Nonograms – Friends-only puzzle room with replays and leaderboards
by siraben·Feb 18, 2026·5 points·2 comments
AI Analysis
●●SolidCozySolve My ProblemShip It
Nonogram leaderboards with YouTube-style replays, but the genre is saturated.
Strengths
- •Replay scrubber with KDE-style visualization makes watching others' solves feel like watching speedruns
- •PWA + offline mode means true local-first gameplay, no forced connectivity
- •Clean execution for a friend-group tool — no bloat, no analytics tracking
Weaknesses
- •Nonogram games already exist (Simon Tatham's, Picross variants, mobile clones); no novel puzzle mechanics or algorithm
- •Audience limited to friend groups sharing an invite code — viral potential nearly zero

Post Description
Invite code: hackernews. No email required for signup.
My friend group loves playing nonograms and competing against each other, but we always send each other screenshots of the solved game grid and time after the fact.
So from the start, I knew I wanted leaderboards, replays, and shareable links. I also added PWA support so it can be added to the home screen on mobile and an offline play mode.
No ads, analytics or nonsense, just nonograms.
Some other goodies as well such as YouTube-like scrubber and KDE-based visualization in replays.

CCClub – Leaderboard for Claude Code usage among friends
Turns local Claude Code logs into privacy-preserving 30-minute token summaries and publishes only counters — no prompts, files, or project names ever leave your machine. The combo of a tiny CLI with SessionEnd hooks and a Cloudflare Worker dashboard (per-group pages, auto-refresh, opt-in global board) is a smart, low-friction approach to sharing usage data. If you care about tracking AI spending socially, this scratches that exact itch without the usual signup overhead.
