To ensure this isn’t exploited, you have a time limit imposed once you begin the trial. The free trial (regardless of the Edition or your platform) is the full game as paying customers would experience it there is no barred content that will be inaccessible. In terms of the Java Edition, which is available exclusively to Windows, Mac, and Linux, an additional set of links are available lower down on the same page, with specific instructions on how to download and install each respective version. Via Minecraft’s official website, you can access links that will lead to the download pages for the Bedrock Edition, available on Windows, Android, PS3/4/5, and PS Vita.
For those wanting to get a taste of the endless hours of entertainment that Minecraft can provide, but are yet unwilling to pay the entry fee, there is in fact a free trial of both Bedrock and Java versions of the game.
