Remote Sensing Memory is an online version of memory, a card game designed for two people, available in single player mode. Image file cards are laid out in a grid face down with the earth logo on top.
Take turns flipping pairs of cards over. On each turn, the player will first turn one card over by clicking onto the earth logo, then a second by doing the same. If the two cards match, the player scores one point, the two cards stay image side turned up on the game board and the player continuous. If the images do not match, the cards are turned back over.
The objective is to match all pairs in the shortest amount of time. (One point is scored for each matched pair, and the player with the shortest amount of time needed after all the cards have been matched wins.) When cards are turned over, it is important to remember where they are located for when the matching card is turned up later in the game.
At the end of the game you click on the images to find out from which part of the earth they are. Click again on the image to collect some more information.
