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!

Had this for years. Great app...1000s of levels. I have no ads (but I may have paid for that & forgotten - if I did, it was worth every penny.) I've lost all progress since moving to a new phone - the easy ones are MUCH too easy for me after all this time, but I can scroll to the more challenging levels without having to play through all the boring preceding ones. Brilliant app - rare to find something brilliant that stays brilliant. Congrats & huge thanks to the developers.

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.
