Velo Sudoku is a free offline sudoku game for calm, focused logic. Play at your own pace in Zen Mode with no timer, or chase your best times on five difficulty levels.

Solve a quick board with your morning coffee or take on a hard one in the evening. The board stays clean and easy to read.

What you get:
• 5 difficulty levels: Very Easy, Easy, Medium, Hard and Very Hard. Every board has exactly one solution.
• Daily, weekly and monthly puzzles: a fresh Daily puzzle every day, plus a harder Weekly puzzle and Monthly puzzle. The monthly calendar shows which days you've solved.
• Conflict highlighting: repeated digits in a row, column or block turn red, so obvious slips show up right away. "Check" finds the rest.
• Pencil notes that clean up after you: write candidates (1–9) in empty cells. When you place a number, matching notes in the same row, column and block disappear.
• Tools for when you're stuck: "Check" verifies the board and locks correct numbers, "Peek" reveals one cell, "Quick Pencil" fills notes in a row, column or block, and "Golden Pencil" fills notes on the whole board.
• Coins and achievements: earn coins for solved boards and daily streaks, spend them on tools or to save your streak, and collect dozens of badges.
• Controls your way: switch between "Cell first" and "Number first" input, reorder the toolbar with drag and drop, and pick a light or dark theme.
• Phones and tablets: a full landscape layout fits the board, keypad and challenges on big screens.
• Offline play and cloud backup: play on a plane or a train with no internet. Every move is saved automatically, and optional Google Play Games backup keeps your progress when you switch phones.
