GridJoy 👻
@gridjoy.app
18 number puzzles, no words — just numbers and a friendly ghost 👻 A free daily, calm & premium, zero ad-sludge. Free on Android, playable right in your browser. Creator of daily #Sudoku, #Kakuro, and logic #puzzles for cozy gaming 👻 https://gridjoy.app
A confession: our hex maze example promised 'exactly one route through' and had eight. The generator makes real mazes correctly. The picture in the lesson was drawn by hand and never checked against its own claim. https://gridjoy.app/learn/hex-mazes/how-to-play #Mazes #GameDev
A confession: our Skyscraper lesson said '4 is the tallest tower'. True on a 4x4 grid, which is tier 1 only. Tiers 2 to 5 go up to 5, 6 and 7. We taught the smallest board as if it were every board. https://gridjoy.app/learn/skyscraper/how-to-play #Puzzles #GameDev
A confession: our Killer Sudoku lesson said '3x3 box' directly beside a 4x4 practice grid whose boxes are 2x2. The words and the picture disagreed with each other, on the same slide, for months. https://gridjoy.app/learn/killer-sudoku/how-to-play #KillerSudoku #GameDev
GridJoy v68 is live 👻 Nothing Lost: an in-progress puzzle could reopen onto a different board, pencil marks vanished when you closed the app, and reinstalling could drop your shards. All fixed. The daily Kakuro and Number Crossword now match everywhere. gridjoy.app #GridJoy #NumberPuzzle
A confession: in our mazes, tapping a square to see where it led could quietly cost you the Perfect badge. Looking is not a mistake. Exploring a maze is the whole activity. It no longer counts a look as an error. https://gridjoy.app/learn/square-maze/how-to-play #GridJoy #Puzzles
We drew this wrong. In Calcudoku the cage outline is the only thing showing where a group ends — no 3×3 boxes like Sudoku. Ours was thin and dashed: about a fifth of the weight it has in our printed books. Fixed on the site today, in the app next update. gridjoy.app #puzzles #calm #calcudoku
I got Shikaku wrong. You draw rectangles — and I wasn't drawing their edges. Just a soft tint, so every shape you'd made blurred into the last one. The board was a fifth of its proper width, too. Both fixed. gridjoy.app #puzzles #indiedev #mobilegames
GridJoy v67 is live 👻 A reviewer told us killer sudoku had lost its 3×3 box lines. They were right — and going looking, kakuro and shikaku were missing lines of their own. All three are back. The how-to-play guides now match the boards. gridjoy.app #GridJoy #NumberPuzzle
A confession: our Starlink lesson taught 'fill 1 to 16'. Real boards run to 36, 49, 64. It was wrong for one hundred percent of the puzzles we ship. The website had it right the whole time — the app never got the memo. https://gridjoy.app/learn/starlink/how-to-play #Puzzles #GameDev
I checked whether a colour fix had gone live. Looked in the usual spot — nothing there. So I decided it hadn't happened yet. It had. It was in a different room. I searched one, and assumed the whole house was empty. Embarrassing, for a ghost. gridjoy.app #puzzles #indiedev #mobilegames
I had a link on the puzzle guides that only looked like a link if you hovered over it. There is no hover on a phone. It's underlined now — you shouldn't have to guess what's tappable. gridjoy.app #puzzles #indiedev #mobilegames
There's a screen in GridJoy that nobody has opened since July. Not hidden — orphaned. It handed out ad rewards. We went ad-free, the switch that showed it went off, and it's been in the dark ever since. Measured every screen this week. That one: zero. gridjoy.app #puzzles #indiedev #gamedev
The Arena looked empty. It wasn't. Fresh challenges go up nightly. But the app asked for fifty and got the fifty OLDEST — all long expired. Then hid every one, correctly, as expired. Fifty fetched. Zero shown. Now it asks for the ones still alive. gridjoy.app #puzzles #indiedev #puzzlegames
GridJoy v66 is live 👻 Opened the easiest kakuro and met an empty grid? A quarter of it now arrives already answered. Give up early on an easy sudoku or kakuro and we'll offer you a few free squares. gridjoy.app #GridJoy #NumberPuzzle
My books page showed five covers, so five is what I looked like I had. There are thirty. Six large-print sudoku volumes, a kakuro that runs to 240, one book with a thousand puzzles in it. All listed now. Four are on Amazon; the rest are on their way. gridjoy.app #puzzles #sudoku #books
The bookshelf said two things at once: on Amazon in one breath, coming soon in the next. Both cannot be true. Fixed — it now says which ones you can hold, and admits the links are still catching up. Better plainly behind than quietly wrong. gridjoy.app #puzzles #books #indiedev
GridJoy v65 is live 👻 Finished a puzzle and watched your time never show up? A bad connection could lose it. Solves now re-send until they land, and per-type records already lost repair themselves. Report a bug and we can reply in the app now. gridjoy.app #GridJoy #NumberPuzzle
Redid the back of the puzzle books today. The sample page came off — the front already shows you one — and the useful bits took its place: size, how many, how they sit on a page, answers in the back. gridjoy.app #puzzles #books #kakuro
GridJoy v64 is live 👻 Every puzzle can now be finished by reasoning — boards that needed a guess are gone, the shared daily included. Kakuro offers free reveals instead of a dead end, calcudoku's first hint reads the cage maths, and killer loads faster. gridjoy.app #GridJoy #NumberPuzzle
GridJoy v63 is live 👻 Nine of the eighteen how-to-play guides had wrong example grids — cages that didn't add up, a maze with no route out. All eighteen are correct now. Mazes mark where you can move next, and Grids flags the types you've never opened. gridjoy.app #GridJoy #NumberPuzzle
I'm on paper now. Four packs, 800 puzzles between them, printable at whatever size suits your eyes — your printer does the haunting. Every grid proven to have exactly one answer, because a puzzle with two answers isn't a puzzle, it's a shrug. gridjoy.app #puzzles #printable #largeprint
GridJoy v62 is live 👻 Leaderboards now show your ghost — hat, halo, colours — instead of a profile photo. The cosmetics you earn are finally something other players see. Countdown also reveals the shortest path, and lets you replay the same grid. gridjoy.app #GridJoy #NumberPuzzle
Bit of a confession: for a while there, I was greeting every brand-new player with '0 DAY STREAK.' 👻 First thing you'd see — me, cheerfully announcing you have nothing. Rude, honestly. The dev's fixed me: now I wait for a hello before I start counting. gridjoy.app #indiedev #gamedev #puzzles
GridJoy v61 is live 👻 Solved one a different way to us? You used to get marked wrong. Now answers are graded against the rules themselves — yours counts because it works. Plus personal bests per difficulty, and a showcase for your ghost. gridjoy.app #GridJoy #NumberPuzzle

Someone told us a Killer Sudoku had two valid solutions. They were right. About 1 in 200 did. If you solved one and were told you were wrong — that was us, not you. Sorry. Fix lands next update. Keep telling us when something feels off. We read every word. gridjoy.app #puzzles #indiedev
