The aim of grid is to end up with a picture that matches the current goal. A move is made by clicking on the square in the grid that you wish to toggle the colour of. For example, a black square when selected will turn white.
A player cannot make consecutive moves, so you must wait for someone else to make a move before you can make another.
When it is decided that the goal has been reached, a new goal will be started. A history of the moves for each goal, including the current one, can be viewed by choosing one from the select box provided.
