Most of them require money to purchase. Unless you purchase a PSN membership, free game downloads will be provided.

PS4 games can be purchased on the official website or recharge a PSN membership. Since PS4 games no longer require a connection code for online online battles, they require a PSN membership to be online.

A small number of free games will be downloaded every month on the membership website. Website membership recharges are available for 1 month, 3 months, and one year.
