Click the Play or Play Advanced Version button on the titles screen to start. You will then be shown a blank map with South America shown in orange. In Play mode, the borders of each country are shown. In the advanced mode the country borders are not shown and you win more points for every correct answer.
On the left of the map each country is placed as a jigsaw piece. Using the mouse, left click on a country and drag it to where you think it should go on the orange part of the map, then release the left mouse button. Above each jigsaw piece is shown the name of that country, its flag and the name of its capital city. If you have placed the country correctly, to within a few pixels, the jigsaw piece will snap into place and you will hear a bleep. You will also receive 100 points added to your score. If you are not correct in placing the country jigsaw piece, then when you release the left mouse button, the country will return to the left side and you will lose some points. You can then try again. If you decide you want to try to place a country after you have added some others, you can click the Pass button without losing any points. This is particularly useful for tricky, very small country jigsaw pieces. At the end of the game you have the option to play again or claim your certificate by clicking one of two buttons that will appear.
