## What is Invertigo?

Invertigo is the ultimate test of your speed and your sight. Mixing changing colors with changing letters, your eyes and mind will soon start to disagree.

The objective is simple: tap the square whose color matches its letter before the time runs out. G for green, B for blue, O for orange, etc.

It seems simple enough. But as time goes on, and the number of squares grows, you will find your eyes being slowly overwhelmed....unless you've got what it takes to win!

Invertigo has full support for English, Spanish, Italian, French, Chinese, Japanese, and Hebrew. With more languages on the way!

### 5/5 — best game ever

*2021-02-01*

so simple. so perfect. i’ve had this game on my phone for years and it’s just so simple and quick yet stimulating and fun. 

i would love a few extra things like a difficulty level to control how many colors are in the mix . or maybe a “practice mode” where there’s no timer and you can just go infinitely (at max grid). last update was a year ago so probably no hope for more stuff. but i can respect the purity of the app as it is. i’ll never delete. thx <3
