Helpful Guide for the
newbies :
http://mousehuntguide.blogspot.com/
An excerpt from the
guide :
You start off NOVICE and
can only hunt in Gnawnia town and the meadow. It costs 50 gold to
travel to the meadow but does not cost anything to travel to
Gnawnia town.
In Town you can access the Cheeseshoppe and the Trapsmith where you
can stock up on all types of cheese (other than Radioactive Blue
cheese), and upgrade your traps (traps require a certain point
value so as your experience level goes up, you are able to buy
better traps – click on Trapsmith to see how much each trap costs
and to see what points are required for each). If traveling to
other areas (i.e. Meadow, Harbour, Mountains, Lab or Mousoleum) you
need to stock up on cheese as you cannot purchase cheese or traps
there. In Town, you can also access the Marketplace where you can
buy and sell maps and SB+. You may catch more than one map piece or
key (which you can sell here), but you must have at least 2 of an
item to sell it (i.e. you cannot sell a map piece if you only have
one – you need it for yourself to access that area). Note: Beware
of purchasing keys/maps that you will not be able to use until you
reach a certain level.
You then move up to APPRENTICE (hold the cursor over your status
bar and it'll tell you what percentage you're at) and can hunt in
the Harbour. It cost 1000 gold to travel to the Harbour. There you
can catch more pirate, burglar and zombie mice (although you can
also get them in Town). You can also catch Black Widow mice here
that drop SuperBrie+ (SB+) and Radioactive Brie (RB). But… mice
will also steal gold, cheese and points from you if you don't catch
them.
Then you move up to JOURNEYMAN and can hunt in the Mountains. It
costs 4500 to travel to the mountains. There you need to catch the
Ninja mouse that will drop a lab map piece (bear in mind that not
every ninja has a map – this is the same for any loot dropping
mice). You also have a better chance of catching Black Widow mice
here though - I think.
After that i think
you no need guide anymore... 
Some helpful Tips
:
1) Stock up on cheese
- I cant stress this enuff. Make sure you have enough cos even if
you are not sounding horn, there will be a hunt on every hour or
so, and to run out of cheese is just... terrible
In town of Gnawia,
cheese refunds for exactly the same value as bought. So dont worry
about wasting gold. You can always refund it back
afterwards.
2) Sound the horn as
often as possible. Yes the cheese may get eaten. Yes it may go
stale. Yes it might not even attract a single mousie. But every
single horn sounded adds up to your points. And possibly gold if u
did catch a mousie.
3) Upgrade your Trap
+ Base when you can. A better trap = more mice caught.
4) Try to find
friends in different time zones within your area. Or just more
friends playing Mousehunt. Because unless you are a real
maniac at MH, you wont be sitting in front of the comp 24/7
sounding the damn tooting horn every 15 mins. Your friends can help
you sound the horn when you are asleep, away or busy doing real
work. (if you left your FB on)
5) Dont be afraid to
try different maps. Some mice may follow you around when you
travelled to a new map. Be wary of the travel cost. Do stock up on
cheese before you travel.
6) Try different
cheese to see what works for you. Some may do well with just
cheddar. Or marble. Or swiss. Or brie. Different cheese attracts
different mice in different locations. Have fun experiementing.
