[{"data":1,"prerenderedAt":-1},["ShallowReactive",2],{"content-seo:numberBaseball":3},{"description":4,"seo":5,"faq":8},"Number Baseball is the Korean name for Bulls and Cows, the old pencil-and-paper code-breaking game built on the same idea as the board game Mastermind. The computer picks a secret number of 3 or 4 different digits from 0 to 9 — zero can come first, so 012 or 0597 are possible — and you try to work it out in as few guesses as you can.\n\nAfter every guess you get a clue. A Strike (a \"bull\") is a correct digit in the correct position; a Ball (a \"cow\") is a correct digit in the wrong position; Out means none of your digits appear in the secret. Your guesses must use different digits too — repeats are blocked as you type. Reach 3 Strikes in 3-digit mode, or 4 in 4-digit mode, and you've cracked it.\n\nThere's no turn limit: your score is simply the number of guesses. Solve it in 4 or fewer and you're an Ace Detective; 5–7 earns Sharp Reader, 8–11 Steady Solver, and 12 or more counts as Warming Up. The 3-digit mode has 720 possible secrets and the 4-digit mode 5,040. For 4 digits, an optimal strategy always finishes within seven guesses and averages about 5.2, so landing in the 5–7 range is genuinely strong play.\n\nTip: spend your first guesses finding out which digits are in the number at all, then shuffle positions to turn Balls into Strikes. Tap the on-screen keypad or type on your keyboard (number keys, Backspace, Enter). It's free, runs in your browser, and needs no sign-up.",{"ogTitle":6,"ogDescription":7},"Bulls and Cows Online | Number Baseball logic puzzle - Giggleus","⚾ Guess the computer's secret 3- or 4-digit number from Strike (bull) and Ball (cow) clues.
