Lightwell vs ThinkerLoop

Lightwell is a clean logic puzzle inspired by Akari, the Japanese “Light Up” puzzle. Place lights to illuminate the board. Lights shine horizontally and vertically until blocked by a wall. Numbered walls tell you exactly how many lights touch them. Every cell must be lit, and no two lights can see each other. Simple rules. Pure deduction. If you love Sudoku, Minesweeper, Picross, Nonograms, or the daily Mini and Strands, Lightwell was made for you.
