5 stars: The reviewers who have given this game bad ratings apparently never bothered to check out the options. Most variants of the game are included here. The game interface is faithful to the Invicta classic table version, the controls are easy to understand, it's easy to remove and trade pieces on the board before pressing
5 stars: Very challenging, but addicting. There is good diversity of settings to play with to title the game's difficulty. The times challenges are very hard to do before you get really good and far at the game, but one can figure out a system.
4 stars: Exactly what it says on the tin! Classic, fun logic game.
4 stars: It's hard. Engages the mind. Is not the kind of game to play while watching TV or listening to a book on tape.
3 stars: Disappointed at the two usage limit per color, used to solving 5 peg mastermind by starting with 2:3 combo, stults entire procedure ongoing from there. Had hopes, but I guess I'll keep looking.
3 stars: The board version allows two colors on each setting. I prefer that way.
2 stars: No ability to change your mind before querying the app, other useful options missing as well.
