The new ads made this 5 star game into 1 star. The issue is I screenshot when I've finished with all the clues from one line. I then start another line using the screenshot to transfer solved clues. The game now inserts an ad every other time you exit. Trying to remember the solved clues when you're having to wait for an ad makes the game a pain.

Slight learning curve might have been averted by looking at the directions, which I didn't. But once you know what the filters are for, how + and neg hints are green and red when they come up (respectively), a great little game & nice change from word logic puzzles. I've enjoyed it, but I haven't tried the more extreme levels. My only mild complaint is how tiny the icons are on a phone screen, but you can zoom in if you can't tell it is. I also wish there were more categories, but still love it!

This game has SO many levels to play, in multiple categories that fit whatever type of puzzle you want to play from easy to insane. I like the tile pictures the most; cute, simple and easy to see compared to other games that use text. All the puzzles are nice and challenging and with how many there are it's gonna take forever to get through just one category.

I first found this game in 2021, and it's now almost the new year 2025. And this is still one of my top three favorite logic puzzle games. I love Einstein/Zebra riddle games but word clues confuse me after playing for a bit. I love that I can focus on the images instead of written clues, as well as how this is laid out compared to other versions. The five difficulty levels are a plus as well.

I play this game every day to help keep my brain sharper than it would be otherwise. It offers up some challenges, and that's what I want in a brain game! I use the option to shut off some of the clues, almost always, because it helps me to focus more. I really like that it's offline and not like the games that want you to compete and you aren't playing for anything other than yourself! I only wish it had a bit more sophisticated looking things for the items and not be quite so childlike.

I enjoyed the game; it was fun and engaging. However, the excessive ads were a drawback. Accidentally clicking something often triggered another wave of ads, making the experience feel too pushy. Overall, it's a great game that helps you think, but the aggressive advertising takes away from the enjoyment.
