Best logic puzzle game!

I love logic puzzles and I’ve tried all of the ones currently available in the App Store. This one is by far the best! It has a simple, non distracting interface; I like that the clues are displayed all at once in a list form (in some logic puzzle apps, the clues appear one at a time and that’s sluggish and annoying). It’s easy to cross off the clues you already solved. The puzzle grid is on a separate “page” but is easily accessible with a swipe up or swipe down. I’m still on the free version of this app and there are still many left to do at all different levels. The levels are challenging and fun. Once my free puzzles are solved, I’m going to subscribe to access more.

In short, if you love logic puzzles that are fun and challenging, and you like an attractive, intuitive, non distracting interface, you should down load this app. I’ve tried them all and I highly recommend this one to be your main logic puzzle app. It is truly the best one in the store!

I like but…..

I really like this app for a couple reasons. It has 7x7 grids which are hard to find within the logic puzzling community. I also enjoy the challenging level and the graphics. This being said, there are a couple user interface issues that ruin it for me. For one, when you select a correct answer, the other boxes in that row and column are automatically changed to wrong. This would be a useful feature, except when undoing the correct answer, the now “wrong” boxes do not automatically turn blank. This can be frustrating because I now have to go back and undo each one, causing more now “wrong” answers, and because I also now don’t know which X’s I put there previously. In addition, I wish there was a zoom feature, as it’s hard to click smaller boxes and mistaken clicks can easily mess up your game. All in all, I enjoyed playing this game and I think it was manufactured very thoughtfully. The puzzles were very intriguing and I think with just a couple improvements, this game could really beat out all others on the market!

Developer Response ,

Good news, there are solutions to both of these thoughtfully raised issues. Zoom is already there. Just pinch-expand in the grid, just as you would a photo, and it will grow and shrink. It can be helpful to tap on a label on each axis first to highlight the area you wish to zoom. If you mark a box as correct and it auto-fills in the incorrect cells too, but then you change your mind, tap undo twice. Undo will go back many many turns and includes the auto-fill items. That said, perhaps you want to undo an auto-fill after many other changes that you want to keep. Hmm, I’ll have to ponder that one 🤔. Thanks for the detailed feedback. You can also reach me directly via support@eggheadgames.com. Cheers, Michael

Then I highly recommend this one for the following reasons:

1) I like how they start off fairly simple and gradually get harder as you go along. I personally like this method because you get eased in to the harder puzzles.

2) Early on I thought there was an error with one of the clues (which ended up just being me mis-reading the sentence...frustrating mistake on my part, grrr). Anyways, the developer was quick to reply, was super helpful, and it was abundantly clear that he cares a lot about the app. Even though I was mistaken and thought there could possibly be an error, the puzzles truly don’t have them- which means that you won’t get 3/4 of the way through a puzzle only to find out you can’t solve it because the clues all contradict each other.

3) how often do you play a free puzzle without ads? I mean, seriously...NO ADS!! The developer specifically says he “doesn’t like them” which is why we don’t have to deal with them and how awesome is that?!

These are just 3 quick reasons why I will not only continue playing the free part of this app but will support the app monetarily as well.

I’m not being paid to write this nor do I work for or with the developer. I just like to promote great apps when I come across them, and it’s not every day that I find apps that are worth the time to promote.

If you like logic puzzles I can’t recommend this app highly enough!!!
