Akari: Light Up Logic Puzzles

Akari (also known as Light Up) is a calm logic puzzle: place lanterns until every open cell glows, but never let two lanterns shine on each other. Numbered walls tell you exactly how many lanterns touch them.

Every Akari board has exactly one solution and can be solved by deduction alone. No guessing, no luck - just a quiet moment of logic.
