Meet Doki, your guide to colorful logic puzzles and Classic Sudoku. All puzzles are free. Optional Plus and hint treats give you extra explained hints. A little logic. A little Doki. A satisfying puzzle break. Pupdoku brings together colorful region puzzles and Classic number Sudoku, with Doki the terrier as your guide. Start with a short playable introduction, settle into a puzzle, and enjoy the moment the final piece clicks. TWO WAYS TO SOLVE In Pupdoku mode, place one Doki tile in every row, column and colored region. Tiles cannot touch, even diagonally. Prefer numbers? Switch to Classic and fill each row, column and box without repeating a number. Browse different board sizes and difficulties, mark possibilities, use pencil notes in Classic, and undo a move when you want to rethink it. YOUR DAILY BRAIN BREAK Come back for the Daily brain break in Pupdoku mode: a casual puzzle with no rankings and no rush. For a competitive change of pace, try the separate online Daily challenge. It uses a shared UTC day, an eligible first attempt, no hints and a clock that keeps running through interruptions. Eligible times appear in public standings under generated player names. HINTS THAT EXPLAIN THE NEXT MOVE Need a nudge? Each casual attempt includes one free explained hint. Read the reasoning before applying the suggested move. A hint is used when its explanation is revealed; applying it is your choice. The Hint control shows what is available, and ranked or no-hints challenges stay hint-free. PLAY, SAVE AND SHARE Play casual puzzles offline without an account. Resume saved puzzles, see your streak and results, and share a spoiler-free result card. Send a friend an exact-puzzle invitation with an optional recorded-time goal or a no-hints rule. Optional email sign-in backs up supported casual progress across devices; hint balances and purchases are separate. Online challenges and cloud saving need an internet connection. MAKE IT YOUR PUZZLE BREAK Choose Light, Dark or System appearance, an optional bedtime theme schedule, region-letter labels, and separate music, puzzle-sound and celebration-sound settings. Decorative motion respects Reduce Motion. OPTIONAL PUPDOKU+ AND HINT TREATS All puzzles and progress saving are free, and this release is ad-free for everyone. Pupdoku+ offers three total explained hints per casual attempt instead of one. Restarting resets the included allowance; unused hints do not roll over. Optional paid, one-time packs contain 10 hint treats for US$0.99 or 35 for US$2.99, for play where hints are allowed. Treat balances are device-local and are not included in email cloud saves. Pupdoku+ has auto-renewable plans at US$1.99 per month or US$9.99 per year. Prices vary by storefront; the localized checkout price applies. A three-day annual free trial is offered only where available and when Apple confirms eligibility; the monthly plan has no trial. Your localized full price and billing period are shown before purchase. Payment is charged to your Apple Account on confirmation, or after an eligible trial. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in your Apple Account subscription settings. Deleting the app or a Pupdoku account does not cancel a subscription. Restore purchases is available in Pupdoku Settings; consumed treats are not guaranteed to be restored.
