While away the time in an ocean of blue calm playing Mac game Blue Reef Sudoku. This basic Sudoku game with grids from 4×4 all the way up to 16×16 will initiate the new player and challenge the experienced ones. There are literally thousands of games to choose from, and you can even make your own puzzle. You can take newspaper Sudoku puzzles and put it in this game.
The play is to fill out the grid with numbers and, in the higher grids, letters, without repeating the digits either across or vertically. First you choose the grid size you would like to play. For novices start with a smaller grid size and if you are an expert go for the 16×16 expert level. In each grid when you hover over a square, the possible numbers that could be in that square will appear to the right of the screen. This is different from other Sudoku games where the hints appear in the box. If you do not need the help, disable the hint button to your left. To place a number in the square, you click on the box you want to input, then click on the number at the right. Begin searching for squares where there’s only 1 possible answer. Then you must determine the other numbers logically by eliminating any duplicate numbers in the row, column and the small grid.
The other buttons on the right will show error, undo a play or solve the game one square at a time randomly. All these helps will create a comfortable and easy play. The challenge is to take it to the next level and not use the hints.
As far as the play goes, it is good, but since you are not able to put in your own possible numbers, the ability to really test your skills is less in this game. Blue Reef Sudoku is a basic game for people who are into this type of play. I give it a 3.0 for its ease of learning and play.
