Target Value
Can you hit the target?
In this game, each tile corresponds to a particular mathematical operation. When you drag them to the right hand column of the table, they act on the value in the left hand column. The object of the game is to make the final value equal to the target value.

Once you have placed a tile, it can be removed using the Undo button, or the table cells themsleves can be swapped by dragging. Press Restart to try again, or New for completely new tiles.

There are three levels of difficulty, with each increase in difficulty meaning more tiles and a greater variety of values.

Hint: the target value will always be either zero, or either the highest or lowest value possible. Try and use this knowledge to help decide the best way to place the operation tiles.
