A '''cage''' is the basic building-block of a [[Killer]] Sudoku puzzle. It is a set of contiguous [[cell]]s, surrounded by a dotted outline or marked off with distinctive background color. The cage is marked (usually in the top left corner) with a number which represents the sum of all the cells in the cage.

The highlighted part of this grid shows a cage with 4 cells and a sum of 26.

According to the [[Killer Convention]], [[digit]]s can only appear once in a cage, even if the normal Sudoku rules would allow this.

Through application of the [[45 rule]], a solver may create additional [[cage-splitting|split cages]] or [[cage-splitting|hidden cages]] that subdivide or overlap the original given cages of a puzzle. These cages will only follow the [[Killer Convention]] if their cells [[see]] each other.
