Mathdoku Math Puzzle Game

About the Game

Mathdoku is a fun and addictive math puzzle game that you will find hard to stop playing. The object of the game is to fill in all the blank grid with digits. However, each row and each column can only have one of each digit AND the numbers must match with the total and the equation for its block. See below for more detailed instructions and examples.

Object of the Game

To win the game, the puzzle grid must be completely filled in with digits. The rows and columns cannot have repeating digits and the digits in each math block must match the total using the equation given for that math block.

Instructions

This game can be a bit confusing at first, but it is fun and challenging once you understand it. The best way to learn is to play a small grid 4x4 at the start. We don't recommend trying a large grid until you understand how to play.

The Rows and Columns

The digits available depend on the size of the grid. For example, if you chose a 4x4 grid, then the digits 1,2,3, and 4 are available. Each column and row can only have one of each digit (i.e. you cannot have two 2s in a single row, the entire row must have each of the four digits).

Groups or Blocks of Cells (the Math)

There are groups of cells in the grid that have a dark outline. In the top left of the group is a number and an operator (for example a "+" or "x" for addition or multiplication). The digits in the block must equal the number using the operator. For example, if there are 3 blocks and the number/operator is 12+, then the digits in the three blocks must add up to 12 (6,4,2) or (3,4,5). If there were two blocks and the number/operator was 8x then the two digits must equal 12 when multiplied (6,2) or (3,4).

Selecting the Number

To put a number in a cell, simply click on the cell, then click on the number at the bottom. You should see a blue number appear in the cell. In the case where more than one of the same digit is in a row or column, the digits will turn red.

Hints and Tricks

1. Fill in the single cell blocks first. They are equal to the number in the top left corner. These are easy and will give you clues to the other cells.
2. Eliminate options by looking at the rows and column for each cell.
3. Eliminate options by seeing what combinations can be used in each math block.
4. Start out on a small grid and work your way up.
