Sudokussa

Sudokussa is a variant of the popular logic puzzle Sudoku. The core objective of Sudokussa remains the same as traditional Sudoku: to fill a 9x9 grid with digits so that each column, each row, and each of the nine 3x3 subgrids contain all of the digits from 1 to 9. The unique characteristic of Sudokussa lies in additional constraints placed upon certain cells or regions within the grid. These constraints are typically indicated by specific markings or symbols within the puzzle.

These additional rules can vary significantly, leading to a wide range of Sudokussa puzzles. For example, a common Sudokussa variant might involve "killer cages," where the sum of the digits within a outlined cage must equal a given number. Another variation could be "thermometers," where digits along a line must strictly increase from the bulb end to the tip. Other Sudokussa puzzles might incorporate inequalities between adjacent cells or require specific patterns to be formed. The introduction of these extra rules transforms the familiar Sudoku solving experience into a more complex and often challenging puzzle. Players must not only adhere to the standard Sudoku rules but also carefully interpret and apply the unique Sudokussa constraints to deduce the correct solution.
