Comments on Einstein's riddle for Android

★★★★★ Jessica Hill · Mar 30, 2026
This is the best Einstein's Riddle app available on the Play store that I have found in years! It's also the only version I didn't uninstall. I really enjoy the clean, simple graphics/interface and the options to adjust difficulty settings and fonts is great. I usually play logic grid puzzles but this is the only other game (also called the Zebra 🦓 puzzle) that uses logic deduction from a list of clever clues to solve that I really like. The auto notes are so helpful too! Thank you! 🙏🏽😊
★★★★★ Mar · Nov 29, 2023
Definitely better than most einstein riddle games. I've tried several and this is one of the few that I didn't delete. All games ARE Solvable, despite what some other reviews may say. If someone couldn't solve them, it was by No Fault of this game; it was the player that must have gotten confused. I've never had one that couldn't be solved. Good game if you like einstein riddles.
★★★★★ BooSjhe · Aug 1, 2022
Exceptional game 🙂. The developer is outstanding. Extremely helpful, thanks Alex 🙂. Hard starting over due to failing to save phone backup, but am I working my way back up to where I originally was. I highly recommend this game. Put your thinking caps on. Even with clues it can be challenging at times. I love this game. Love its offline, love the chalkboard layout. Love the puzzles are endless. Best game of its kind so far. 10 starz.
★☆☆☆☆ JessicaDawn Baker · Jun 8, 2019
I want my money back since I wasted it downloading this app to use it 1 time for 10 minutes before I discovered that it's terrible and almost impossible since it does not have enough helpful clues, no way to mark out or erase listed items that do not go with that column. Fix those two things, and I'll try the app again, unless you charge me again to reinstall it.
★☆☆☆☆ Keira Hudson · Jun 17, 2018
There is no way to mark what you eliminate. It is useless without that ability.
