What counts as a logic puzzle?

A logic puzzle is one you can solve through deduction alone — no guessing, no luck, and no outside knowledge required. The information you need is all on the board; the skill is in how you process it.

Sudoku is the classic example: every digit can be deduced from the ones already placed. Unfold is logic in a spatial domain — you’re deducing where holes will appear by mentally reversing a sequence of folds.

Why logic puzzles feel so good

Every deduction cascades. Solve one cell in Sudoku and it narrows the options for a dozen others. Get one fold right in Unfold and the rest clicks into place. That cascading-certainty feeling is the core reward of logic puzzles — and it’s different from the “trying to remember” reward of trivia or the “search for words” reward of word games.

Which level should I start with?

Start with Sudoku Easy if you're new. It solves through simple scanning with no pencil marks. Once that feels quick (under 4 min), try Sudoku Medium or Unfold Easy. Hard levels are genuinely hard — don't feel bad if they take 20+ minutes. The techniques are all documented in the Sudoku guide and Unfold guide.
