Fun for kids. Fun for adults too. This is great skills builder to motivate you to learn your mental math skills. Based on the ancient Chinese tile game Mahjong, this math version will help you develop your math reasoning skills.

**Instructions:**

Game play is very similar to the popular
game of Mahjong. At the start of the game, a board is shown with light
and dark tiles. Only the light tiles can be used to make a math equation
in the empty boxes below the playing board. Points are scored based on
how difficult the math equation is, and it must be correct or the system
will not accept it.

Some tiles are stacked as high as four deep, and the tiles beneath cannot
be viewed until the ones above are removed. A dark tile will turn light
when the tile directly adjacent to it is selected to go into the equation.

The trick is to keep the operation symbols where they can be chosen
as needed. The equal sign is very important to have because no equation
can be completed without it. There are also a limited number of all operation
symbols.

There are only nine spaces for tiles to be placed below the game board.
As numbers and symbols are chosen, they start on the left side in the
first box and go across to the right. Here is a sample equation:

8 X 8 / 4 - 8 = 8 (the / denotes division)

This is a correct equation because 8 multiplied by 8 equals 64, which
is divided by 4 to equal 16. When 8 is subtracted from 16, the answer
is 8.

It is important to note that the equation calculates based on order
of operations, meaning multiplication and division precede addition and
subtraction.

As all the top tiles are cleared away, wild card tiles are exposed underneath.
These are either a wild number or wild symbol to be used as the player
sees fit.

The object of the game is to clear the board of all tiles and to score
as many points as possible while doing so. Making equations that are
a full 9 tiles long on each play provides a better opportunity to complete
the game and achieve a higher score.

Another condition to be mindful of is to use as many numbers in equations
as possible. Nearing the end of the game it will be impossible to finish
without an operator and an equal sign to make an equation.

Two buttons on the left side of the nine-digit equation box are "Undo" and "New
Game." If you start an equation wish to change it, click the undo
box and the tiles will go back to where they were moved from. Selecting "New
Game" clears your score and starts another game.

On the right side of the equation box is the red "Submit" button
you click when you have completed your equation, and the "Clear" button
beneath does the same thing as the "Undo" on the left side.

The running score is shown on the top left, and the highest score achieved
on the computer is displayed in the top center.
