morning to crank my ADHD brain up for work.

Mind challenging

Great game. Keeps the ole mind working.

Awesome game!

So much fun! Easy to get started and segue to more challenging levels. Great for kids.
