Rewards Points will only expire if an account is "inactive" for 6 consecutive months.
An inactive account is any account in which the player has not logged in or played any games (cash or free) in 6 consecutive months (explained in section 2.15 of the Terms and Conditions). Once the account is inactive for 6 consecutive months or 180 days, the available Rewards Points balance will be forfeited.
If you wish to take an extended break from WorldWinner and want to avoid any "inactivity" fees, please contact WorldWinner Player Services to request your account be closed. Players can have their accounts reopened in the future if the account was closed per user request.
