Light Up Akari - PuzzleMonster

Light Up, also known as Akari, is a logic puzzle about lighting the board. You place bulbs that shine down their whole row and column until a wall blocks them, and your goal is to illuminate every white cell. Two bulbs can never see each other, and every numbered wall has to be satisfied exactly.

Features:
• Tap a cell to place or remove a bulb
• Drag across cells to mark them empty with an X, no mode switching
• Light rays spread across the board with a warm glow
• Bulbs that see each other flash red right away
• Numbered wall clues turn green once they're satisfied
• Undo any move with a single tap
• Three difficulty levels: Easy, Medium, Hard
• Pick up right where you left off
• Stats and best times for every difficulty
• Plays fully offline
• No third-party ads, only occasional suggestions for other PuzzleMonster games

A bright, rewarding puzzle that's all about careful deduction. If you enjoy Sudoku, Minesweeper, or grid logic, Light Up is easy to fall into.
