I have a card game called “Find It First”. Each card has 8 unique objects. And between every 2 cards there is just 1 common object. The puzzle for today is - what are the fewest number of objects you need for a pack of 9 cards. Remember, each pair of cards should have a different common object.
In the above 3 cards look closely and you’ll find sun-glasses, dolphin and dog as the common object between each pair of cards.
