This lovely incarnation of a game we played in the 80s includes more than 6 colors, more than 5 spots to solve, and limitations for the harder levels on using the same color. The hardest level is "Insane," but after some months, there are methods to solve under two minutes with a little luck and multiple tries (no, a real winner doesn't try the same level twice in a row!). Anyway, letting us review our attempts (like it used to do) to train logic should be an option we can turn on in settings😀

For the most part i really like this game and the different levels. It would be nice though to be able to track your best scores or something. The only thing i dont like is that you cant use a color more than once a line in EASY mode. Even though the solution wont have duplicate colors, its helpful to be able to double up as part of your solving strategy.

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

What’s new

- improved the auto scrolling when submitting a new guess. Automatically going to the last played page when selecting a board to play.
- added colorblind mode, and completely remade the game to make it much lighter/faster, if you have any issues let me know at codebreaker@rottzgames.com . Also if you have any improvement suggestions let me know also. Thanks.
