27 medium puzzles (10×10, 12×12, 7×7) to solve.
Medium Akari puzzles use 10×10 grids with more walls and numbered constraints. They require multi-step reasoning — you'll often need to deduce bulb placements from wall numbers before filling in the rest.
Place light bulbs on empty cells so that every white cell is illuminated. Light travels in straight lines until it hits a wall. No two bulbs may shine on each other. Numbers on walls indicate how many bulbs sit adjacent to that wall.
