Comments on Einstein's secret book for Android

★★★★★ A S · Feb 12, 2020

I really love the game. It does help you to improve your overall knowledge. The puzzles are fascinating. Some of them are really challenging. It also has some interesting information about the Einstein. Although the game control could have been better. But overall an interesting game.

This is the best game I've played, it should be done with other scientist as well 1000 stars

★★★★★ Lavanya nee · Sep 29, 2020

Oh my God. Really that was amazing to me. This game is really tough especially the photoelectric level. I used the heart for this. By the way there is only 1 heart to use, if you are going to download this game then keep it in your mind that don't use that one and only heart before passing 5th chapter. New things, new facts to know. I had got stuck at the level chess towers but this one is too easy after finally finishing the level. Okay... Okay... a lot ... Go and download, may sure that you 😆

Script makes it hard to read. Got to level 3 and quit. Too much repetition. Tedious rather than challenging.
