Hexakai

Hexakai, a Sudoku-inspired game of Hexagons, is played on a hexagonal diamond-shaped grid of cells. Instead of a single column, we have two distinct diagonals, leading to highly interesting strategies and gameplay. Boards range over a variety of sizes and difficulties and advanced options can be used to generate more unique experiences.

The game features daily puzzles that range over seven board sizes and four difficulty levels. A new puzzle is published every day!

The game is free on hexakai.com and is also available as Android and iOS apps.
