Your Goal:

Each shape represents a number (1-9). Use logic and the row/column sums to figure out which shape equals which number!

The Puzzle:

• Each row's sum is shown on the right
• Each column's sum is shown at the bottom
• One shape or one sum is hidden - that's your mystery to solve!

The game is paused.

The notepad helps you track possible values for each shape:

• Click numbers to cycle through three states:
• Gray - Unsure
• Green - Possible
• Red - Not possible
• Lock a value: When a shape has exactly one green value, click the lock icon to confirm it. This will:
• Mark all other values for that shape as red
• Display the locked value on all instances of that shape in the grid
• Mark that value as red for all other shapes
• Unlock: Click the lock again to reset that row
• Reset Notepad: Clear all notes and locks at once
