Koozac is an action puzzle game developed by UK-based game developer, Ben Cusack. The game was nominated at the 2006 International Mobile Gaming Awards.
Koozac combines the basic
principles of two prominent casual games-Sudoku and Tetris. The concept of the game is simple: position the falling blocks on top of each other to complete the number shown at the bottom left of the game window (in other words, if you need to complete a 5, stack a #3 block with a #2 block). If you succeed to complete a number, the corresponding blocks will disappear. 25 blocks on the board end the game with the opportunity to advance to higher levels.
