Crazy Eights — spelled "Crazy 8s" on half the kitchen tables that play it — has survived a century because the entire rulebook fits in one sentence while the decisions never run out. Match the top discard by suit or by rank, and when nothing in your hand fits, an 8 rescues you: it lands on anything, and after it lands you name the suit everyone else must chase.
This browser version deals a genuine heads-up match against the computer. You receive seven cards, the AI receives seven, and the remainder becomes an automated draw pile with one card flipped to seed the discards. That seven-card deal is the standard two-player setup; at a physical table with three or four players you would drop to five cards each, and the rules guide below walks through exactly that difference.
The draw rule here is the classic, uncapped one — and the game enforces it for you. Cannot play? You keep drawing until you can. There is no one-card limit and no voluntary hoarding, and when the stock runs out the game reshuffles the discard pile (all but its top card) into a fresh draw pile for you. Only when there is truly nothing left to draw does your turn pass — and if every player passes in a row, the hand is declared blocked and scored, lowest hand value winning, rather than dragged out forever.
Scoring uses the traditional point values, which is where the 8 shows its second face. Each 8 caught in a losing hand costs 50 points, face cards cost 10, and number cards count their face value. Fifty points is a steep bill for one card, so the same 8 that saves a bad turn becomes the most expensive mistake on the table if you sit on it too long.
The AI opponent comes in three difficulty levels with genuinely different error rates. On easy it fumbles roughly four decisions in ten, which makes it a friendly teacher for kids and first-timers. On hard it misplays only about two percent of the time, holds its 8s until they sting, and calls suits based on what it is actually holding rather than habit.
Everything else you might search for sits below the table: the complete rules with examples, a strategy guide covering suit control and card counting, a tour of the variations this game spawned around the world, and a head-to-head Crazy Eights vs UNO comparison for families deciding which one to teach first.
