Multiplication Table Puzzle

📖 Overview

Multiplication Table Puzzle is a math-based logic game. You are presented with a multiplication grid where some numbers are hidden. Your goal is to fill in all the missing values using logical deduction. The grid consists of row headers, column headers, and product cells — each product equals its row header multiplied by its column header.

📏 Rules

• The grid has row headers (left column) and column headers (top row)
• Each inner cell value = row header × column header
• Some headers and product cells are hidden — fill them in
• Use known values to logically deduce the missing numbers
• You can make up to 3 mistakes before the game ends
• Each puzzle has exactly one valid solution

🎮 Controls

• Click Cell: Select an empty cell to fill
• Number Pad: Click a number to enter it
• Keyboard: Type a number directly (for 2-digit, type both digits quickly)
• Delete/Backspace: Clear the selected cell
• Undo: Reverse your last move
• Hint: Reveal one correct number
• Check: Verify all your filled answers

🏆 Scoring

• Complete the puzzle as quickly as possible
• Minimize mistakes (maximum 3 allowed)
• Higher difficulties use larger grids and bigger numbers
• Use fewer hints for a better challenge
• Timer starts when you make your first move

💡 Tips

• Start by finding rows or columns with only one missing number
• If you know a product and one header, divide to find the other header
• Look for unique factorizations — some products can only come from one pair
• Use the process of elimination across rows and columns
• Headers are always unique within their row/column set
• Check your work frequently to catch errors early
