The matching game can be reached by selecting “Play” from the main page. Select the number of pairs you would like to match: 5, 8, or 10. Next, choose two categories you would like to match: Element Name (ie: Hydrogen), Atomic Symbol (H), and Atomic Number (1). Finally, set the timer for 30, 60, 90, or 120 seconds. With these options set, just hit “Play” and start matching!
Match pairs by selecting a card from each column. If the match is correct, the two cards will disappear. If the match is incorrect, the cards will blink red then become unselected. Clear all the cards within the time limit and receive a final score. For each correct pair selected, the player gets 100 points. For each incorrect pair, the player loses 50 points. After each round, the settings for the cards can be changed.
