This is great for kids and adults and anyone!

It is truly great for a kid and Adults too. I absolutely love it and it helps you learn and it helps you see better sometimes. Everyone should get this app on their phone because it helps with your every day life. I bet you every day if you got this app it would help you get smarter and I'll help you do better in school. This should have advertised on TV because it is such a great app. It can make everyone smarter! If I could talk to everyone in this world I would tell you guys to get this app and tell everyone to get it!it also gives you something to do!

...what a great game. Was asked to review it & suggest improvements - which I can't as it's PERFECT. I play EVERY DAY, & I'm 55 😊 Many of the puzzles are VERY challenging & some easy enough to afford a chance to relax till the next hard one. Five stars!!! (Just an afterthought: the ads are a tad annoying. There's an option to remove them but I'm guessing it won't be without charge). SJGRWRB

Update:- Time has gone by since last I played this game, & now I’m playing it ALL OVER AGAIN! It’s still fanTABulous! I LOVE it. Fun. Challenging. Exciting. I’ve tried others like this but this one beats them all. Thank you to the developers 😁

Can' think of one ,


I really enjoy this game, it gives a solid challenge without going nuts. I have concerns on the "strobe" portion of the levels. I have epilepsy and the flashing has started auras so I have not been able to move forward.

Could you possibly give an option to turn that off, like your colorblind option.

Edit: I emailed the creators about this problem and they fixed it. I am incredibly impressed with their service and their app.
