The game board shows shelves with pairs of item. One of each pair is eco-friendly (and has a green dot), the other isn't (and has a red dot). The items are also depicted on tiles, and there are 15 additional garbage tiles. The item tiles are placed face-down around the game board. The active player flips open a tile. If the depicted item is covered by a garbage tile on the board, the turn ends - but if it is a tile with a red dot, another item in the shelves has to be covered. If the item is still free, another tile can be flipped open. If the two tiles form a pair, the green-dotted card is put on a shelf , the red one is discarded. Also, a garbage tile can be removed from the board. If the two tiles don't match, the player has to cover all red-dotted items s/he just flipped open with garbage tiles. When all items with green dots are covered with item tiles, the game ends. If there are still garbage cards on the shelves, all players lose. If not, everyone wins. (User summary by HilkMAN)
