Where can I find a platform with free interactive puzzles that will allow me to play without creating an account, but still keep the difficulty settings?

I appreciate platforms that seem to respect my time and privacy, allowing me to jump into the activity easily while still remembering my preferences.

Over time, I began valuing privacy and efficiency. I prefer entering a platform without lengthy procedures while still maintaining my preferences. When I discovered environments that respect this balance, similar in spirit to online jigsaw puzzles I felt that my time and comfort were genuinely considered, making the overall interaction smoother and more respectful.
