If last week's Answer column wasn't a give-away, I'm always on the lookout for new engaging puzzle games on the App Store, and the upcoming Strata certainly qualifies. By laying down colour ribbons on different levels, you have to create a pattern based on the coloured tiles already in place. The trailer will explain all.

And how beautiful is that menu? Strata looks to be a complete puzzle package, and I look forward to trying it out upon release.
