Angry Birds Seasons, our favourite in the series of arcade puzzlers, just got itself a major update, with a whole new set of levels, set in 'South Hamerica' - think rope bridges, gold treasure, swinging gongs, rolling boulders, Aztec imagery, Peruvian pipe music, and much more. The gameplay's as tricky as always and it's terrific value for only 79p (in the UK), though do note the in-app purchases if you need extra power-up help....

Last covered here, with the introduction of the Arctic Eggspedition (sic!), we now have, from the Store description:

Angry Birds Seasons takes the captivating gameplay of the original to a whole new level! From Halloween to Chinese New Year, the birds are celebrating different festive seasons around the world! With more than 300 levels and regular free updates, these special episodes offer more challenging levels of pig-popping action and golden eggs to discover.

What's new in this version: 
SOUTH HAMERICA EPISODE! 24 free levels plus three bonus ones, each packed with relics, artifacts and… pesky piggies!

NEW PIG DAYS! Pig Days levels celebrate various special events, anniversaries and holidays from around the world – there’s a fun, new challenge almost every week!

One thing I love about the Seasons variant of the franchise is that you can start playing on any season, any year, rather than have to work your way through level packs in a strict order. Definitely better for the more occasional gamer, I feel. Here are some screens from the new South Hamerica pack:

Instant theming and great South American music in the latest update.....

And there's the new 2014 level pack, plus some bonus levels, plus some 'Pig Days' special levels, themed after historic events (e.g. the Apollo moon landing), plenty to explore!

Great atmosphere... and you just know what's going to happen to that flimsy rope bridge!

Key to this level is to dislodge that big boulder at the top - how the heck did the Incas get it up there in the first place(?!)

In addition to the small purchase price, there are freemium elements - you get 20 free power-ups anyway, plus rewards if you play each day, but otherwise....

...you'd need to buy them in the usual way. £22 is still too high, Rovio, though, for inadvertent gamer taps. Again, I'd really like to see game IAPs capped at, say, £10.

Brilliant level design and animation, and unbelievable value now, especially if you steer clear of the power-ups and Mighty Eagle - and you really don't need these to clear all levels (if you're good enough - and surely the fun of the title is in the sheer challenge?), so consider them 'paid cheats', etc.
