Slow down. All puzzles, even the hardest ones, can be solved logically and without error if you just go slowly, and make full use of your grey ‘x’ to fill in the squares that can’t possibly contain color. It’s a back and forth process that can take a long time. I find that if I absolutely can’t figure out where to move next, I take a break and come back. Suddenly there appears an obvious move that I hadn’t seen before, probably just due to fatigue.

And if your fingers keep causing errors, zoom in. It’s more of a pain, but it helps.

That's what makes it fun to people who like hard puzzles! Most of the puzzles are fairly easy anyway, and u should be able to get 3 stars first time. It would be good to see the average time before you do a puzzle, as it gives you an idea of how hard it is.

Having more room for error in solving larger puzzles makes perfect sense.
