CHANGELOG
Every update.
GridJoy ships continuously. Here's the full history, newest first.
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.

- 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.

- 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.
