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.

Exactly what I was looking for! Ads are getting so bad, it's sometimes an exercise of logic just to figure out how to get past them and back to the game. I'm tired of apps requiring access to things that have nothing to do with the app. Collecting data, interrupting app use, requiring you to be online. I would gladly pay a small amount for a game but don't want a subscription. I just want to play a simple game that is self contained. these fit the bill perfectly! I absolutely love these games!

Great variety of puzzles, extensive options for difficulty, no ads or arbitrary daily limits, no micro transactions, no need for wifi, just pure puzzling. Visuals are utilitarian, but that is good, everything is very clear. Input is intuitive, may not have as much QoL as dedicated single puzzle apps for things like sudoku, but it's certainly close and I have never felt frustrated or restricted by the controls. I could not reasonably ask for more from a free app. Overall a wonderful experience.
