NumCue
Daily Code
Crack today's 4-digit code.
NumCue is a free daily number puzzle. Every day hides a new 4-digit code — every digit is unique and the code never starts with 0. Crack it in 8 tries or fewer using a classic code-breaking format: after each guess, every digit is marked green if it's the right digit in the right spot, orange if it's in the code but in the wrong spot, and dark gray if it isn't in the code at all.
Use the on-screen keypad or your keyboard's number keys to enter a guess, then press Enter or Go to submit. A digit you've already used in your current guess is disabled automatically, so you can't accidentally repeat one.
Crack today's code to keep your streak going, and share your result afterward as a spoiler-free grid — no digits revealed, just how close each guess was. NumCue is completely free, with no sign-up required.
