Clicking the NEW GAME button will set out the cans in the green field. In Level 1 clicking cans or green field with the left mouse button will change the spaces on each side from cans to field or field to cans but the clicked space does not change. Clicking with the right mouse button will change the spaces above and below but not the clicked space. Using this method the player clears the field to All Green in the least number of clicks. The above screen-shot shows GAME 1 in LEVEL 1 after one lot of cans have beeen cleared with one click of the mouse.
In Level 2 the object is the same but now clicking the left mouse button will change the spaces each side and above and below but not the clicked space.
Clicking the GRID button will show the spaces around the cans more clearly if needed. There are four different GAMES to play in each level with a target number of clicks to aim at for each game.
