Fünf Sterne für eine regelbare Lautstärke, derzeit gibt es nur an oder aus. ### 3/5 — Problems *2025-06-06, version 2.9.2* I like the game, but there is a problem when I choose to play color game and for example the text is gray when I click X it says game over. ### 3/5 — Color Match *2024-10-16, version 2.8.1* I didn't see a tutorial. ### 4/5 — Awesome *2024-10-04* Such a good game, really gets me thinking. There is just one probelm. With the new update, I can't use my arrow keys on Mac. It works using the cursor, but I'm not sure what happened because this only started to happen after I did the last update. Other than this, it's so awesome, I have it on my phone and laptop so I can play it anywhere. I love it! ### 3/5 — lol *2024-04-18, version 2.8* hard but fun kide of good game good time wastor ### 2/5 — Not appropriate for non touch screens *2024-03-27, version 2.8* It isn't possible to move the curser quickly enough. With some adjusting it would be much better. ### 2/5 — TIMES UP *2024-02-15, version 2.8* It's good apart from the annoying fact that it constantly pops up Time Up after just a few clicks. At this rate it's purpose is to test your patience rather than intellect. ### 3/5 — Claudia *2024-02-01, version 2.8* wish it has more instructions ### 4/5 — Improvement *2023-11-24* It is a nice brain game, but something more can be added to make some integration. ### 4/5 — Good *2023-01-28, version 2.8* Good for a free game ### 1/5 — NEED MORE TIME *2023-01-23, version 2.8* NEED MORE TIME ALSO NEED MORE QUESTIONS TOO BORIIIIIIIIIIIIIIIIIIIIIING ### 1/5 — No way to improve *2023-01-04* I hope the developer will add a way to adjust the time to reply. People with ADHD, etc. can have a really hard time answering within one second. So do people with other intellectual or physical disabilities. This game would be a great tool for developing better mental and physical dexterity, but right now it's impossible. Thanks. ### 4/5 — Brain *2022-11-21* Test ## Most critical reviews (10 lowest-rated) ### 1/5 — meh *2026-05-25, version 2.9.8* meh ### 1/5 — Disappointing *2026-01-04* Click on the correct/ck mark and it doesn’t register and counts it wrong. Removing the game. I want a game that you can actually play and be challenged correctly! **Developer response:** We checked the code carefully and could not detect any bug in the game. ### 1/5 — Ruined *2025-06-16, version 2.8.1* Would have recommended the game before the game was updated to not be able to use the arrows on the keyboard. If this is a bug please fix and id be glad to redownload ### 1/5 — Not good for MAC *2024-08-30, version 2.8.1* If you're playing this on a Macbook or any kind of laptop that does not have a touchscreen, this is too fast if you're not pinpoint accurate with your mouse or mousepad... or maybe I'm just too slow. ### 1/5 — mimi *2024-04-07, version 2.8* good ### 1/5 — Great *2024-03-20, version 2.8* If it worked !!!!! ### 1/5 — Dreadfully poor *2024-03-12, version 2.8* The game has no facility toadjust difficulty levels. The time 'allowed' for submission of an answer is ridiculously short. A very poor game and a waste of time - it will be deleted immediately. Very telling, when trying to submit this comment, is the fact that 'nicknames' such as Useless, Pathetic, and Awful have all been used before ! That tells you something. In fact, i've just discovered that NO WORDS ARE AVAILABLE ! Obviously don't want to know just how pathetic this game is ### 1/5 — one brain *2023-08-14, version 2.8* confusing! doesn't score properly. No matter which I choose, I get the same score. Need directions ### 1/5 — grrrrr *2023-07-30, version 2.8* make the timer a little bit longer ### 1/5 — 🤬🤬 0Rating!! *2023-06-01* What the deal with the popups!!! There annoying!!! STOP THE FREAKING POPUPS!!! **Developer response:** We're a small business and we make money by running ads. You can remove ads permanently for a tiny one-time fee - look for the button in the main menu. ## Most praised reviews (10 highest-rated) ### 5/5 — My opinion *2026-06-02* Its the best game ever kinda hard though ### 5/5 — Sooo fun *2025-08-28, version 2.9.8* It's really good ### 5/5 — Redownloaded *2025-07-30, version 2.9.8* The app does what it needs to do ### 5/5 — Timer setting *2024-09-30, version 2.9.2* I actually think it's great: simple, sleek design and to the point. But I think it would be better if you had the option to set the timer individually. Every time you exceed the time by a minisecond, the game stops and I find that much more annoying than the advertising interruption. Instead of stopping, a signal could also sound. That would also be incentive enough to play the game fast enough to avoid the sound. ### 5/5 — Excellent ! *2024-08-21* Perfect for rehabilitation, comes at a very good price. I recommand ### 5/5 — COOL GAME! *2023-06-12, version 2.8* VERY NICE ### 5/5 — - *2023-04-14, version 2.8* - ### 5/5 — mouse *2022-06-13* Brain games are really important . It's important to make them fun too so you keep coming back:) These are fun ### 5/5 — Give me Challenge *2022-05-21* Funny ### 5/5 — War eine super erfahrung *2022-05-15, version 2.8* toll --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
