One game of Crazy eights followed from the deal to the finish, move by move, with the reason for each choice.
Three players sit in this order: you, Ada and Bo. Bo deals five cards each and turns up 9♣ to start the pile. You play first, and play goes to the left.
Your hand: 9♥, K♣, 3♣, 8♦ and 4♠. On any turn you may play a card of the same suit or the same rank as the top card, or an eight.
You could play K♣ or 3♣ on suit, or 9♥ on rank. You play K♣ first: a king is worth 10 against you if you are caught holding it, the three only 3. Ada plays K♥, matching the rank and changing the suit to hearts. Bo plays 7♥.
You play 9♥. Ada has no heart and no nine, so she draws until she finds a card she can play: 2♠, then J♦, then 9♠, which matches the rank. She plays it, and the suit is spades. Ada's hand has grown by two.
Bo plays Q♠. You play 4♠, leaving you with 3♣ and 8♦. Ada plays 2♠.
Bo has no spade and no two, only eights, so he plays 8♣ and names hearts. You have no heart, but an eight can be played on anything, including another eight. You play 8♦ and name clubs — the suit of your last card.
Ada holds 6♣ and plays it. Bo plays J♣. It is your turn, the suit is clubs, and you play your last card, 3♣. You are out.
Naming clubs was the key moment. Naming any other suit would have meant hoping somebody else changed it back to clubs before you were forced to draw.
You score the cards left in the other hands: 50 for each eight, 10 for each court card, 1 for an ace and face value for the rest. Ada holds A♠, 4♦, J♠ and J♦: 1 + 4 + 10 + 10 = 25. Bo holds 8♠, which is 50 on its own.
You score 75 from the hand. The next hand is dealt once everyone is ready, and the first to reach the target wins.
Bo's saved eight cost him 50. Holding an eight back is right while it is your way out, but a hand can end before you get to use it.
You shed your most expensive card first, played on suit and rank before spending your eight, and used the eight to name the one suit that would win you the hand.
