Consecutive Quads - Puzzle

Consecutive Quads is a number logic puzzle where every row and column must contain each number exactly once. The challenge comes from special clues placed between cells. Every dot belongs to the four surrounding cells in a 2×2 area and reveals information about consecutive numbers inside that quad. Consecutive numbers are numbers next to each other in value, such as 1-2, 2-3, 3-4, or 4-5. White dots mean the surrounding 2×2 area contains exactly one consecutive pair. Black dots mean the surrounding 2×2 area contains two or more consecutive pairs. Areas without dots give no clue. Pairs can appear horizontally, vertically, or diagonally inside the quad, creating a unique style of deduction that mixes number placement, pattern recognition, and logical reasoning. Start with smaller grids and work your way toward larger and more challenging puzzles. Every puzzle is designed to be solved through logic and careful observation.
