CHANGELOG
Every update.
GridJoy ships continuously. Here's the full history, newest first.
v67 — Plain Speaking
Sep 2026- Boards draw what they mean — Killer Sudoku shows its 3×3 boxes again, Kakuro divides every clue square, and Shikaku outlines your rectangles.
- The how-to-play guides match the boards — several taught marks, walls and colours that were never there.
- Far less English in other languages — puzzle names, the Arena, your daily result and achievements now translate.
- Resuming works properly — the card that reopens an unfinished puzzle shows your progress, and starting a puzzle no longer throws away one you had going.
v66 — First Steps
Sep 2026- You see your usual time before you start — picking a puzzle now shows your typical time for that tier.
- A gentler way in — Kakuro's easiest tier starts with a few answers placed, and giving up early on an easier sudoku or kakuro offers you a few free squares.
- Reminders work from your first session — and the weekly challenge no longer cuts off its countdown.
v65 — On the Board
Aug 2026- Your times stay on the leaderboards — a bad connection at the moment you finished could lose a daily, weekly or per-type record. Those are re-sent until they land, and missing per-type records are restored for you.
- We can reply to your bug reports — in the app, once they are fixed.
- Tablet layouts scale properly again — on larger screens.
v64 — No Guessing
Aug 2026- Every puzzle can be solved by reasoning — boards where the only way forward was a guess are gone. Sudoku, calcudoku, kakuro, killer sudoku and shikaku are each checked as they are made, and so is the shared daily.
- Stuck near the end of a kakuro? — take free reveals on the way out instead of quitting. Marked honestly, so it stays off the leaderboard.
- Calcudoku's first hint reads the cage maths — instead of saying “focus here”. Killer sudoku also loads faster.
v63
Aug 2026- Every how-to-play is correct now — eleven of the eighteen taught something the game never does, including cages that did not add up.
- Your Haunt, Collections and Puzzle Stamps open before your first solve — rather than after it.
- Mazes show where you can move next — and HINT reads the route you have actually walked.
- A NEW filter finds types you have never opened — and every hint now speaks your language.
v62 — Ghost Board
Aug 2026- Your ghost stands on every leaderboard — hat, halo and colours, instead of a profile photo.
- Countdown shows you the shortest path — and lets you replay the exact same grid to beat it.
- Shared solve cards carry more of you — your aura, your scene, your mastery rank, and a star for a new best.
- A dead end in a maze no longer costs your Perfect — hints now translate, and first-run screens feel warmer.
v61
Jul 2026- Every puzzle has exactly one answer — and any correct grid you finish counts, even if it is not the one we recorded.
- Rematch a friend from a finished challenge — and your best times are now kept per difficulty.
- Your ghost tries on something you own but never wear — tap it to go straight there and equip it.
- A calm glow marks each solve — and a snowflake shows the streak freezes you are holding.
v60 — Puzzle Error Fixes
Jul 2026- Puzzle error fixes — this release has no archived note beyond its name, so nothing more is claimed for it here.
v59 — No Dead Ends
Jul 2026- A hint always moves you forward — a hint on the last cell now completes the puzzle, Countdown hints truly help, and maze hints guide you back when you're stuck. No dead ends.
- Continue picks up exactly where you left off — your Shikaku rectangles and maze paths come back, not just the timer.
- Clearer mistakes — your entries show in your accent colour, and a full board always shows precisely which cells are wrong.
- Steadier across devices and sign-out — your XP, mastery, and streaks stay protected.
v58 — Clarity
Jul 2026- Faster welcome — an optional quick tutorial, pick a difficulty, and you're in. No forced ghost-naming; name yours anytime.
- Spoken feedback with a screen reader — GridJoy now speaks check results, hints, level-ups, mastery ranks, sets, and streak milestones.
- Easy Start badges on gentle puzzles — your ghost celebrates streaks, and a chip jumps from the daily to today's speed board.
- Smoother & safer — signing in no longer risks your mastery, and shared cards now read in your language.
v57 — Ad-Free
Jul 2026- 100% ad-free, for good — no banners, no rewarded videos, no full-screen ads. Anywhere. Ever. The whole app is now yours, uninterrupted.
- Nothing tracking you — the ad SDK is gone entirely, so GridJoy no longer uses an advertising ID. Privacy by default.
- Your free daily Essence moved to Rituals — the free daily Essence top-up now lives on the Rituals screen, next to your Ghost Gift. Claim it there each day.
- Lighter, faster install with the ad code removed.
v55 — Rituals
Jul 2026- Rituals — your daily puzzles now have one calm home, with an optional day-2 nudge when the next daily is ready.
- Mastery moments & NEW badges — master a puzzle type and get a calm moment to mark it, and fresh shop unlocks now wear a "NEW" badge.
- Sharper and more consistent — one name per puzzle type everywhere, with cleaner Calcudoku, Killer Sudoku, and Hex Maze symbols.
- Your widget and shop ghosts always show their face, and puzzle tutorials are now translated.
v54 — Ad-Free Finish
Jul 2026- No ad when you finish — the full-screen ad after a puzzle is gone. Just you, the grid, and your ghost.
- One daily for everyone — every player now gets the same daily puzzle, so times and streaks really compare. Re-share yours from the results card.
- Prettier daily shares — your equipped scene now sits behind the share card.
- Fixed a rare results-screen crash, tidier back navigation, and more menus translated.
v53 — Companion
Jul 2026- Your ghost gets to know you — over your first week it warms up day by day, and on day seven gives you a Kindred Glow aura to keep.
- Share your daily result — a neat, spoiler-free grid to copy and paste to friends.
- A ghost that cheers you on — your companion now reacts warmly when you fix a mistake or reach a milestone.

v52 — Welcome

- Auras are back — add a soft coloured glow to your ghost in the Bazaar.
- Fixed a home-screen widget crash, smoother daily puzzles, and polish throughout.
v51 — Streak Milestones
Jun 2026- ✦ streak badge in the win banner — reach Day 7 or beyond and the win card shows your streak count highlighted in warm gold. A visible milestone moment right when you earn it.
- Milestone badge on Personal Bests — once your streak hits Day 7, the Personal Bests strip marks it with a ✦ so the achievement is visible between solves.
- Accurate milestone rewards — the streak milestone card on the daily hub now shows all four rewards: Day 7 (streak freeze + Dedicated hat), Day 14 (Devoted halo + second freeze), Day 30 (Relentless face), Day 100 (Immortal aura — the rarest cosmetic).
v50 — Archive Replay
Jun 2026- 7-day archive — missed a daily puzzle? Add
?date=YYYY-MM-DDto any daily URL to replay any puzzle from the last 7 days. - Archive navigation — the archive banner has ← prev-day, → next-day, and TODAY → links so you can step through the week in either direction without editing the URL.
- Today's other puzzles — a cross-links panel at the bottom of every daily page lets you jump straight to any of the other 6 daily types in one tap.
