This is a title and short description, likely for a mobile game app. It's already quite concise and doesn't need significant rewriting for paraphrase. Here are a few options, maintaining the original style and tone:

Option 1 (Slight rewording):

Jumpscare Prank Game: Scare Your Friends! Ultimate jumpscare horror prank game. Scary and thrilling! PRANK! Scare your friends!!! FREE JUMPSCARE GAME - DOWNLOAD NOW!

Option 2 (More emphasis on free):

FREE Jumpscare Horror Prank Game! Scare your friends with this terrifying jumpscare game! Horror and scary fun! DOWNLOAD NOW!

Option 3 (Slightly more descriptive):

Jumpscare Horror Prank: Scare Your Friends! The ultimate free jumpscare game. Give your friends a fright with this scary prank app. Download now!

These options maintain the use of capitalization, exclamation points, and the overall enthusiastic, slightly chaotic style of the original. They also keep the core message of a free jumpscare prank game clearly visible. There are no images to preserve, so that aspect is not relevant.
