What are the corner spaces on the Monopoly board?

The corner spaces on a Monopoly board are the four spaces located at each corner: "Go," "Jail," "Free Parking," and "Go to Jail." Players collect $200 when they pass "Go," land in "Jail" when they draw certain cards or roll doubles three times, can rest without penalty on "Free Parking," and must go directly to "Jail" when they land on "Go to Jail." These spaces play key roles in the game's mechanics and strategy.
