: Xbox often hosts "Free Play Days" where members can play titles like Assassin’s Creed Mirage for free during a weekend.

: Keep an eye on the Ubisoft Store giveaway page. In the past, games like Assassin's Creed Unity and Black Flag have been given away permanently.

If you can't find a free giveaway, subscription services offer the most affordable way to access almost the entire library.

Some newer titles offer "Free Play Days" or limited-time trials that let you experience the full game for a short period.
