Thunder Buddy Sudoku

Logic Puzzles, Daily Challenge

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

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.
