Go is the first Square on the Monopoly board. Every player starts on this square. As the players pass Go, they collect $200 (£200 in British Version). Some "House Rules" allow giving $400 for passing Go, and sometimes up to $800 for landing DIRECTLY on Go (When normal salary is $400 and the double rule in in effect). Recent editions that use the million scale award the player $2M (the equivalent of $200). In recent editions, the red lettering has been colored black, though the famous arrow remains red.
In Monopoly Junior, players collect $2 each time they land on Go.
In Monopoly Here and Now, players collect $2 million each time they land on Go.
