It seems to me that Ocean king arcade table or seminar tables are a money making cabinet for most arcade place here in the Philippines. I can see a lot of people playing it for hours and in some arcade they a snack bar ready for players of the said machine so they don’t need to leave the arcade just to eat or get a snack.
In some places these machine is an income generating activity to some players, hence, they are playing from the time the arcade place opened until it closes. You can see them with bags filled of tokens or sometimes they have a trolley with them.
