Strategy

Our snake's strategy was aggresive. For each turn, if the snake wasn't the largest on the board, or if the health was below a specific threshold, the snake would navigate towards the closest food. Otherwise, it would try to target the other snakes' heads to either eliminate the opponent in a head-on collision or trap them by cutting off their path.

Tournament - Stay Home and Code

The snake beat six other competitors the second round of Group B to qualify for the Quaterfinals, where it was eliminated. There were 32 competitors in the veteran division. Our games were played on a 11x11 board with 4 food spawned at start.

Timestamp on the BattlesnakeOfficial Twitch stream is 2:16:32-2:25:35 for Group B, and 4:04:08-4:15:18 for Quaterfinals.
