Nibbit: Code Daily
Puzzle
Free · Designed for iPad. Not verified for macOS.
Three code questions a day: fill the blank, predict the output, then hunt the bug — you get three looks at it. Two minutes, then you're done until tomorrow.
Nibbit is one tiny coding drop a day. Three focused questions, about two minutes total — then you're done until tomorrow.
Every day you get the same three kinds of question, in the same order:
• Fill the blank — pick the missing piece of code.
• Predict the output — say what the snippet prints when it runs.
• Find the bug — tap the line that's wrong.
It's coding practice that fits in a coffee break. Answer, find out immediately whether you were right and why, and keep your streak alive by coming back tomorrow. Think Wordle, but the puzzle is "does this Python do what you think it does?"
WHY NIBBIT
• Two minutes, not two hours. Small daily reps beat weekend cramming.
• Instant, honest feedback. Every answer comes with the reason, so you actually learn.
• One attempt a day. Today locks when you finish — no grinding, no doom-scrolling.
• Real Python, and what it costs. Data structures, algorithms and runtime — the instincts interviews and code review both lean on.
• Pick your level. Foundations, Core, or Advanced.
• Keep a streak, earn XP, climb the leaderboard against friends and the world.
NO ACCOUNT REQUIRED
Play as a guest from the first second. No sign-up, no email, no ads.
Nibbit is for anyone keeping their coding judgment sharp — students, junior devs, and working engineers who want a daily rep without opening a whole IDE.
