The game tasks you with rescuing members of your Viking clan who have been stranded throughout the land and are trapped in ice, and surrounded by explosives, traps, and troll bogies.
You rescue your pals over the course of 140-odd levels by chopping up glaciers and cutting through ropes, and manipulating the topsy-turvy stages to your advantage.
We loved it when it hit iOS, and said "witty, varied, challenging and gorgeous to look at, Icebreaker: A Viking Voyage is one of the finest physics-based puzzlers around".
Speaking of iOS, the iPhone and iPad version has been updated with a new chapter, set inside the belly of a rampaging sea monster, that adds 40 extra levels and an epic boss fight.
The iOS edition of Icebreaker - which is no longer published under the Rovio Stars banner, after an amicable split with the Angry Birds maker - is currently on sale for £1.49 / $1.99.
The Android version is even cheaper, and available for 69p / 99c for a limited time.
