About this game

Melpha is a better version of the well-known puzzle game “Mastermind” that hasn’t just a really modern design but is also the only one that has a competitive Multiplayer-Mode besides the classic “Mastermind” mode. There you can test your skills against a friend on your Phone! Both players get the same random colour code and the one who manages to crack the code faster or with less attempts wins the match and gets points. Further you can choose between two other offline modes, on the one hand the Singleplayer, where many challenging levels await you, and on the other hand the Classic Game, which relates to the “Mastermind” board game you might know.

You need both logical thinking and combination ability to crack the code, that means Melpha is the perfect casual game to kill time in combination with fun and training your brain!

For everyone, who doesn’t know “Mastermind” already, here are the summarized rules:

The aim of the game is to crack a four-colour colour code with the minimum number of attempts and in record time!
A code is composed of a combination of five different colours, whereas the same colour can be used more than once.
You have maximum 10 attempts for every code and after every try will be showed how many of your colours were in the code and if some of them were even already on their correct position.

With some puzzling and clever combining of this information, you will always manage to crack the code!

I really dislike the GUI. Instead of showing all 8 colours at once, only 4 are shown, requiring constant scrolling. The combination is annoyingly split in the middle. The combination dots are way too large. The board grows from down to up for some reason. I really hope the dev will make a normal/classic board theme. for now, I uninstalled it.

Love this app, it's simplicity, not too annoying adverts, no pushing "You are great, you have a big head" or similar. There are space to improve the app, as e.g. the contrasts in 8 colour mode, or it would be great if the codes I made a mistake would be marked differently, so I could return to them later again or just see, how many of them were incorrect. All in all, I love it.

Excellent!! the game plays fast and the interface is perfect. All your time goes into thinking about the logic and not the interface. My one suggestion for an addition is to keep a record of the players performance over time, including record fast times and average times as well as average number of guesses per game. I believe the statistical best possible is around 4.3 guesses for a 6 color 4 place game. It would be fun to know how I stacked up.
