Can you reach Tetroku? Strategically place falling blocks in this pulse racing Sudoku/Tetris hybrid game. Complete the grid of 81 squares to reach your goal - Tetroku! Position the numbered blocks (1-9) as they fall so that the numbers do not appear in the same row, column or box. Bonus points can be gained by completing a row, column, box or slice. These are known as tricks and multiple tricks increase your bonus score exponentially. Special blocks include: - Wild block. These bocks can make things easier as they can be placed anywhere. - Random block. These blocks reveal a random number and may or may not be helpful. A special mention needs to be made of the slice bonus. This will cause wild blocks to change to number blocks- very handy.
