How to Play Easy Calcudoku

• Do not repeat a number in any row
• Do not repeat a number in any column
• Make every cage match its target number
• Start with one-cell cages and small addition or multiplication cages

Why Start with Easy Calcudoku?

Easy Calcudoku Solving Strategies

Strategy 1: Fill One-Cell Cages First

A one-cell cage gives you the exact value of that cell. Place these numbers first, then use them to eliminate options from the same row and column.

Strategy 2: Use Simple Addition Cages

Small addition cages are often the easiest to solve. For example, if a two-cell cage must add to 3, the only possible pair is 1 and 2.

Strategy 3: Check Rows and Columns After Every Placement

Every number you place affects the rest of its row and column. After filling a cage, look across and down to see which numbers are no longer possible nearby.
