The Discord store has 70-plus indie titles, including everything from Hollow Knight, Dead Cells, Ticket to Ride, to RollerCoaster Tycoon 2. The store also has games exclusive to Discord, called First on Discord games. First on Discord games are only available on PC through Discord for 90 days -- although they may launch on console during that time.

Over 60 of the games are available for free if you have Discord Nitro, which is Discord's premium subscription service that costs $10 a month.
