When technology and human psychology is used in the best possible way, it works like magic!
You will be shown 21 cards divided in 3 rows. Choose any one card in your mind (do not touch any card) and tap on the row it is in (there is separate button for that).
Our high tech app is trying to figure out which card you look at more affectionately. We currently need around 4 tries to guess your card. So you will be requested to select row your card is in.
You can try to fool the app by pretending to look at some other card but you will fail 999 times out of 1000. Hope you master that look when you cool fool the app.
