&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;'''Clueless''' is one of the [[Gattai]] [[Sudoku Variant]]s that combines multiple [[Sudoku]]s into a single puzzle.&lt;br /&gt;
&lt;br /&gt;
A Clueless has 9 constituent Sudokus, in a 3x3 formation. The center [[box]] of each constituent Sudoku has no [[given]] digits. Together, these center boxes form a 10th Sudoku, without any given digits. This central Sudoku is essential in solving the puzzle, as it can pass eliminations from one constituent Sudoku to another.&lt;br /&gt;
&lt;br /&gt;
Here is an example:&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The center boxes have a blue color.&lt;br /&gt;
&lt;br /&gt;
The following code string can be copied and pasted into various sudoku software programs that are capable of handling Clueless puzzles:&lt;br /&gt;
&lt;br /&gt;
