Feather Logic is a Sudoku-based puzzle game with a clear and structured goal. The player is presented with a 9×9 grid that is partially filled with numbers from 1 to 9. The objective is to fill in the remaining cells so that each row, each column, and each 3×3 block contains all digits from 1 to 9 exactly once.
Feather Logic offers one consistent level of difficulty. The challenge focuses on logical accuracy and attention to detail rather than speed or variation. The player interacts directly with the grid: by selecting a cell and choosing a number, they work toward completing the sequence correctly.
The game limits the number of mistakes to three. Each incorrect number decreases one of the three available “lives,” shown by an indicator on the screen. After three mistakes, the session ends, and the grid resets for a new attempt.
There are no additional tools such as notes or hints. This ensures that all progress depends entirely on logical reasoning. Every correct input brings the player closer to completing the puzzle, while each mistake serves as feedback for improvement.
Feather Logic provides a straightforward and focused gameplay experience. Its single-difficulty mode, simple interface, and clear feedback system make it a concise implementation of Sudoku logic in a minimal environment. The purpose is to test observation, reasoning, and numerical organization without external distractions.
