Fun game, reliable app, I enjoy playing Insane level which requires more layers of deduction. I like Multiplayer function, but I suspect that the "random player" is actually "the computer" because the opponent always inputs very random colors and never learns or wins. I play with a friend by typing in a code. We treat it as a cooperative game where we are racing the clock rather than competing against each other. Wordle (similar but w/ letters) reminded me of Mastermind, which brought me here :)

It's a tremendous drawback that a player can't see all of the rows at once, but only a max of seven. Some of the tougher puzzles take many more rows than that. You need to have a split screen option so that all rows can be seen at once.

A good simple puzzle game. I don't like that I have to go in order from first to last every time instead of placing the colors when I get them figured out, but that might be part of the game rules.

Mastermind at its best. Been playing Wordle and remembered playing the tiny board version of mastermind when I was a kid. This is more challenging to me than Wordle but the exact same concept. Enjoy!

Fun, quick logic puzzles, well executed. May not keep it though, if I can't purchase an ad-free version.

This is a great implementation of a classic game of logic; the best I've seen, with one exception, it needs an option to zoom out a bit. The starting rows scroll off the page much too soon. You can scroll up and down to see what you've done, but that's not the same as being able to see the whole board. I recognize the limits given a mobile app, but it's currently too limited. If a zoom setting too difficult to implement, perhaps a temporary toggle to a full board view is an option. 5¤ thn I thk

4 of 5 stars cause I think the app needs 1 improvement -- the ability for the player to hide or delete previous rows. On difficult solutions the useful rows are spread too far apart. It becomes very confusing to scroll up and down trying to find these rows. I end up writing down the rows which will help solve the puzzle. This takes a lot more time, and I lose interest in playing the app very quickly. Or I don't have any paper handy so I close the app. Hope you can add this to the app.

I've finally played through all the levels. Good, quiet thinking game. Simple, effective interface. Even though I've "finished" the game, I just paid for no ads version as reward for excellent program. I will start over and play through again. It's not like you can memorize 3 x 480 games. Highly recommended!

Great implementation of a classic game. I recommend it highly. Here are some suggestions to improve gameplay: -Allow selection of positions, so we don't have to fill the puzzle from the left on every guess. -Allow resetting the current level, with a reset counter for the current solve. -Provide pattern or texture overlays for color-vision-impaired players to apply to the colored balls, to help distinguish them. -Add a "very easy" category for children or the easily intimidated

I find the puzzle range in difficulty even within each level which makes it more challenging. I have always liked this game but it is not inclusive. Is it possible to change the pegs to different shapes aswell? My partner is colour blind and can't participate for the sole reason that they are all circle pegs. Otherwise, good fun.

This game runs smoothly on my huawei android phone. I am impressed that there are few adverts and those that do pop up are only on screen for a maximum of five seconds. This is impressive for a free game. I am enjoying the game a great deal and I'm racing against the clock, though others might choose to challenge themselves to solve in the shortest number of attempts.

These games we used to play some 25 years back with real objects. The digital format is very handy with same delight.

Fun game. Ran into a bug in multiplayer. 1. Put down several dots. 2. Hold one dot (e.g. red) until the timer runs out (was dragging it but ran out of time). 3. The opponent's turn will begin. My red dot will stay floating out of position not in a spot. 4. My turn begins. The red dot is still floating and cannot be dragged. The original row of dot choices at the bottom palette row does not contain red, just an empty spot.

Only installed the game 10 mins ago, and already asking me to rate 5 stars. So far, I'm enjoying it, though it would be nice to see all the rows without scrolling. If I change my mind, I'll edit this review

Really like the game, but in my opinion there are too few easy levels. Even the "easy mode" has levels in it with 5 pins, which is way harder than 4 pins. Also the medium and hard mode include double colors or empty spaces, which is (to me) basically impossible to solve.

Loved this as a board game when I was a child. Really glad to play it electronically anytime and anywhere. This app plays beautifully. Helps keep the mind sharp. Great job developers.

I have loved mastermind since I was 12, so a bit biased. The play levels are great as they add difficulty. The old peg board table top game was limited that way. I haven't played multiplayer yet. Best of all, I will never have to pick up 2,000 little pegs if I drop the phone unlike the original... some 40 times.

Didn't quite enjoy the interface and graphics of the game. The response to touch time is also quite unsatisfactory. Also, in multiplayer games, it's unfair to the player that goes first since the first guess is literally a blind guess and the player that goes next gets an advantage based on the first player's guess. Hopefully the developers will make improvements soon enough.

Good game, however, it crashes during ads on my Chrombook. The only complaint about the format is that it is difficult to scroll down to see past selections. I wish the designers would make a "zoom out" function. I'm still wasting a lot of time on this. It is one of the best games for when you are waiting around, and may need to put it away quickly.

An issue in multiplayer games. I won all games so far. But record isn't accurate. It shows 19 played 11 won. How come this happened when I won all multiplayer games? It also looks like there is no human players even tho it says it is multiplayer mode. Because all games was so easy, in fact opponent didn't even get close to a win. Looks like a bot trying random patterns.

Absolutely fantastic! I used to love the boardgame just like this called mastermind when I was a kid and this is just as brilliant!😀

Mic. O. Sep 3, 2020     

The game works well and is true to the original what I don't like is having to back out of two screens to get rid of the game. Also the free version has some really annoying advertisements to games that are unrelated and would not be something that I would play.

Challenging but oh so rewarding when each puzzle is resolved. Enjoyable game.

Mic. K. Sep 30, 2018     

Just like the old board game, fun! A real thinker and code breaker challenge. I jumped into medium level, which played the same, but the easy level has restrictions which, for me, messes with any kind of strategy you may have been used to employing with the board game.

Pretty decent I guess, would be better if there was a way to play multiplayer with one person as The Mastermind and the other one as the guesser. Also I can't find a way to turn the pesky timer off, that thing is so annoying it makes me not want to play at all.
