This is a title and short description, likely for a mobile game app. It's already quite concise, so significant rewriting isn't possible without changing the meaning. However, here are a few slightly altered options to maintain the same tone and information while slightly changing the wording:
Option 1 (Focus on the prank aspect):
Ultimate Jumpscare Prank! Scare your friends with this FREE horror game! Download now and unleash the fright!
Option 2 (Focus on the scary aspect):
Jumpscare Horror Game: The ultimate scary prank! Download this FREE jumpscare game now and scare your friends!
Option 3 (More direct):
FREE Jumpscare Game! Scary pranks and horror await! Download now to scare your friends!
These options use slightly different phrasing and sentence structure but retain the core message of a free jumpscare game designed to prank friends. There are no images to maintain.
