Over the past few years, I have seen names getting changed for Sudoku puzzles. Dots Sudoku became Kropki Sudoku over some period of time. Assigned Sums Sudoku became Arrow Sudoku. Perfect Squares Sudoku first appeared in 1st round of Sudoku Grand Prix 2015. However that time only horizontal occurrences of perfect squares were marked with squares shapes between the cells. Then this Sudoku type was changed to include even vertical perfect squares and it is was named Square Numbers Sudoku Now Perfect Square Sudoku is appearing again which has same rules as Square Numbers Sudoku. Square Numbers Sudoku appeared in one of the World Sudoku Championships with the same name. However now it is appearing in 4th Round of Sudoku Grand Prix 2018 with name Perfect Square Sudoku. To me both the names looks good as both describe this Sudoku type very well. Anyway I am publishing this Perfect Squares Sudoku as part of Fun With Sudoku Series as 310th Sudoku Puzzle in this Series.

## Rules of Perfect Squares Sudoku Puzzle

Standard Sudoku Rules apply. If two horizontally or vertically adjacent cells (read from left to right and from top to bottom) form a two-digit perfect square, it is marked by a symbol S. All two-digit perfect squares are marked.
