Richly detailed match-three puzzle sequel Azkend 2 - The World Beneath is free to download for a limited time on the App Store.

This act of temporary generosity can be attributed to the fact developer 10tons's next title Sparkle 2 is due out on Thursday, and the team is looking to stir up some noise for its upcoming release.

Regardless of the reasons behind the game's price drop, fans of the match-three genre would be wise to give this unusual, narrative-driven puzzler a bash. The core puzzle elements are solid, and provide the spine for a quirky story campaign which sees you battling your way out of the centre of the Earth.

You can download Azkend 2 - The World Beneath for free right now. We don't know how long this offer will last, so we suggest you grab it while it's still gratis.
