WHAT "NO ADS" ACTUALLY MEANS HERE
Plenty of apps say "ad-free" and then drop a 30-second video between every level. GridJoy doesn't. Here's the real promise — and the honest fine print:
- ✓100% ad-free — no banners, no interstitials, no rewarded video. Anywhere.
- ✓No energy bars, cooldown timers, or artificial scarcity.
- ✓All 18 puzzle types and every difficulty unlocked from day one.
- ✓No in-app purchases, no paywalls — every ghost cosmetic is earned by playing.
- ✓Puzzles generate on your device — fully offline, no sign-up.
- ✓Every hint is free — never gated behind a video.
No fine print, no asterisk: there are zero ads — no banners, no interstitials, no rewarded video, on a puzzle or anywhere else. GridJoy carries no advertising at all, funded by one developer instead of by your attention. Read the full story on the about page.
WORKS FULLY OFFLINE
Every puzzle is generated on your phone, not fetched from a server. That means no loading screens, no ads waiting to download, and no connection required — solve on a plane, on the Tube, or anywhere the signal drops. Nothing to sign up for, nothing tracking your solve.
It's the calm, offline puzzle game a phone should come with — open it and play, the way these games used to feel.
