Those who are already subscribed can play the trial for no additional cost, and if they so choose, can purchase the game allowing all of their demo progress to carry over.
EA Play is a subscription service for their digital distribution platform, but it does cost $4.99 a month. In addition the the mobile games, EA boasts a 'free' 48 hour demo for their biggest simulation hit, The Sims 4 with EA Play - formerly EA Access. Players can also build and customize a home in The Sims Mobile - but just one - as the focus is placed more on a single household of up to four playable sims and their future generations. Its sim customization is more detailed, and it shares some assets with The Sims 4 as Maxis and EA worked on both titles.
Similarly, The Sims Mobile game is also a free download that can be enjoyed at no cost, but includes in-app purchases.
