Gattai 5 Samurai

My first generated arrangement of 5 overlapping Sudoku's. 15-apr-2018

Symmetrical, and only with 6 givens in the center Sudoku.

Of course all overlapping area's are clueless.

Techniques to solve this: 

Box <-> Columns,Rows

"if a column or row hold same candidates in exactly 1 box, remove candidates from that box, 

 but not on the column or row, and visa versa (pointing pairs)"
