[OBJECTIVE] Remember the image locations, then try to match the pairs in the least amount of turns. [PREVIEW TIME] • Set how long (in seconds) you wish to preview the cards before they flip over. The shorter the preview time, the harder it will be to remember the locations! [NUMBER OF PAIRS] • Choose between 8 and 18 pairs (16 or 36 cards) to match. Eighteen pairs are more challenging, but much more fun! [PLAY/PLAY AGAIN] • Press the {PLAY} or {PLAY AGAIN} button to begin playing with the highlighted options. [8 Pair Scoring] 08 turns = perfect 09 turns = excellent 10-15 turns = very good 16-20 turns = good 21+ turns...keep trying! [18 Pair Scoring] 18 turns = perfect 19-20 turns = outstanding 21-25 turns = excellent 26-30 turns = very good If playing with 8 pairs, 8 turns is a perfect score. If playing with 18 pairs, 18 turns is a perfect score. Remember that the preview time also affects how easily you remember the pair locations. Be sure to post your number of turns, preview times, and number of pairs. Good Luck!
