The new Sussex Super League may need two divisions to cater for extra teams.
It is scheduled to start in October on Thursday evenings with a prize kitty of £1,000, sponsored by the Brighton company Ocean International Communications.
Problems will arise if more than eight teams enter.
Teams of two will be required to pay about £70 up front, plus £2 an evening at the home of the Hollingbury Club at Bevendean Primary School.
Organiser Carol Beames said: "When we know how many teams are in we can make decisions on any extras.
"Should there be ten teams then we could keep to Thursday evenings. If we have more than ten then a second division is a strong possibility."
