Place all 20 cards on a table with the image side facing UP. Pick up any card and turn it over. Let's say that you chose the image of the cow. Flip it over to reveal the word on the back. The back of the cow image says....GREEN. Now go find the colour green. GREAT you found it.... Flip it over to reveal the word on the back. The back of the green card says.... tree. Go look for the tree image. Continue the process until all 20 cards are removed from the table. The last card you flip over should say the word of the first image you picked up, and that is how you know you've played game correctly.
