Whether it’s an accident or by design, Beats Slider is free one day ahead of the Wednesday rollout for the free PlayStation Mobile app of the week. The game combines sliding puzzles with an excellent techno soundtrack, and allows you to remix songs after beating a puzzle. It usually costs 79 cents, so I doubt even if it is a mistake, Sony will bother correcting it since it’s not like a full retail game was unlocked before released accidentally like with Michael Jackson: the Experience before the Vita’s launch. Beats Slider will take up 83 MB of space, so if you’ve got very little space on your memory card, you may need to free some up before downloading it. The free PSM game promotion runs for five more weeks and will conclude on Feb. 25.
