Ratings and reviews

Free with no ads. No timed games, so great to do the various puzzles at one's own pace. There're no achievements (like win streaks or number of levels done, etc) that get recorded, but really, is that needed? Nope. Gives mse something to do when I'm bored (whether it's the mindless easy levels, or the higher levels that require thinking, or the easy-to-figure-out but require-many-taps puzzles). Wish I can make extra marks on tiles in Dominosa to keep progressive on when I'm guessing.

I've had this app installed for years, across many phones. There's tons of games but I mostly play the nonograms (called "Pattern" within this app). I love love love that I can dictate the size, and it autogenerates an endless supply of puzzles. I've never been a fan of picture nonograms; the randomness of the generated games is much more interesting and challenging. I'm obsessed. I also sometimes play sudoku (a classic). Even if you only play one puzzle this app is great. THERE'S. NO. ADS! 👍

I can't believe I never reviewed this. I've been using this app for at least two years. It is perfect. Free, no ads, great games, credits and information provided on each game (which I LOVE) good simple design. Just perfect. I could not be more grateful to the creators, I have anxiety and intrusive thoughts so I often use puzzles to calm. Sometimes Pearl freezes for a long time so it takes repeated attempts to get it to generate really large grids. But no problem with any of the standard sizes.
