Hexadoku

Hexadoku is a variant of the popular logic puzzle Sudoku. Instead of the standard nine 3x3 regions, Hexadoku uses a 6x6 grid divided into six 3x2 rectangular regions. The objective remains the same: to fill the grid with digits from 1 to 6 such that each row, each column, and each of the six 3x2 regions contains all of the digits from 1 to 6 exactly once.

Like traditional Sudoku, Hexadoku puzzles start with a partially filled grid, and the solver must use deductive reasoning to determine the placement of the remaining digits. The constraints are similar to Sudoku but adapted for the smaller grid size and different region shapes. The 3x2 regions are often arranged in a way that creates a visually distinct pattern within the 6x6 grid. This alteration in region shape and size is the primary difference from standard Sudoku, introducing a slightly different set of spatial relationships to consider during the solving process.

Hexadoku puzzles are generally considered easier than standard 9x9 Sudoku puzzles due to the smaller grid and fewer numbers to work with. However, they still offer a satisfying mental challenge and are a good introduction to logic puzzles for those new to the Sudoku family. The game can be found in puzzle books, online gaming platforms, and mobile applications.
