The Challenge Mesh
Every free playable in this set feeds one public board. Enter your composite score and the mesh finds exactly where you'd slot — your rank from top to bottom, your percentile, the single player just ahead to chase, and how many you already beat. The moat is what it refuses to hide: instead of a generic "explore more" nudge, it draws the land-and-expand funnel in the open — you're placing against everyone, and rank travels with you across every tool, not just this one. Runs entirely in your browser (0 uploads, works offline).
How to use it
- Type your composite score, or drag the slider — or load a preset: Rookie, Mid-pack, Contender, or Champion.
- Watch your rank and percentile update live as your row slides into the seeded board.
- Read the who's-ahead line to see the exact handle just above you — the one to catch next.
- Open the X-ray panel to see the funnel the board makes visible, then copy or share where you landed.
What this clears up (the fundamentals)
- Rank is a position, not a score — your number only means something relative to everyone else's. The mesh turns a raw score into a 1-of-N placement, which is the only figure that actually ranks you.
- Percentile answers "where do I stand?" — top 5% and top 60% can be one or two points apart when the board is dense. Seeing the neighbors makes the gap concrete.
- One identity, many playables — a composite score aggregates activity across the whole set, so the way up is breadth (play the ones you haven't) as much as depth (grind one).
- The nearest rival is the next action — "climb the leaderboard" is a mood; "beat the player 40 points above you" is a target. Naming the neighbor turns ambition into a move.
Where it's used
A FREE, top-of-funnel and retention surface — the persistent board every playable feeds, and the honest pre-signup preview of the full eval-gated leaderboard. It's a miatz build-lab concept playable: play the placement here, then learn to build the composite-scoring feed and the leaderboard yourself.
FAQ
How is my rank worked out?
Your score is compared against a seeded public board of anonymized handles. Everyone with a strictly higher score sits above you; your rank is that count plus one. Percentile is round((1 - (rank - 1) / total) × 100, 1) — a deterministic rule, no model call and no randomness.
What's the difference between rank and percentile?
Rank is your exact place — "9th of 13." Percentile is how high that place sits on a 0–100 scale — "top 31%." Rank is precise; percentile is comparable across boards of different sizes.
Why does the board show anonymized handles?
Because the point is placement, not identity. The seeded handles (like byte-badger or echo-nine) stand in for real players so you can see the neighbors above and below without anyone's data being exposed.
Is anything uploaded?
No. Your score is placed against a board baked into the page, entirely in your browser — nothing is transmitted, stored, or logged. Turn off your Wi-Fi and it still works.
Limits
A teaching placement over a fixed, seeded board of twelve handles — it shows how ranking and percentile work, not your standing on any live leaderboard. Ties place you just ahead of the matching score, and the real product board updates on a schedule from actual play. The mechanism it teaches (composite scoring, cross-playable identity, an honest funnel) is exactly the real practice.
