lowhighfind density

Each blob is the kernel-density bloom of every successful NFC tap at a tag. Cadaval has no fixed booth sectors — players hid their own tags across the festival grounds, so the heatmap traces the paths players actually walked.

TAGS

One row per in-play tag, 57 total. Tags were hidden across Cadaval by players and organisers. Sortable and searchable, with a top-10 podium and ranked find-distribution curve framing the spread.

Find distribution ranked curve. Sorted find counts across 57 tags. Median 38, top decile accumulated 19% of all finds.

Each point on the curve is one tag, sorted by finds. The dashed reference lines call out the median (38), top-quartile, and top-decile thresholds. The top 10% of tags accumulated 19% of all finds — long-tail but not winner-take-all.

No reward boosts ran during Festival da Juventude — every find here is organic.

MERCH FAIRNESS

Did the leaderboard winners take everything? Per-SKU velocity on one side, and a rank–claims scatter on the other, triangulate the answer.

MERCH VELOCITY

Sorted by volume total units claimed by players. This is the fairest single number: an item with 200 units claimed beats one with 5, regardless of how fast the 5 went. Click any row for its claim curve.

DID THE WINNERS BUY THE MERCH?

Each dot is one player who bought ≥1 merch item. X-axis: their rank on the find leaderboard (1 = top, log scale). Y-axis: how many merch items they bought. A steep down-slope would mean leaderboard winners hoarded the merch; a flat cloud means everyone got a fair shot.

Leaderboard rank versus merch claims. Scatter of leaderboard rank against merch claims for 85 buyers.

Trend is weak — high-ranked players bought slightly more, but the bulk of merch was claimed by mid-rank players. The merch race isn't the leaderboard race.

THE VERDICT
82%of merch went to mid-rank and casual players — not the top of the leaderboard.

Merch distribution at Festival da Juventude was fair. The on-chain claim rate-limit prevented the leaderboard winners from sweeping inventory; the top-10 hunters captured only 18% of all merch claims.
