Hello how may I help you? How do we decide who's it first in the game of tag Would you like to know the rule based on playground rules or standard rules? Playground old school Playground rules dictate that the first person to ask who's 'it' is 'it'. Would you like to know more? Yeah who developed these rules? It is uncertain as to who first invented tag but the game was recorded to have been played as early as 1743 We always just said not it and the last person to say not it was it That rule follows the standard rules of gameplay rather than playground rules I also like to just say I'm it then tag the fat kid next to me and run really fast Traditionally, when there is a fat kid in play, that is the rule that is always used instead. Would you like to know more?
