This is a awesome app.

I got this app to help my brain because smarter and stronger and as soon as I started to play this app, I knew that the goal definitely got completed. This game starts off to be a bit challenging with limited time, but immediately starts to make your brain understand it, and start to be able to do it quicker. This game basically is putting one main letter a lot of times (if you chose it that way) and you have to spot the one letter that’s the odd one out. I found this game because my friend had it and said she enjoyed it quite a bit, and I like challenging games so I had to give it a try of course. If you are a very smart person and can finish hard quizzes and puzzles quick, you might not find this hard. But for me I am smart but not one of the smartest people ever. So if you love puzzles and having to spot the odd one out, you should definitely give this game a try! I have an eagle eye so sometimes I can spot the odd one out quickly 😉.

Fun pass time game

The game and how it works is simple. You find the hidden letter, number, or both in a cluster of similar letters or numbers. It is timed, meaning you have to compete the mission with the allotted time frame given in order to achieve 3 stars (to rank your speed of completion) I enjoy this dynamic and I see that it is very well thought out, as simple as it may be. It is fun, time consuming, as well as challenging. Which gives three different, but prominent features which makes this game interesting. However, there is one thing I would recommend. Upon finding the outlasted letter or number in the bunch, I noticed there is a time of non action, as when moving on to the next “level” you don’t do anything but wait for the next “level” or “stage” to make its appearance. When this happens the timer still runs. I feel as if this would make the game much more enjoyable if this feature was removed. Perhaps pausing the timer when completed, until the next level or stage starts. Other than that great game!

This game is literally the best

I love this game it is fun and entertaining (if you enjoy looking for mismatched letters all day) but that’s not the point it really improves your vision and sometimes my brother plays with me after I’ve been playing for a month or so and he hasn’t beat me ONCE and the best part is if the game is hard there is like hundreds of different levels at the same time and there is one mode where you can choose the size of the boars so you can choose how quickly it gets harder which makes it a lot easier. All those people saying one star are WRONG people I think they just don’t enjoy looking for letters but you really should at least try it
