Ringsum

Ringsum is a relaxing number puzzle. Circle the numbers so every row, column and colored region adds up to its clue. Every puzzle has exactly one solution, and there is no timer unless you want one.

HOW IT WORKS
Each row and column has a total. Colored regions have their own small totals. Circle the right numbers to make everything match, then erase the rest. A wrong circle costs a heart, so think before you tap.
