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.
