What actually makes an offline puzzle good
I play a lot of puzzle games, and most get deleted within a day. The ones that survive share a few traits. First, they respect your time. No forced waiting, no energy systems dressed up as challenge.
Second, the difficulty curve should teach you. A good puzzle introduces a mechanic in a safe level, then remixes it later so you feel clever for spotting the pattern. Games that just crank up the numbers get boring fast.
Third, and most important for this site, it should fully work offline. If a puzzle needs a connection to save or to show a menu, it fails the basic promise of a game you can play anywhere.
Luxora is a recent example that ticks all three boxes, but the checklist works for any genre. Next time you install something, run it in airplane mode first. You will be surprised how many quietly break.
