Show HN: XOR's NFL Challenge – after nearly 40 years
As a kid I loved this DOS game. But I really thought the X's and O's needed numbers. So I spent countless hours trying to navigate through the compiled code trying to do it. I've often credited my interest in programming to those nights and days, waking up with the green and red lines baked into my eyeballs. Last night it took only 3 prompts.

Version & cost evidence
Source votes: 3 votes (Nov 6, 2026 UTC; cumulative since publication) Recent records to compare: “Show HN: Makoda: reuse your Codex or Claude subscriptions as API” (Show HN, Nov 6, 2026); “Show HN: Hacker Living – HN's most recommended places” (Show HN, Nov 6, 2026). Shared themes are navigation hints; they have not been verified as the same need or independent corroboration.
Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
