I keep having to delete the app and re-add it. It’s a pain in the neck. Other than that, I enjoy the app. ### 5/5 — Great for learning to memorize! Great for memory exercise! *2020-03-16, version 1.2* just like the real deal when i was 4 yrs old & played by myself with a pack of cards. This game seriously helped me learn how to remember. Every kid & aging adult should play this everyday!!!!! Still so much fun!!! But....pairs should not need to match! ### 5/5 — Awesome app *2018-11-12, version 1.2* Perfect way to while away hours or just a few minutes. I usually play solitaire, but this has become my new favorite game, although I do toggle back and forth between the two apps. I highly recommend it! 😁❤️ ### 5/5 — Fun beautiful memory game *2013-11-24, version 1.0* Gorgeous version of a classic game with a few new twists. Love being able to set the number of cards and playing in dual iPad mode is a blast. I also like that it is a fun non violent game suitable for all members of the family. ### 4/5 — Very nice   *2013-11-05, version 1.0* Simple awesome to the point game but there got to be music or sound control settings! ### 5/5 — Can't stop playing this game!! *2013-10-30, version 1.0* This game is sooo much fun! It's simply addicting! Beautifully designed. Very intuitive. I need more hours in the day… ### 5/5 — I play like a woodpecker. *2013-10-28, version 1.0* I can't remember my credit card number. How can I remember the position of 16 cards? My brain hurts. ### 5/5 — Beautiful cards, animation, and sound *2013-10-27, version 1.0* You’ll want to play this with a friend, and the two-iPad mode is great for groups. ### 5/5 — Bravo! *2013-10-25, version 1.0* This game has been beautifully designed! It is fun to play by yourself and with friends. Playing on 2 iPads as one playing surface is amazing! Try throwing cards from one iPad to the other iPad and be prepared to have your mind blown! How did they make this possible???!!! Wow!!! ### 5/5 — Starts easy then gets challenging *2013-10-25, version 1.0* Very nice implementation of the classic memory game but with a tablet twist. Starts with 16 cards then gets progressively harder when you hit 54 at a time. Head-to-head mode against others makes it more social. And then there's the cool dual-ipad mode where your play area spans two devices and you can drag and throw cards across both screens. My 8yo & 3yo like it too. ## Frequently asked questions about Concentration ### What is Concentration? Concentration is a classic card game designed to exercise your short-term memory.
