A car drove into Pier View Amusements arcade in Beach Street this morning, causing extensive damage.
The police were called to the scene just before 1.30am to reports of the incident.
The manager, Rob Grinstead, said he was first informed by his niece, who lives nearby.
Mr Grinstead said: "My niece heard it - there was a bang.
"When she saw the damage she phoned me up."
CCTV was in operation, but Mr Grinstead said the lights of the vehicle were too bright - and couldn't make out the registration.
Around two hours were spent this morning making some vital repairs in order to keep the arcade open.
He continued: "We are still open. We have boarded it up for now."
Mr Grinstead has appealed for anyone with information to come forward in confidence.
A Kent Police spokesman said: "The wall of an amusement arcade sustained damage but the vehicle failed to stop following the incident.
"Inquiries are ongoing at this stage but anyone with information about the collision should contact Kent Police on 101."
