iPhone
Daily Sudoku with your group — same puzzle, race the clock, see who finishes first. New leaderboard every morning.
Sudoku Crew is a clean, ad-free Sudoku app built around one idea: race the same daily puzzle as your friends and see how you stack up.
EVERY DAY, ONE PUZZLE
Everyone plays the same puzzle each day. Solve fast, solve clean — your time, mistake count, and assists used appear on your group's leaderboard.
PRIVATE FRIEND GROUPS
Create a group, share the invite code, and you're set. No public leaderboards, no strangers, no follower counts. Just your people.
PLAY WITH FRIENDS, TURN BY TURN
Multiplayer mode is turn-based async sudoku: place one digit per turn, wrong guesses end your turn. Notifications poke you when it's your go, so you can play across hours or days without staring at the screen. Send an invite link to anyone.
YOUR OWN PACE TOO
Plenty of generated puzzles across Easy, Medium, and Hard if you want to play outside the daily. Mistakes counter, pause, in-progress saves — all the standard quality-of-life stuff is in.
A TUTOR THAT ACTUALLY TEACHES
Stuck on a hard puzzle? Tap the lightbulb. The tutor walks you through how to find the next move — 21 techniques in total, from naked and hidden singles up through pointing pairs, box-line reduction, X-Wing, XY-Wing, XYZ-Wing, W-Wing, Swordfish, Skyscraper, Empty Rectangle, 2-String Kite, Finned X-Wing, Finned Swordfish, Jellyfish and more. It highlights the cells, shows the candidates, and narrates the deduction step-by-step. Learn while you play.
COACH MODE
Want to drill a specific technique? Coach Mode loads hand-built boards where one technique is the next move you need to make. Get X-Wing into your bones in a few minutes, then move on to XY-Wing.
AUTO-PENCIL ASSIST
One tap fills in the candidates for every empty cell, so you can focus on the deductions instead of bookkeeping. Optional — never forced.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• The tutor learned a new advanced technique (Unique Rectangle) and can now crack harder boards.
• Fixed a bug where the tutor would say "no more moves" after a few hints, even when more were still available.
