How to play Irregular Killer Sudoku 4x4

Irregular Killer Sudoku 4x4 Rules：

Each row, column, and 2x2 block must contain each of the digits 1 to 4 exactly once.
The sum of the digits in each region must match the number in its corner.
No digit can appear more than once in a region.
- Irregular Sudoku Rule: Each row, column, and irregularly shaped block must contain all the digits (1-4) without repetition. This is the key difference.

Killer Sudoku combines the gameplay of Sudoku and Kakuro, adding to the game's complexity and fun. It not only trains players' logical thinking skills but also enhances their calculation and attention abilities.
