Futoshiki

## What is Futoshiki? Futoshiki is a popular Japanese numeric puzzle game that challenges players to fill a grid with numbers while adhering to specific rules. Similar to Sudoku, the game requires placing numbers 1-5 in each row and column without repetition. Additionally, players must respect the relational signs (inequalities) placed between certain cells, adding an extra layer of strategy. With its built-in puzzle generator offering three difficulty levels—easy, medium, and hard—Futoshiki promises a unique and exciting experience for fans of logic-based games. ## Game Features • **Built-in Puzzle Generator**: Creates puzzles with three difficulty levels (easy, medium, hard). • **Relational Signs**: Inequality signs between cells add complexity and challenge. • **Two Background Themes**: Customize your gameplay with different visual styles. • **Notes Mode**: Toggle notes on and off by tapping on a selected cell for easier problem-solving. • **Unique Solutions**: Each generated puzzle guarantees only one correct solution. ## How to Play Futoshiki? 1. **Fill the Grid**: Your goal is to place numbers 1-5 in each row and column without repetition. 2. **Respect Inequalities**: Pay attention to relational signs (e.g., ">" or "<") between cells. These signs indicate that one number must be greater or less than the number in the adjacent cell. 3. **Use Notes Mode**: Tapping on a selected cell toggles notes mode on and off, allowing you to jot down possible numbers for that cell. 4. **Solve the Puzzle**: Combine logical reasoning and attention to detail to fill the grid correctly. ## Frequently Asked Questions **What is the grid size in Futoshiki?** The game uses a 5x5 grid, making it smaller but equally challenging as Sudoku. **How do the relational signs work?** Relational signs indicate whether a number in one cell must be greater than (>) or less than (<) the number in an adjacent cell. Ignoring these signs will make the puzzle unsolvable. **Is there always a unique solution?** Yes, every puzzle generated by the game is designed to have only one unique solution.
