Thunder Buddy Sudoku is a clean, fast sudoku with a coach built in. Every hint explains the technique it used, so you get better instead of just getting unstuck, and Bolty, your lightning-bolt buddy, reacts to every move. FIVE THOUSAND GRADED PUZZLES • Easy to Master: 1,000 puzzles at each of five levels, every one graded by the techniques it needs, never by guesswork. • Notes (or fill them all at once), undo, erase and digit-first entry. • Pause any time and pick up where you left off. HINTS THAT TEACH • Stuck? A hint shows the next step and names the technique, one step at a time. • Learn: short lessons from singles to X-Wing and XY-Wing, each with a live example from a real puzzle, then practice it on a real puzzle. • After every win, a solve review: your solve curve, longest think, best minute and the hardest technique you used. A NEW PUZZLE EVERY DAY • The Daily Challenge is the same puzzle for everyone, everywhere, ramping up from Easy on Monday to Master on Sunday. • Build a streak, and catch up on any day you missed from the calendar. • See how today compares with your personal best, your usual time and your trend at every level. PLAY WITH FRIENDS • Buddy Duel: race a friend live on the identical puzzle and watch their progress. • Practice against Bolty Bot, even offline. • Send a "beat my time" challenge over Messages: no account, the puzzle travels in the link. • Game Center leaderboards for every level, the daily and the week, plus 20 trophies. MADE WITH CARE • Time Attack mode when you want a sprint. • Board themes, dark mode, large text, VoiceOver and a full iPad layout. • Free to play, with occasional ads that never interrupt a puzzle. One purchase removes them for good — in this game, or in every Buddy game at once with the Thunder Buddy Pass. • No account needed. ## Key features - Thousands of graded Sudoku puzzles - Hints that teach techniques - Daily Challenge puzzles - Multiplayer Buddy Duel mode - Offline practice against AI - Customizable themes and accessibility options ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Remove Ads | $2.99 | one-time | | Thunder Buddy Pass | $9.99 | one-time | ## Frequently asked questions about Thunder Buddy Sudoku ### What is Thunder Buddy Sudoku?

A "watch an ad" break still gives you your reward. • After an ad closes, the game picks up exactly where you were. • The "Ad" label is easier to read. Thanks for playing! If you're enjoying it, a rating helps a lot. ### 1.0.1 — 2026-09-30 Fair play for friend challenges, plus a few fixes. • Fair challenges. When you send a friend a "beat my time" challenge, you're both playing the same puzzle on the same terms: no hints, no second chances, and three lives each. Want to help a newer player along? Switch on Friendly when you send it and you each get three hints, the same three whatever you've bought. Your friend sees the rule before they start. • Live duels play the same way: same puzzle, same moment, no hints, and Fill All Notes is switched off so the race is a real race. • A solve that used hints, Show Mistakes or a second chance can now only be sent as a Friendly challenge, and it no longer counts toward your best times, the leaderboards or the speed and Flawless trophies. Friendly challenges don't count either. They're for fun. • The Daily Challenge leaderboard now lists clean solves only, and the Daily always plays with three lives, so everyone is on the same footing. Your streak still counts however you play. • Show Mistakes now follows the same rules as hints: three free in each game, then a short ad (free if you've removed ads). • VoiceOver can now reach every day on the Daily calendar, every level on the Home screen, and every trophy on the Stats tab. • Friendlier wording when a challenge arrives without a name, and a few small fixes. Thanks for playing! ### 1.0 — 2026-09-29 No release notes. ## More apps by Thunder Buddy - [Thunder Buddy Weather](https://appshunter.io/ios/app/thunder-buddy-weather/id6798351579) All apps by Thunder Buddy: https://appshunter.io/developer/6798351581 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
