If you like this style of puzzle, I highly recommend Simon Tatham's Puzzles on android (https://play.google.com/store/apps/details?id=name.boyle.chr...). It has implementations of a dozen or so puzzles including a domino puzzle not unlike this one. And it has no ads or microtransactions to boot.

Simon Tatham's puzzles are also available on the web on his site:

Some time ago I found this implementation: https://medmunds.github.io/puzzles/ I think it has a more pleasant ui.

I love this. The app is less than 4MB and with so many puzzle types!

I see it as a kind of "perfect app" in that it does what it sets out to do very well and does exactly nothing else. If only all mobile games were the same...
