You Can't Play Fortnite Unblocked; Do This Instead
So you want to play Fortnite when you're at school, huh? Otherwise you wouldn't be looking for "Fortnite unblocked". Duh.
There's a pretty big problem with what you're seeking, and that is there is no way to play the game unblocked. Why would you be able to? It's a multi-gigabyte download and install.
Playing flash or browser games unblocked is one thing because unblocking websites use VPNs to allow you to play on restricted networks, but downloading a pretty large game and installing it onto a computer is another thing entirely.
Just to clarify without a doubt: No, you can't play Fortnite unblocked at school. You can either wait until you go home and play there or install the game onto your mobile phone instead. Maybe.
Play Fortnite on Mobile Instead
Fortnite Mobile allows you to use the same account you do on other platforms, so why try to go the unblocked route?
At the time of writing, Fortnite is available on iTunes for iOS devices. Unfortunately, if you have an older device, you may be out of luck here too. The game is not supported on iPhone 5S, 6, 6 Plus, iPad Air, Mini 2, Mini 3, or iPod Touch.
If you've got a compatible device, you can download and play Fortnite on it right now.
Android users are out of luck on this front -- at least for now. Epic Games is planning on releasing it on Android devices in the coming months. It can't be too long from now, as more people do have Android devices than iOS.
Just playing on mobile is far preferable to scouring the internet trying to find that one diamond in the rough that will actually let you play this game at school. Because that's not going to happen. Just download Fortnite on your phone, or be patient and wait for the Android release.
