Like getting a rating. However, app will not load on my iPad. Also, on my phone when there are pop up messages from the game the message is blank and will not clear unless you close the game. Finally, the app gets alerted by the iPhone as being in need of update by the publisher. **Developer response:** I have just released version 3.0 of Ultimate Mastermind HD which is updated to work on the latest versions of iOS. Please check it out and let me know if you have any issues. Apologies for the very long hiatus in getting the app updated. ### 2/5 — Loved it *2016-02-07* It's broken. Since I bought my iphone6 plus, it hangs and crashes on certain attempts on or below 4 (classic game); possibly on wins. The interface is so good, I still play it all the time. Note: My email to the address that appears on the developer page, came back as "no such recipient." We may be orphans. **Developer response:** You are no longer an orphan! I have just released version 3.0 of Ultimate Mastermind HD. Please check it out and let me know if you have any issues. Apologies for the very long hiatus in getting the app updated. ### 2/5 — Mastermind *2015-08-20* Not bad but it keeps freezing especially when you get the right combination early. ### 3/5 — Bueno, pero... *2015-12-27* ¡No funciona en 6s! **Developer response:** I have just released version 3.0 of Ultimate Mastermind HD which is updated to work on the latest versions of iOS.  Please check it out and let me know if you have any issues. Apologies for the very long hiatus in getting the app updated. ### 3/5 — Ok but needs option for blanks *2014-12-08, version 2.0* Plays ok but it would be better if you could leave a number of blanks in the guess. ### 3/5 — Needs an update! *2013-07-05* iPhone 5 screen size at least? **Developer response:** I have just released version 3.0 of Ultimate Mastermind HD which is updated to work on the latest devices and versions of iOS.  Please check it out and let me know if you have any issues. Apologies for the very long hiatus in getting the app updated. ### 4/5 — Doesn’t fill screen *2024-07-31* The game plays well enough but there is so much empty space at the top and bottom, between the two around a third of the screen (iPhone 15 pro max) is just black space. Not a show stopper but seems a waste to not use that space and make things feel less cramped ### 4/5 — Great game! *2014-10-18* Game is great. Lots of great hours of play. Please fix the crash every time I finish a game and click to see the computers solution. It always crashes on the row of the solution. **Developer response:** I have just released version 3.0 of Ultimate Mastermind HD which is updated to work on the latest devices and versions of iOS. Please check it out and let me know if you have any issues. Apologies for the very long hiatus in getting the app updated. ### 4/5 — Great game-a few little bugs. *2014-02-13* This is probably my favorite game. On this latest version, most of the time, when I select the button for the game to solve the puzzle, it "closes" the game. I do this after I have solved a puzzle. The game is still open but when I go back in it opens in an earlier game than the one I had solved. This happens on level 6, I haven't tried it on other levels. Also when I selected the link to email you I got an error message. I play on an iPhone 4S, iOS 7.0.4. Thanks!! **Developer response:** I have just released version 3.0 of Ultimate Mastermind HD which is updated to work on the latest devices and versions of iOS. Please check it out and let me know if you have any issues. Apologies for the very long hiatus in getting the app updated. ## Most praised reviews (5 highest-rated) ### 5/5 — Michael Swan *2023-04-29, version 2.0* Didn't think it was possible to improve on Version 2.0 ### 5/5 — I love Ultimate MM HD *2010-05-30* I loved the iPhone version, but the iPad version is even better. I play at level 7 and while I was looking forward to earning my way up to level 8, I'm now going to try my skills at level 10. ### 5/5 — excelente!!!!!!!!!!!!!! totally worth it!!!! *2010-05-16* This app is so cool and addicting! it's great for your brain, it's fun… what else do you need in a GREAT app? (but maybe it would be better if the board color could change) :) ### 4/5 — Very nice, but... *2010-09-04* This is a nicely done version of Mastermind, but it lacks one feature tha would make it a much more social game: it would be great if there were a way for two people to take turns playing the same computer-generated set of pegs. That would allow friends to compete against each other by taking turns and handing off the iPad or iPhone. If I find another version of Mastermind that does that, I'll probably switch. I'll cross my fingers that this feature makes it into an update. ### 4/5 — Excellent rendition of a classic! *2010-05-15* Extremely well thought-out design focused on ideal usability with a floating peg palette, buttons to easily reuse a row as the new base, easy peg swapping, and an AI teaching mode! This is a must-have app if you like Mastermind! P.S. Once the developer updates the basic board graphics in the next release, it will look as beautiful as it plays, and I will give it 5 stars :) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
