This is a game that combines two different genres, one of them being block puzzles and the other one being Sudoku. So, the first thing you need to do in this game is to place the blocks on the board and then you need to try to solve the puzzle by filling the rows, columns, or boxes. If you succeed in solving the puzzle, you will get a new challenge, and you will have the option of choosing a theme or not. Each theme will give you a new challenge, and you will get a new reward when you solve it.

So, the first thing you need to do is to pick a theme and then you need to start solving the puzzles.
