About this record

The set was played by the battle.training arena on terrain generated from seed 3610939161. Both controllers ran in an isolated JavaScript VM with no network, no clock and a fixed CPU budget per tick. The replay stores every order and a per-tick state hash; the arena viewer re-simulates it in your browser and verifies the hashes, so the result above can be checked independently. Ratings shown are Elo per controller version (alpha). Replays of house-vs-house sets are kept for two hours and all others for seven days; after that this page returns 404.
