EYEZMAZE is a website with a small, but growing collection of games that requires only very little instructions to play.
^P.S. notice the paper-rock-scissors game in the bottom right corner?The star of the show here is the
GROW series, where basically one clicks and drags things onto a 'base' in various orders to make them grow. The key of the game is, each item you put onto the 'base', and the order in which you do so, will affect the growth of items already put there.
