The game starts with some shopping on the so-called Marketplace. As an alternative you may wish to suggest NAPs (Non-aggression pacts) to your fellow Players during this Phase. In this case enter "N+" or "N-" to increase/decrease NAP Levels followed by the Player# it shall concern. Read about the effects below. The second alternative to do shopping on the market is to place an order to set the maximum level of feeding your people will get during Phase V. To do this write down a "FL" order followed by two digits that state the feeding percentage you want to give as a maximum (if you have enough crop anyway of course). The minimum number for feeding needs to be 35% to avoid workers going on strike - if you put a number below 35% the manager will correct that value to 35%.
Now back to the marketplace : every player can submit up to 5 items on the Marketplace at the end of each Turn (PHASE #12). Therefore there are 5 x 10 = 50 slots in the Marketplace. You can buy up to 99 units of an item and pay up to 999 gold coins per piece.
In this first phase you must decide on 
a> the number of units you wish to buy out of a given slot (01 - 99)
b> the slot number you want to buy from (01 - 50)
You are not allowed to buy from your own slots. The way that the items you buy are treated is like this :
>> Wood and Corn are directly added to your stock
>> Diamonds are put in the "Diamond Bag"
>> Potions, Items and Spells find their way into the SPP (Spell & Potion Pocket).
While the stock for Wood, Corn and the Diamond Bag offer unlimited capacity, the SPP has only 10 slots you can fill. Should you not have enough space to store the bought items you will lose the surplus (but still buy all items you have ordered !) - so be careful. At the end of this exchange you will see all your possessions listed again. There will also be a Stock Limit Check done : your stocked Wood, Corn, Gold and Diamonds are not allowed to surpass the given Stock Limit. You start with a capacity of 1000 units, every Province you gain with a city in it will increase this capacity by 500 more units. While Corn, Wood and Gold only count for 1 unit each, a Diamond takes the space of 3 valuable units so trade in time or make some nice spells.

Should you have any Magicians, now is the time to use their powers. Every Magician is able to use ONE Item from your SPP every Turn up to a maximum of 3 possible orders. Every Player has a Magic resistance (see Phase Vd), serving as "shield" against spells. As long as he has some Points for resistance, every spell used against him will fizzle. You can use POTIONS and SPELLS - while Potions summon a Creature that will help your troops, Spells are divided into 3 categories :
a> COMMON SPELLS : For them, your TOTAL SPELL POWER is calculated, telling how effective your spell will deliver. It depends on the following things :
     * your Effectiveness (over/under 85%) will bring/take Points
     * your Tech Level will be multiplied by 3 (up to 54)
     * The number of Magicians you have will be multiplied by 5 (up to 25)
     * If the Terrain you cast the Spell upon is a Desert, a Tundra or a simple Plain you will get 5 more Points for the favorable Terrain
     * Weather will give you from 1 to 10 more Points
So if you collect i.e. 45 points you can cast all minor Spells (0-30 damage) with full success but it would make less sense to use Spells that can go up to 100 Points of damage. A few spells will have your TOTAL SPELL POWER multiplied (i.e. to steal cash from another Player), also the HELL spells will affect not only the Province you cast them on but also its neighboring Provinces (neutrals too, but NOT your own Provinces, so you cant hurt yourself)
b> WHITE SPELLS : These are the "good" Spells, quite like the Potions. They have some defined positive result on the province you use them. See the "Book of Stone" and the "Book of Magic" for the details.
c> BLACK SPELLS : Fear them, as they will bring terror and pain if someone casts them on you. They are expensive to "produce", as they require the rarest and darkest stones and experienced Magicians. See the "Book of Magic" and the "Book of Stone" for details. Diamonds, Wood and Corn are not used during this Phase.
Of course you must possess the Province if you summon a Creature or use white spells. You cannot cast common spells or black spells on yourself. One Creature per Province is allowed. If there is a requirement to cast the spell (i.e. you need Tech Level 5 or better) you must meet this requirement or the spell will fizzle and be lost. The requirements are only meant when CASTING a spell and not when building it in a Phase later on.
A final word on using Creatures during this Phase : while the Creature is also a unit like every other, the level of the troops (see below) will NOT drop when activating it in a Province. This is due to the fact that they were magically summoned, so call them in a Province with a high battle level and you will make them even stronger. To say it again, when summoning a Creature this will NOT change the level of the troops !

These weapons were known as missiles in WOK4, some call them the "equalizers" of WOK. They are simply speaking arrows you can aim at a specific taget, i.e. on the Archers of a Province.
There are two types of GCA attacks : short-range will be when you attack a neighboring Province amd long-range occurs when you attack a non-neighbor which has a Province Number from -3 to +3 to yours. (as an example, Province#29 can aim long-range GCAs at all Provinces ranging from #26 to #32). However long-range attacks will only have 3/4 of the power of short-range attacks. 
Your chance to hit with your GCAs and the number of Units you destroy will depend on the Target you chose : while it is easy to burn some wood or kill a few Population it is much harder to be successful against armies or even Creatures or Magicians. See the respective chart for details. Also remember that if you attack a Mountain or a Forest Province you will have 5% less chance due to the difficult Terrain.

[04][1] simply means Phase#4, first Order. And next comes the important Part : for EVERY type of unit you can define with 1 Digit how many you want to use in the attack.Because there are 6 types of units this second brackets also holds 6 digits. 1-9 means of course "use 1 to 9 Units of this type", but there are also the letters X (for 10), T (for 25), L (for 50), C (for 100) and A for ALL UNITS you have of that type. In the example above we would use (up to) 10 Armies, 4 Pikists, no Archers, no Knights, All Catapults and the Creature in the Attack. [AAAAAA] would easily mean "use all units I have". This is enough to start your Attack, but it wouldnt be WOK5 if it didnt offer you some new option. You can now add 3 more Digits to your order (again: this is OPTIONAL, erase it if you dont use it) that will set a limit of unit losses. In our example this value is [012] units. So whenever you have lost a TOTAL of 12 Units during the battle your surviving troops will retreat !
And now on to the next part - the battle itself. 
* There is still a PATT and PDEF and they still add (level x 10)+(defense x 4), then multiply with your 0,EFF level (i.e. 95% EFF turns to EFF x 0,95). But you first need to understand that all troops and units share their level, called the basic level. Now will you ask, why should I make some Archers or Knights out of my Armies ? Because they give you EXTRA LEVEL during battle, but only if they fight on their preferred Terrain. Here is the corresponding chart :

Population is still the key factor in WOK V !!
40 POP = 1 MAG
4 POP = 1 ARM
5 POP = 1 SPY
2 POP = 1 WOK
and for the desperate Player :
1 MAG = 20 POP
2 WOK = 1 POP
Each round, you must again decide on how to "transform" your population into workers/armies/spies or even magicians (or put them back to POP if you need to do that). Only workers can build defenses, mine diamonds or harvest corn and only troops can do combat. But only population can grow to become more population and pay taxes !! In WOK5 you can now transform up to 60 units per order (in WOK4 it was 50) and if you dont put in a specific number the program will AUTOMATICALLY try to change the maximum possible. Of course you need a FULL number of i.e. 4 Population to be transformed into 1 Army. If you transform 5,6 or 7 Population into Armies you will get that same result but lose the unused surplus Population. There are still only 3 POP>ARM Transformations allowed every Turn, but now the program will simply neglect invalid/impossible POP>ARM transformations and not count them ! (This means you can put up to 7 POP>ARM orders in your turn, but only the first 3 VALID ONES will be done !)
You can also change back some Workers into Population (changing Workers into Armies is not allowed) but this option should only be used when facing extreme situations. The WOK>POP trade is done with a 2:1 ratio (like in WOK4).
The orders now also include the CHANGE AIM feature. In this case you need a (capital) LETTER after the Province# to tell the Manager the new aim and that the order is not a transformation. Here are a few examples :
[06][1][65][2] - change maximum of 60 POP into Armies (Province#65)
[06][2][14][H] - change Aim of Province#14 into (H)arvesting Corn
[06][3][17][4][80] - bad luck, youd like to transform 80 POP into 2 Magicians but you forgot that you are only allowed to transform 60 units at a time.... therefore you would get 1 magician and 20 POP would be wasted - but this is WOK5, the Manager will limit your used units in this case to 40 :)
To fully see what this phase is supposed to do refer to the AOF !

++ Phase VII gives us unit up- and downgrade possibility. First you need to choose the source province, next the number of units you wish to up/downgrade (up to 30 per order) and finally you enter TWO digits that describe the up/downgrade: every troop has a number from 1-5 so the order
[07][1][39][30][13]
would mean "upgrade 30 units of armies (1) into archers (3) in Province#39". Take care that UPGRADING a unit can only be done if you have the necessary wood in your stock, while DOWNGRADING (i.e. make some pikemen out of catapults) can always be done without any costs of wood. As there are only 6 orders possible with this Phase you will need to careful plan a few things, but I think you are used to that kind of stuff.... :)

++ Phase VIII and IX allows to move units from one Province to another. The only difference between Phases VIII and IX is that you can move 60 units in the Major and 30 units in the Minor Movement Phase. Each Phase allows for 5 orders, so you have up to 10 possible orders (in WOK4 there were only 7 orders, but we now have 10 Provinces more and a lot of units to take care of). Watch out that if two Provinces are related by a Bridge you can only move 30 units over it per order ! (This does not apply to attacks, only to movements)
The AOF again allows to omit the number of units to be moved - if you do so, the maximum (60/30) will be tried to move. You can move a specific type of unit (i.e. Magicians or Spies) but there is also the great possibility to move ALL TROOPS starting from the lowest to the highest (L>H) or vice-versa (H>L). Of course the movement of any type of military unit (creatures included) will always affect the Basic Level of the target Province.

++ A quick Phase - simply put the ID# of the Spell or Potion you wish to make and should you have enough of the required Diamonds, Gold and a free slot in your SPP then the Item will be placed in it. You can use a maximum of 3 orders in this Phase, but each order requires that you have another Magician that produces the item.

++ To say it in Monthy Pythons words : "And now to something completely different." Spying has evolved a long way in my mind since WOK4 and I was always decided to learn from past errors while bringing you something new and useful.
First of all SABOTAGE is gone - it wasnt used anyway and with such nice spells around in WOK5 there is no real need for it. Also every spy action will be done using ONE single spy now. Because Spies are now transformed out of POP at a ratio of 5:1 this really makes sense. The option "Spy full Player data" has been replaced by what is called the "SPYCODE" (see below for more details). If a spy fails to infiltrate a Province he will immediately be caught by the enemy, another measure to ease the pain of transforming POP into Spies...! Spies can also be detected when entering a Province and while they wont be caught then you will loose some EFF. The owner of the targeted Province always has (number of Spies *10)% chance to detect the coming spy (but at least 1%, as usual). Let me explain the 7 possible spying options you have in detail now :
<1>SEND UNIT REPORT: One spy will be sent to a Province and report back what he sees - this report can be more or less useful and should be considered as the easiest but also cheapest source of information. Your chance to infiltrate your target is equal to your EFF Level (or 3/4 of your EFF level if the target is not a neighbor). Once he successfully arrives he will always have his EFF Level (or 3/4 of it) of chance to bring back some information on a unit type. Should this go well he has 1/3 of a chance to get full information on the unit and, in some cases like Armies, another 1/3 to report something like "There are more armies here then where I came from". This process is repeated for every type of unit, so the reports may well vary.
<2>SEND STATUS REPORT: The procedure is the same, one spy is sent abroad to report on a few more or less important status statistics of the enemy. Your chance to infiltrate your target is equal to your EFF-10% Level (or 3/4 of your (EFF-10%) level if the target is not a neighbor). Once the spy successfully arrives he will always have the EFF-10% Level (or 3/4 of it) of chance to bring back some information. Should this go well he has 1/2 of a chance to get exact information on a status figure (i.e. the Tech Level. Magic resistance Level or total Population). The calculation is repeated for Race, EFF Level and MRES Level, Tech Level, Bank deposit, Stocks of Wood/Corn/Gold and total number of Population/Workers.
<3>SPY PROVINCE DATA: Yes. its still here, the good old spying out a Province ! This should be self-explaining, your chance to do the job will be your (EFF-15%) or 3/4 of it (if you spy on a Province that isnt a neighbor). Your gain/loss in EFF will be the same like when using the simple "Send unit report" option, but the information will be more valuable.
Now comes the spying options regarding the SPYCODE. The Spycode is a code that protects your entire Provinces data from being visible to other Players (similar to the Data you got in WOK4 when trying the "Spy Player" option). It can range from 0000 to 9999 and will automatically be assigned to you at the start of a new game. Now lets see what we can do with it :
<4>TRY SPYCODE: Each Turn you can use up to 2 of your 5 possible spying orders to try a spycode on all your fellow Players. There is no cost or danger involved in this, but all you will get is the notice if the code you entered was too high or too low (or hopefully just right).
<5>RUN SPYCODE: Once you broke a Spycode you might run it to get the enemys full data revealed to you. Should you fail (which means none of the other Players has the Spycode you just ran) you will loose 5% Effectiveness. Every time you run a Spycode all other Player will be acknowledged that you ran a code, but they will not know if you were successfull or if you failed - they also will not know on who the Spycode attack was directed... you will not gain any EFF bonus or anything else besides the full Player data from this action.
<6>SET SPYCODE: This final spying option allows you to modify your Spycode in case you are in danger of giving away too much information for too long. However you will loose a whopping 10% of your Effectiveness, so use this option only when you really need to. All Players need to have different Spycodes too - should your new code already be taken you will be noticed (and not loose any EFF).
<7>SET TRIBE: Now this is no "real" spying option, but it ended up anyway in this Phase. You can now choose to change your tribe affilation into another one, allowing maybe for a tribe that helps you better in a particular time of the game. The tradeoff : you loose 1/8 of your EFFectiveness level (rounded).

++ And last but never least another quick Phase - simply put the number, ID# (see Book of Magic) and price (for 1 Unit) of the Item you wish to sell and it will be placed on the Buylist of the Marketplace. You can fill up to 5 slots with your products. Take care that these items now no longer count for the Stock Limit, but they will count again after Phase 1 of the next Turn in case they arent sold to the other Players.
