Logic Pro 2 is a 1997 arcade puzzle game developed by Deniam Corp. that takes the familiar mechanics of nonograms (picross) and injects them with arcade urgency. Rather than peacefully solving puzzles at your own pace, you must complete the picture grids while fending off active enemies that roam the board, erasing your carefully placed marks and blocking your view of the number clues.
How to Play
The goal is to reveal a hidden picture by filling in the correct squares on the grid, using the numerical clues on the edges to determine how many consecutive filled squares are in each row and column. Insert a virtual coin with Shift and press Enter to start. Use the arrow keys to navigate the grid, Z to fill a square, and X to mark a known empty space with a cross. You must solve the puzzle before the timer runs out while dealing with enemy interference.
Tips
- Anchor your puzzle: Always start by filling in rows or columns with numbers that take up the entire length of the grid, or combinations of numbers that leave only one possible arrangement.
- Use crosses defensively: Marking squares that are definitely empty with an ‘X’ is crucial, as it narrows down your options and helps you quickly recover if an enemy erases some of your progress.
