Futoshiki is a puzzle game that presents a grid filled with numbers and constraints. Players must use deduction and logic to fill in the missing numbers, following certain rules such as the sum of adjacent numbers in each row and column without repeating any number.
The goal is to solve the puzzle by making logical connections between the numbers and constraints. As players progress through the game, the grid becomes increasingly complex, requiring more skill and concentration to complete. Futoshiki can be played in the browser, requiring no download or registration.
