Each row, column, and 3×3 box must contain all nine digits without repeating a number. The starting clues cannot be changed. Use Notes to mark possible numbers, Undo or Erase to correct an entry, and Hint if you need help. Finish the whole grid correctly to see the SOLVED screen. EASY STEPS 1. Select Load & play free, then choose Easy, Medium, Hard, or Expert. 2. Tap or click an empty cell and choose a number from 1 to 9. 3. Check its row, column, and 3×3 box before placing your number. 4. Use Notes for possibilities and Hint when you get stuck. 5. Fill the entire grid correctly to complete the puzzle. CONTROLS & BUTTONS Click or tap a cell — select it. Number keys 1–9 / on-screen keypad — enter a number. Arrow keys — move your selection around the board. Notes / N — toggle candidate notes instead of final answers. Undo / Z — undo a recent cell edit. Erase / Backspace / Delete / 0 — clear the selected editable cell. Hint / H — fill the selected empty cell correctly, or another empty cell if needed. Pause / P / Escape — pause or resume; the paused grid is blurred. Next / S — switch to another animated world. New — choose a difficulty and start a fresh puzzle. Use the ZBANI Full screen button to give the board more space. YOUR GOAL & HOW TO WIN Fill all 81 cells correctly. Every row, column, and 3×3 box must contain the numbers 1–9 without repetitions. The game generates puzzles with a unique solution. Difficulty levels aim for 45 starting clues on Easy, 36 on Medium, 30 on Hard, and 25 on Expert, although the generator may keep extra clues to preserve uniqueness. A wrong answer increases the mistake counter; mistakes do not end the game. On completion, the game shows your difficulty, time, mistakes, and hints used. TIPS & STRATEGIES Start with rows, columns, or boxes that have the most numbers filled in. Look for an empty cell that has only one possible number. Turn on Notes when several numbers are possible, then remove candidates as the grid develops. Use Undo or Erase to correct an answer instead of starting the puzzle over. Try Easy while learning the rules, then move up when you feel comfortable. Change the world background without losing your current puzzle. Pause if you need a break; the game also pauses when its document becomes hidden. QUICK QUESTIONS Who made this game?
