GAME INSTRUCTIONS
Online planet memory matching game is a grid of flipped cards, a total of 16 cards whose contents you don't know until you select them. Click on each card in pairs to try to make matching pairs of planets. When you see which planet is hidden under the card, try to memorise it. These are the planets of the solar system. If you know which planet is which, Earth, red mercury, Saturn and its rings, Jupiter and its spots, etc., it will be much easier for you to memorise the planets of the Universe and make pairs of matching planets.
