Puzzle Arena

A new logic puzzle every day. Free, no sign-up, and every board has exactly one answer — so there is never anything to guess at.

A Latin square where the clues are signs between squares, not numbers in them.

Place bulbs until every square is lit, and no bulb can see another.

Two symbols, three rules, and no row ever repeating another.

Guess the hidden word. The colours tell you how close each letter is.
