In case the online casino does not show any steady positive growth regardless of any measures taken to revive it, the owners can make a decision to close this casino for good. In some cases the casino may be closed by the supervising authority due to the licensing violation or other reasons. Things that can happen to the player's account and player's funds depend on the gambling authority that supervised this casino. UK Gambling Commission, for example, is one of the best licensing authorities that protects players' rights, and all closed casinos licensed by it always pay the balance.
