Your goal is to fill all hexagons with numbers from 1 to 6. Some numbers are already filled. There are only two simple rules in the game: • There can be only unique numbers in each hexagon (1, 2, 3, 4, 5, 6). Therefore, there cannot be two identical numbers in one hexagon. • Two adjacent cells from different hexagons must have the same number. That sounds easy, right? However, passing some levels can take a lot of time and effort. We have created 3000 unique levels with varying degrees of difficulty in our application. If you are playing Hexoku for the first time, try the level “Novice”. Each difficulty level contains 500 unique levels. Where level 1 is the easiest and 500 is the most difficult. If you can easily solve the 500st level of one difficulty level, try the first level of the next level of difficulty. Good luck!
