Arena · the games played against other people · a directory, not a grade

Where you play against other people. Pup

Bozo, the Guillotine companion, NFL Survivor, the DFS solver and the live draft rig all put you across from a person rather than across from a number. This page is the directory to them and nothing more: it lists them, links them, and shows each one's own tier and machine surfaces read live from /data/surfaces.json. Being listed here is an address, not a verdict — the chip on each card is that surface's claim, and this page makes none of its own.

No oracle lives here. Every game linked from this page runs on dated 2026 inputs. Nothing here has established betting profitability, and a tool being live is not the same as a tool being right.

The games

One card per Arena surface in /data/surfaces.json, rendered from the file — the count is the file's, not a number typed into this page. A collar means the surface earned one; the criteria are written down in receipts-method.md. Creating and joining leagues lives on draft-leagues.html, which owns no machine surface and carries no nav, so it is a link here rather than a card.

Under construction

Only what the data already names as planned, so no card here can invent a capability. Each one is a surface that is written down and not callable. None of them has a button, a form or a link to a dead anchor: a card that says it is not built is honest, and a live-looking control that silently fails is not.

The same directory for machines

Assistants should read the map rather than scrape the cards above.

  • /data/surfaces.json — every surface with its page, tier, live machine access and planned list. The Arena rows carry domain: "arena", added 2026-08-09; this page renders exactly those and nothing else.
  • /data/league.json, /data/bozo-rules.json and /data/survivor.json — the configuration, ruleset and win probabilities behind three of the cards. Each card links its own files too.
  • dd_bozo_week, dd_bozo_standings, dd_draft_board, dd_survivor_week, dd_survivor_ev, dd_optimize_survivor_path, dd_solve_dfs_lineup and dd_league_overview — read-only Worker tools behind these games. The map is the authority on which are live; this list is a convenience.

Arena is a directory over surfaces that already exist. It owns no data file, so it has no row of its own in the map — a hub with a row would be claiming a surface that does not exist.
