What is Sudoku?
Sudoku is a popular logic-based puzzle played on a 9×9 grid divided into nine 3×3 boxes, where the goal is to fill the empty spaces with numbers from 1 to 9 so that each row, column, and box contains every number exactly once. The puzzle begins with some numbers already provided as clues, and players use logical reasoning—not guessing—to deduce where the remaining numbers go. While the classic version is the most common, there are many variations, such as Mini Sudoku, Killer Sudoku, and Samurai Sudoku, which add unique twists to the challenge.

Hashi: Bridges
Hashiwokakero (often called Bridges, Ai-Ki-Ai, or Chopsticks) is a logic puzzle where you connect numbered circles (“islands”) with straight vertical or horizontal lines (“bridges”).

Whether played online or through a mobile app, Killer Sudoku offers an engaging and intellectual way to spend your time.

This clever mix of dice rolling and grid-based logic offers both chance and strategy, making it an engaging alternative to Sudoku.
