There are six Sudoku squares below, and five of them are stand alone puzzles. But, like with a good collaboration, they are also part of a single greater puzzle. The first clues as to what that is are in the titles of each puzzle and, as the solution unfolds, you will discover a relationship between the puzzles to gain additional information that is needed to complete the last square.

Don't be put off. Specific rules for each puzzle are listed below, but normal Sudoku rules apply to all of them. There is a single clear solution and when you have the puzzle all wrapped up, there is a surprise hidden within for you to enjoy.

Rules in common between several puzzles:

Digits in killer cages do not repeat, and sum to the indicated total.

Kropki/dots/Letters on edges between two cells indicate the relationship between the values in those cells:

It may not be assumed that all possible Kropki, X, or V have been given.

Digits in blue cells and arrow pills are read left-to-right or top-to-bottom.

Additional rules per puzzle:

Japanese Sum Sudoku: Numbers in blue shaded cells give the sum of contiguous shaded cells within the outlined area. Two blue cells together is a 2-digit number. Rows and columns without a clue may or may not have shaded cells.

A Plane Face

by Raumplaner

Cube construction: Identify the three 3x3 Sudoku boxes, who can be stacked on top of each other without rotation and form a 3x3x3 cube. When viewed from each side of the three directions, each of of the three layers of the cube must contain a full set of the digits 1-9. The three selected boxes must not share the same row or columns of the Sudoku grid (they must not 'see' each other).
