Spin-offs are nothing new. Televisual history is littered with some great examples, though there are just as many awful spin-offs available. For every Frasier, there’s a Mrs Columbo (yes, that really was a real thing). Spin-offs are also common in video gaming, again with varying results.

J.U.L.I.A. Untold HD ($0.99) is a a spin-off to the Mac and PC title, J.U.L.I.A. The title looks to expand on the sci-fi adventure universe.

Developed by CBE Software and published by Lace Mamba Global, J.U.L.I.A. Untold HD, is a challenging puzzle game, featuring 50 puzzles.

The developers call J.U.L.I.A. a “charismatic, eponymous artificial intelligence system.” J.U.L.I.A. Untold HD starts with J.U.L.I.A discovering a partially destroyed backup database. It is your mission to fix this and discover the secrets it holds.

Graphically speaking, J.U.L.I.A. Untold HD isn't stunning.

While J.U.L.I.A. Untold HD exists in the same universe as the original J.U.L.I.A. title, it can be played as a stand alone game which is ideal for me. I can’t say I have heard of J.U.L.I.A. before this point.

Gameplay is based on the principles of circuit assembling. To complete each challenge, you will need to reactivate five memory clusters, each consisting of nine regular puzzles and one “boss” puzzle.

J.U.L.I.A. Untold HD also includes six special tiles to discover, as you work your way through the game, as well as three difficulty levels.

J.U.L.I.A. Untold HD is available in the App Store now for your iPad, iPhone, or iPod Touch. At such a low price, you have little to lose by giving this game a go.

Have you played J.U.L.I.A. before? Does it leave you powerless, or make you blow your fuse?
