I found this example on a blog. The author says classical sudoku with some grids overlapping. How can I find out which one are overlapping. Can someone give me a starting point.

There are 4 overlapping grids.
Every 3 rows a new grid is starting.
Rating: Easy, one layer of at least one locked singles.
