Conceptis returns once again with another installment of their Conceptis Light series. This time, they've combined a logic puzzle you love with the school subject you've always dreaded. Aside from gym class. Actually, they should really find some way to blend gym class with Slitherlink... How cool would that be? Get on that, Conceptis. Anyway, today we introduce to you CalcuDoku Light, a perfect marriage between sudoku and mathematics, and similar in concept to the previously reviewed KenKen.

As with traditional sudoku puzzles, your goal is to fill the grid with digits so that no number appears more than once in a row or column. However, unlike sudoku, there are no 3x3 cages that require the unique digit rule, but you're given mathematical hints to numbers that go in smaller cages. For example, if the clue in a cage of three boxes reads "12+", you know that the three digits in that cage must add up to 12. You might use a combination of 1-5-6, 3-4-5, or 2-4-6. Similarly, "12x" means that the product of the numbers in the cage will be 12. Cages with division and subtraction clues will always contain two boxes, with the quotient or difference shown as the hint. (If no symbol is attached to the hints in the cages, look above the grid on the right side to see the operation that applies to all of the cages in the puzzle.)

Throwing down the digits is as simple as clicking on a box, then clicking the number you'd like to place there. If you want to pencil in possible numbers before you run with a more definite decision, you can click the smaller square in the lower-left corner of each box. When you mouse over a cage, the possible solutions are displayed below the grid, giving you a sneak peak of all of your options. Fill in the entire grid, and you're golden!

Thirty puzzles await you, ranging in size from 4x4 to 6x6. They might not be terribly hard for someone familiar with these puzzles, but this selection of puzzles is perfect for newcomers to this hybrid puzzle. It only takes a little bit of number sense to play, but you might find CalcuDoku hard to put down.
