Wordoku Game

Wordoku is a logic-based puzzle game developed by Code This Lab s.r.l. that puts a fresh, alphabetical twist on classic Sudoku. Instead of arranging the numbers 1 through 9, players must fill a 9x9 grid using nine distinct letters of the alphabet. The fundamental rules remain the same: each letter must appear exactly once in every row, column, and 3x3 subgrid. It is an engaging brainteaser that appeals to both traditional Sudoku fans and word game enthusiasts looking for a new mental workout.

The transition from numbers to letters introduces a surprising layer of challenge, as the human brain scans letters differently than numerical digits. To accommodate players of all skill levels, this digital edition features three adjustable difficulty settings: Easy, Medium, and Hard. Whether you are looking for a quick daily puzzle or a deep logic test, Wordoku provides a smooth and satisfying gameplay experience.

How to Play

The objective is to fill all empty cells on the grid while following the core constraints:

• Grid Structure: The board is divided into nine rows, nine columns, and nine 3x3 blocks.
• No Duplicates: Each row, column, and 3x3 block must contain the nine specific letters without any repeats.
• Logical Deduction: No guessing is required; every puzzle can be solved step-by-step by looking at the overlapping rows and columns.

Interactive Controls

• Selecting Cells: Click or tap any empty square on the grid to highlight it.
• Inputting Letters: Choose a letter from the on-screen keypad to place it in the highlighted cell.
• Erase and Edit: Use the delete tool to remove a letter, or select a new letter to overwrite an existing entry.

Useful Tips

• Scan for High-Frequency Letters: Look for letters that are already filled in multiple times across the grid. These provide the easiest clues for solving empty spaces nearby.
• Work by Subgrids: Focus on 3x3 boxes that are almost complete, as they have fewer possibilities and are easier to solve.
• Eliminate Possibilities: Cross-reference rows and columns to rule out which letters cannot fit into a specific cell.
