If you press 2, a question mark will appear above your Dino's head.
Unlike the Exclamation Mark, this will ONLY appear if you actually press a key.
HistoryEditThe question mark was created in the Syriac language around the fifth century. It became widely used in Europe in the eighth century. In the middle ages, it transformed into a lowercase q above a lowercase o. It was not until the eighteenth century that the modern symbol began to be used.
Besides Dino Run, question marks are used in games such as chess and Scrabble.
