CHANGELOG

Every update.

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

v49 — Arena & Web Play

Jun 2026

Arena notifications — the app now pings you when a rival beats your daily time in the Arena. Tap to see who took your rank and beat it back.
Invite a friend — Settings now has a Share Invite button. One tap generates a personalised link to gridjoy.app. When your friend installs via that link, their install is attributed to you (full in-app referral rewards coming soon).
4 more web dailies — Calcudoku, Hitori, Binary Puzzle (Takuzu), and Sumplete are now free to play in any browser, same as the Sudoku and Kakuro dailies already live at gridjoy.app/daily.
Yesterday's solutions — missed a puzzle? gridjoy.app/yesterdays-solutions shows the fully-solved grids for all 7 daily types, updated every day.
Ghost customizer — gridjoy.app/ghost-customizer now has a Shuffle button (one tap, fully random ghost across all 160 hats, 88 faces, 115 halos, and 34 tints) and separate body + halo colour picks.

Jun 2026

Saved Looks — dress your ghost, save the full outfit as a named Look, and switch between your favourites in a single tap. Looks sync across your devices via Firestore.
Living ghost — your companion now drifts through idle moods and small animations while you play. The ghost feels more like a companion and less like a static icon.
Win card sharing — beat a friend's challenge and share a clean victory card with your time.
6 languages — the app now detects your device language and runs in English, German, Spanish, French, Japanese, or Portuguese. English fallback for all other languages.
Stability and performance improvements throughout.

Jun 2026

Seasonal Haunt scenes — complete the Haunt event to unlock a backdrop, then set it behind your ghost in the Haunt diorama.
Shards renamed to Essence — a cleaner name for the currency you earn by solving puzzles. Your balance carries over untouched.
Fixed blank cosmetic thumbnails in the Bazaar — every hat, face, and halo previews correctly.
Stability and performance improvements throughout.
