On Solitaire Arcade the Eight names the next suit. Same-rank dumps set the pile, and queens, aces, and twos only match.
Crazy Eights Cards: What Eights, Queens, and Twos Do
On Solitaire Arcade, almost every card does the same quiet job: match the discard by suit or by rank. One rank breaks that pattern. An Eight can land on anything, and unless it empties your hand you name the suit that has to come next.
Queens, aces, and twos look like trouble if you arrived from Uno or a kitchen table that loads them with Skips and Draw Twos. Here they only match. Setup, the deal, and the full scoring list live in the How to Play Crazy Eights guide. This article stays with what happens when those cards hit the pile.
An Eight chooses the suit
Any Eight is legal on your turn. It can follow a king, a three, or another Eight. If you still have cards afterward, you name hearts, diamonds, clubs, or spades. The next player needs that suit, or an Eight of their own.
Suppose the discard is the 10 of spades and you play the 8 of diamonds, then name hearts. A heart is legal. Another Eight is legal. The 10 of clubs is not, even though tens were matching a moment ago. The named suit replaces ordinary matching until someone plays a non-eight or the hand ends.
Ending on an Eight
If the Eight is the last card in your hand, you are out. You do not name a suit, and the next player does not get a chance to answer. Your score for the hand is 0. The Eight is gone, so nobody is charged 50 points for it.
That finish is easy to miss if you are waiting for a suit picker. The picker appears only when the Eight leaves cards in your hand.
Several cards of one rank
Bicycle's published Crazy Eights plays one card on a turn. On Solitaire Arcade you may play two or more cards of the same rank, provided the first card would have been legal by itself. The last card sets what the next player must follow.
Clubs were named, and you hold the 4 of clubs and the 4 of hearts. The club has to be played first, because it is the one that answers the named suit. Play the heart second and the table now follows hearts or fours.
Eights use the same pattern. Two Eights are legal whenever one Eight would be. If cards remain after the last Eight, you name a suit once, for that last Eight. If the last Eight empties your hand, the hand ends and there is nothing to name.
Queens, aces, and twos can be dumped this way too. Three queens are a strong turn when the first queen matches. They still do not skip anyone.
Queens, aces, and twos only match
A queen matches queens or its suit. An ace matches aces or its suit, and in the score it is worth 1. A two matches twos or its suit. While a named suit is in force, those cards still have to be that suit. Direction stays clockwise. Nobody draws because a two was played.
Those effects belong to other rules. Uno prints them on dedicated cards. Some home games of Crazy Eights pin Skip, Reverse, or Draw Two onto queens, aces, or twos, and the chosen ranks are rarely the same from one kitchen to the next. Crazy Eights vs Uno is the longer translation if that is the deck you are arriving from.
What the cards are worth if they stick
Going out scores 0, whatever the last card was. Cards left in other hands are charged at the usual Bicycle values. An Eight is 50. A king, queen, jack, or ten is 10. An ace is 1. A 6 is 6.
The Eight is the card that both saves you and punishes you. Played, it can reset the suit or end the hand. Left over, it is the heaviest card in the pack. Faces and tens are the next bills. Aces and low ranks are cheap to be caught holding.
Shooting the moon in Hearts is a different kind of score swing, in a trick-taking game where taking every penalty card can flip the hand. Crazy Eights never asks for that. The swing here is simpler: who is still holding the 50-point rank when somebody goes out.
Drawing is not a card
No rank forces a draw. Draw is a choice you make on your turn, including when you already have a legal card. You take one card. It is not played for you.
You reach for Draw when you are stuck, and also when the legal card is one you would rather keep. The opponents you face will keep drawing until they can play, then play that card. Your turn does not work that way.
When the stock is empty, cards under the top discard are shuffled into a new stock and the draw continues. The top card stays, so a named suit or a matched rank does not vanish in the shuffle. If only the top card remains, that player passes, and a row of passes ends the hand on the leftover scores.
Where to spend the Eight
Naming a suit you still hold gives you a way back in. Naming a suit just to be contrary, while your own hand is full of something else, often means your next turn is a draw. Holding every Eight for a last-card finish can also leave you unable to answer the suit in front of you.
Which of those to choose depends on the counts and the pile. Crazy Eights Strategy: How to Win More Games stays on that decision. The suit picker itself is the thing to try first: play Crazy Eights and finish a hand that includes one nomination.
Other exception rules on the site
Thirteen, the other shedding game here, breaks its normal matching rule only for specific bombs against 2s. The lengths are exact. What can beat a 2 is the short version, and How to Play Thirteen is the parent ruleset if the combinations are new.
Spades is a partnership trick-taking game. Nothing in it nominates a suit mid-hand. It belongs in the same evening if you wanted a table and the discard pile has worn out.
