Portal Mode is a mode of Google Snake Game in which 2 apples are on the board at any given time, and once the snake eats one of them, it's head will start coming out of the other apple. The snake is able to turn 180 when this happens, and generally may pick any direction. The game ends when apples can't spawn anymore. In this game mode, apples can't spawn within a radius of 2 blocks around the snake head after an apple is eaten, so that the player won't instantly portal into a location without being able to react. The snake also moves slower in this mode compared to Classic.
The name for portal mode was coined by speedrunner "SpaceDoge" on June 11th, 2020.
