I created an interesting new (free, web-based) puzzle app for mobile devices (works best on iPads, less-well-to-not-at-all on other devices). Want to try some challenging puzzles that blend spatial reasoning and manual dexterity? Just Slide to Unlock! https://slide.isohedral.ca/
@csk This is a great concept and has that addictive "just one more...". Works well on my Pixel 6 (at least up until the double zig-zag. Might have to carry on now I've seen there's 3 finger levels
@mikestreety @csk wait until you get to the 5 finger level! (Guessing that is the highest, but maybe it adds lines infinitely until the final screen which is just a bunch of dots Twister style and you have to touch all at once to win.)
