ABOUT GRIDJOY
Built by one person who got tired of puzzle apps full of ads.
GridJoy is a number puzzle game for Android. Free. No mid-puzzle ads. 18 types. A ghost who grows with you. Here's why it exists.
WHY NUMBER PUZZLES
Number puzzles work in any language. A Sudoku is the same puzzle whether you're in Tokyo, São Paulo, or Nairobi. No words. Nothing cultural blocking the path. Pure logic — readable to anyone.
That's the first principle GridJoy is built on: a puzzle game that's genuinely universal. Not "translated into 40 languages" universal — actually wordless universal.
The second principle: depth. Not one puzzle type dressed up 18 ways — 18 genuinely different ways of thinking. Sudoku teaches row-column elimination. Kakuro teaches sum decomposition. Hitori teaches graph connectivity. Each one builds a distinct mental muscle.
THE GHOST IDEA
Most puzzle apps are anonymous. You play, you leave. There's no sense of a player — just a score counter and a leaderboard rank.
GridJoy gives every player a ghost companion. It watches your gameplay, reacts when you stall, celebrates milestones with you. As you earn Essence by solving puzzles, you spend it on cosmetics — hats, auras, halos, body tints, backgrounds. 6,000+ options. 100% cosmetic. A Diamond-tier solver with a plain ghost beats a Bronze-tier in a wizard hat every time.
Your ghost is your identity in the arena. When you challenge a friend, they see your ghost. When you top the daily leaderboard, they see your ghost. It's a companion, not branding.
THE PLEDGE
- ✓No ads during puzzles — ever.
- ✓No energy bars, cooldown timers, or artificial scarcity.
- ✓All 18 puzzle types unlocked from day one.
- ✓All difficulty tiers open from the start.
- ✓Puzzles generate on your device. Works fully offline.
- ✓Rewarded ads are optional — one tap for a hint, never forced.
- ✓Cosmetics change how your ghost looks. Nothing else.
Two non-optional placements, both kept off the puzzle: a brief interstitial may appear when you return to the hub after a long play session, and banners run on lobby screens (Home, Library, Leaderboard). Never on a puzzle. Your solve is never interrupted.
WHO MADE THIS
GridJoy is a one-person project — TextualJoker, 2025–2026. No VC money. No team. No office.
Every puzzle type is hand-designed. Every difficulty tier is calibrated by hand. The ghost mascot was drawn on a Saturday afternoon and hasn't changed since. The generator runs on your device — no server, no account required to play.
It's free because it should be. The goal was never to extract money from people who love puzzle games. The goal was to make a puzzle app worth keeping on your phone — and to prove that "free" and "respectful" aren't opposites.
