In a Royale Game, a new danger is introduced, commonly called 'Hazard Sauce'. The Hazard Sauce slowly enters on a random edge of the board consuming an entire row or column every few turns, shrinking the 'safe' zone. If the head of a Battlesnake is within the Hazard Sauce after it moves, its health points will more rapidly decline, losing 16 health each turn. Food can and will spawn both inside and outside of the Hazard Sauce. If a snake consumes a food on a hazardous square, the hazard will not affect its health on that turn, and its health will be restored to full (100). The default hazard damage is 15, which currently adds to the normal 1 health damage per turn.
