Size of board:
Click on a square above to turn over an insect, then click another square to see if you can match the insects, if not then the next square you click will turn the unmatched insects back over and the insect you clicked will be shown, otherwise if a match occurs then these two insect images remain visible. The number of tries is shown at right above. For 20 squares you can do it in a minimum of 10 tries. Change the size of the board by clicking a radio knob to adjust for your screen resolution!
