OkuDoku Number Brain Challenge

OkuDoku is a combination of 2 classic games Sudoku and Tetris. We have taken all the best from two favourite games to create a truly challenging experience for puzzle lovers.You can play against yourself by beating your own high score or compete in Daily Challenges.

The game is easy to play but in order to complete Daily Challenges and get a really high score, you will need to plan your moves a few steps ahead.


How to play:
1. Drag and drop blocks with numbers on the board
2. Build lines or squares that contain numbers from 1 to 4
3. You score every time you complete a line or a square with all numbers from 1 to 4
4. Lines and squares get cleared once all the numbers from 1 to 4 are added
5. Plan your moves to combine multiple lines and squares in order to get even higher score
6. Game ends when you don’t have any available moves left


Daily Challenge:
- Every day we release a new challenge for you to play
- Challenge is started with a predefined set of numbers on the board
- The goal is reach a target score and not to run out of moves too quickly
