Yggdrasil is a 
				board game that has gained a cult following for its interesting 
				inspiration (Norse mythology) and being one of the few 
				cooperative board games out there. (Cooperative board games, 
				for the uninitiated is where all players work together for a 
				mutual goal and either all win or lose).  Interestingly enough, 
				Yggdrasil the board game and the iPad game are released by 
				Ludonaute, a young french outfit.  This allows a faithful 
				conversion to the iPad but does pose certain problems as can be 
				seen later.
		
				As mentioned before, Yggdrasil takes its name and inspiration 
				from Norse Mythology where the great Ash tree Yggdrasil harbours 
				the different worlds of existence.  The evil enemies (Nidhogg, 
				Surt, Heimdall, Fenrir, Jormungand, Loki) are advancing on 
				Odin’s House and you take control of six gods as you try to 
				fight them off.  If the enemies reach Odin’s House (or a certain 
				number make it past some points along the way), they will bring 
				on Ragnarok and the end of the world.  As each enemy advances, 
				you use the active god to perform three actions in different 
				worlds. You can get the Valkyrie to reap viking souls from the 
				islands underneath that you can then use during your die roll 
				against the enemies.   You can get the Elves to forge a weapon 
				which can be added onto die rolls.  You can try to defeat an 
				enemy and make it move a step backwards.  There are nine actions 
				in total and can be generally categorised as gathering items to 
				affect die rolls, defeating enemies, trading amongst the gods or 
				the preparation of these actions. 
				
				Each enemy will bring with them their own special actions as 
				they move forward.  Fenrir needs to be calmed before any other 
				actions can be taken, wasting your precious turns for each 
				unsuccessful attempt.  Nidhogg advances the furthest-behind 
				enemy along.  Loki enlists the power of the Giants and each 
				Giant has its own debilitating powers that need to be defeated. 
				 The enemies do get stronger as they advance so it is 
				advantageous to try to stop enemies advancing too far along as 
				they become too powerful.
		
				As far as board game conversions go, Yggdrasil is eye-catching 
				and matches the board game perfectly,  a testament to the care 
				that Ludonaute have put into making an accurate reproduction. 
				  The game though looks great and follows the art of the board 
				game closely.   Yggdrasil runs through the centre of the screen, 
				its branches holding up the world of the elves and Odin’s House, 
				the islands running around its trunk and the worlds of fire and 
				the dead tangled around its roots.  The screen perfectly matches 
				the beautifully painted board.  A lot of the statuses are 
				represented by symbols (for instance, each of the 
				Gods’/Enemies’/Giants’ special powers are represented by tiny 
				symbols as well as each of the actions).  For a beginner to the 
				game, it serves as a very concise but terse display.
				
				Each world has a hotspot onscreen that requires several taps to 
				accomplish an action.  I just feel that a lot of the iPad’s 
				intuitiveness is diminished as many opportunities for dragging 
				as well as saving on the number of taps is lost - the fluidity 
				of the game would have been much improved if not for the slight 
				awkwardness of the controls.
		
				In terms of difficulty, Yggdrasil throws you into the thick of 
				it.  The initial instructions are not particularly helpful as 
				they talk about bags, cards and tokens - it does seem that they 
				are  based entirely on the instruction booklet for the board 
				game and possibly even a scan.  The instructions are just not 
				intuitive, clear nor flowing.  Luckily there is a tutorial, but 
				many users will need to resort to the internet to get a clearer 
				picture on how the game is played.  The game is difficult to 
				master, as it does require constant population control of the 
				islands, careful use of each of the Gods and their special 
				powers and overcoming the different enemies/giants as they pop 
				up. I thought the game was pretty difficult to master but still 
				very entertaining.  You do get the feeling, as Ragnarok 
				approaches, as the enemies get stronger and as the Giants come 
				out that it is the end of the world, with the weight of the 
				world against you, it gets more and more difficult to find the 
				best action to take.
				
				Difficulty can be increased by adding more enemy cards to the 
				pile and you can also unlock different Gods (equivalent to an 
				expansion pack in the board game) after a few wins.  Due to the 
				steep learning curve, Yggdrasil will not be to everyone’s taste 
				and does require a lot of patience.  It does reward though with 
				one of the better hard-to-master thinking-man’s board games out 
				there.  Although for the impatient amongst you, it will punish.
