Gridsmith Puzzles

Gridsmith Puzzles is a big pack of grid-based logic puzzles that grow in complexity as you go. Think number and pattern deduction, the kind of thing you chip away at while your brain wakes up. It's all stored locally, so it's my go-to for offline downtime.

The difficulty curve is well judged. Early boards teach you the rules without hand-holding, and by the later packs you're actually taking notes in your head. A clean hint system helps if you get stuck without just handing you the answer.

No ads mid-puzzle, no forced online check-ins. It respects your time, and there's a huge amount of content to work through.
