Smart As is free for PS Plus members tomorrow

The next free PlayStation Vita game tests how smart — or dumb — you are compared to other players around the world.

Smart As, which released in fall 2012, joins the Instant Game Collection tomorrow as a free game for PlayStation Plus members. If you subscribe to the premium service and own a Vita, it's yours to download.

The game consists of a bunch of puzzles in arithmetic, logic, language, memory, and additional categories. The point is to not only see how well you stack up against other players but also train yourself so you can improve little by little — and have the Brain Power ranking to show for it.

Currently, other Vita games in Sony's Instant Game Collection include Uncharted: Golden Abyss and Sonic & All-Stars Racing Transformed.
