It gets harder as the week progresses. Meaning Monday is the easiest, and Sunday is the hardest.

It should be hard irrespective of day or week so that beginers in chess can learn and advanced solve then

the daily puzzle is more symbolic than anything, usually composed of interesting ideas and themes. It's more about that than 'learning' which beginners can do through normal puzzles anyhoo.

3 daily puzzles every day? This is too much effort. The puzzles go from monday to sunday with rising difficulty, so you should be able to solve at least one of them. If not, also fine. You don’t have to solve them, just try them and you have the same results.
