Why it was withdrawn

Withdrawn on 2026-09-20 with the move to tetris-bench@3: v2 credited T-spins on hard drops, exposed duplicate candidates, ended an IQ game on a single timeout, only asked slow brains every other Blitz tick, capped Blitz at 100 ms so every hosted model scored zero, and its prompt steered every LLM to the deepest drop. The v2 recording files were removed from the site and remain in git history at commit 9bc56f8 (v1 at ffb8afd).

Why it was withdrawn

Unequal adapter information, first-option Jev behaviour, network-sensitive blended score and order-dependent rating. Superseded by tetris-bench@2.

Recordings

The v1 and v2 recording files were removed from the site when v3 was published, so these games no longer have replay pages. They remain in the repository's git history at commits ffb8afd (v1) and 9bc56f8 (v2), under public/tetris-bench/runs/.
