This puzzle was made to imitate the style of Scojo for a setting challenge on his Twitch stream.


Normal Sudoku rules apply.

CIPHER - Each letter represents a different digit.

COPYCAT - Place 9 Copycat Cells into the grid so that there is exactly one Copycat Cell in each row, column, and 3x3 box. Each Copycat Cell must contain a different digit. The value of a Copycat Cell is the digit in the cell rotationally opposite itself in the grid. For example, if r2c3 is a Copycat Cell, its value is the digit in r8c7.

KILLER - The values of cells in a cage must sum to the total in the top left corner.

LITTLE KILLER - A clue outside the grid gives the sum of the values along the indicated diagonal.
