Game of Risk, final version
Posted: Mon Nov 12, 2018 11:24 am
For now this is the final version. Perhaps a choice from some difficulty levels will be added, but not in the coming period. Please read the help info included in the program about how to fiddle somewhat with the strength of the 5 AI (artificial intelligence) players in the game.
Since the first version, the following facilities have been added to the game:
- a startup screen with option choices
- initial placement of armies at random or by the human player (classic)
- possibility to save the actual game and resume it later on
- in-game helpfile in a scrolling window
- some internal refinements and removal of some flaws
As the helpfile has been modified, two files must be copied, the code file and a data file.
The data file is named "risk_data" and must reside in the same directory as the program.
The code file:

"The game of Risk
"
"
"
"I play the game of Risk on the iPad quite a lot. Currently "
"there are many Risk like games in the App store. I have a "
"nice version from EA (Electronic Arts), but it is "
"discontinued and does not run under iOS 12 on my new iPad. "
"Hence i programmed my own version now in SB. That also gives "
"the possibility to improve some mechanisms that i considered "
"to be less favourable.
"
"
"
"In this little document, the characteristics of the game are "
"described only as far as they differ from the generally used "
"gamerules. If you never played Risk and want to give this "
"one a try, you are advised to first learn about the game in "
"Wikipedia.
"
"
"
"What's different, compared to the usual game rules.
"
"
"
"The battle order.
"
"This version does not use dices to establish a battle "
"result.
"
"A battle consists of a number of turns. Each turn one army "
"is wasted, be it from the attacker or from the defender. The "
"result is based on a random selection, with the odds "
"calculated as the quotient between the atackers strength and "
"the defenders strenght. The attackers strength is simply the "
"total number of armies in his state. The defenders strength "
"is a virtual number of armies, calculated as the product of "
"the actual number of armies and a defence strength factor.
"
"It is assumed that a state builds defence infrastructure "
"during each year that it is owned by the same player. This "
"results in a defence multiplier that starts with value 1, "
"grows slow in the early years, and stabilizes at a maximum "
"value of 3.
"
"Army losses at the defenders side are deducted from the real "
"number of armies.
"
"After each battle turn, the odds are calculated again for "
"the next turn.
"
"If the last army of the defender is lost, the state is taken "
"over by the new owner. All defence infrastructure is assumed "
"to be destroyed in the battle, hence the defence strength is "
"set back to a value of 1.
"
"One other difference is that only 1/3 of the remaining "
"attacking armies are automatically moved into the taken "
"state. Attacking other states with this occupation force is "
"allowed, but taking many states like 10 or more in one turn "
"by the same army is no longer possible.
"
"
"
"Economic strength.
"
"Each state has an economic strength factor which reflects "
"the importance of the region in the real world. The strength "
"factors range from 0.1 (for Greenland) to 0,9 (west- and "
"east US, for instance).
"
"At the start of each game turn, each state produces an "
"amount of new armies equal to it's economical strenght. "
"Those newly enlisted armies cannot be placed at will by the "
"player, but start off in the state where they are produced. "
"The player gets bonus armies for continents and for victory "
"cards with a minimum of one army. Thos armies can be placed "
"freely.
"
"The total economic strength of all states of a player is "
"also used to calculate the maximum number of move units "
"during the fortify phase. One move unit is a move of one "
"army from one state to a neighbour state.
"
"
"
"Victory cards.
"
"Like in most Risk games, the player gets a card when his "
"attack phase is concluded with at least one state takeover. "
"In this version of Risk, all cards are the same. If at the "
"start of the draft phase the number of cards is 5 or more, "
"sets of 3 cards are converted into 10 armies until the "
"number of cards is less than 5. As usual, when a player "
"looses his last state, his cards are transferred to the "
"player who took that last state.
"
"
"
"Playing the game.
"
"
"
"Startup screen.
"
"The game starts displaying a startup screen. The upper "
"switch is in the position 'new game'. If a saved game exist, "
"it can be resumed by switching the switch. In both cases the "
"second line on the screen tells the human player his number "
"and color in the game. There is one human player and 5 AI "
"(Artificial Intelligence) players at the start of the game, "
"hence 6 in total, every player having his own color.
"
"The third line is for future use and is meant to choose a "
"difficulty level. The actual level of the AI players is "
"about medium.
"
"The fourth line has a switch wich can be used to select the "
"method of initial placement of 13 armies. The classic way "
"leaves the placement to the player, the alternative is to "
"let it be done at random by the game. Choosing to place the "
"armies yourself means a serious decrease in difficulty "
"level, as you probably can secure a 'strong point' "
"(continent) from which to expand further.
"
"After hitting the 'start' button the game starts.
"
"
"
"A game round.
"
"Unless you have player number 1 (with color red), the AI "
"players take their rounds, placing an army somewhere, "
"attacking other players, and moving armies in the fortify "
"phase of their turn. At some point, the animations stop and "
"the 'Play' button shows your color. It's your turn.
"
"
"
"Draft phase:
"
"You get at least 1 army per turn, augmented with additional "
"armies if you occupy one or more entire continents, or if "
"victory cards are converted into armies. Those extra armies "
"may be assigned freely to your states.
"
"To assign one or more armies to one of your states, first "
"select a state by touching the button in the state, then use "
"the arrow buttons in the middle of the screen to augment or "
"to decrease the shown amount of armies. The counter is a "
"closed loop: decreasing under zero produces the maximum "
"number available, augmenting a maximum gives zero on the "
"counter. When satisfied, touch the ok button. If nothing "
"happens, you might not have made a proper selection. When a "
"selected state is selected again, it is deselected.
"
"You may select states and assign armies to them as long as "
"the available number is non-zero. You must touch the "
"progress button at the right side to switch to the attack "
"phase.
"
"The AI players follow the same rules and have the same "
"quantity rights as the human player, but they assign the "
"additional armies in a dumb way. They don't look at the "
"situation of enemy neighbour states.
"
"
"
"Attack phase:
"
"When attacking a state, all available armies in both states "
"are participating in the battle. As told before, for the "
"calculation of the odds, the amount of defensive armies is "
"augmented by a multiplier, which can be as high as 3.
"
"Based on the calculated odds, a series of successive rounds "
"is performed, each round causing the loss of one army, "
"either from the attacker, or from the defender. The "
"attacker, be it human or AI can follow the battle progress "
"and can abort the battle if the result so far is not looking "
"good. Before attacking you see the number of armies in each "
"state. With a toggle button 'Strength' you may have a peek "
"at the defence strength of each state; the multiplier factor "
"has a value of 1/3 or less of the shown values.
"
"If you decide to attack a state (which must be a neighbour "
"state), first select your state with wich to attack, then "
"select the ennemy state to be attacked. The selection can be "
"undone or changed by selecting already selected states "
"again.
"
"When done, touch the start button.
"
"You can follow the result of each attack and the number of "
"remaining armies for atacker and the defender. The speed of "
"the battle can be set to slow or fast with the 'slow/fast' "
"toggle button (default is 'slow'). Only the attacker can "
"decide to abort the battle using the start/stop toggle "
"button.
"
"If the battle results in defeat of the attacked state, the "
"state turns to the new owner, and 1/3 of the remaining "
"attacking armies flow into the taken state. The attacker "
"gets a victory card for the current turn if he had not so "
"far. The defence strength of the taken state is set to 0 "
"(which generates a multiplier value of 1).
"
"If the attacker takes the last state of another player, all "
"victory cards of the defeated player are transferred to the "
"victorious player.
"
"You can terminate this phase by touching the button on the "
"right side to switch to the fortify phase.
"
"AI players first will construct a table containing all their "
"states and the quotient of the number of attacking armies "
"and the number of defending armies of each of the neighbour "
"states. They ignore the defence strength of the defending "
"states (otherwise they become too intelligent for this fixed "
"AI level). Then the list with attacking options is sorted in "
"order of decreasing odds. They then perform a number of "
"battles of the top of the list.
"
"At initialization time, each of the AI players have been "
"assigned random values of the number of states they are "
"allowed to attack per turn, the level of odds needed to "
"start an attack, and a criterion when a battle will be "
"aborted. In this way, very different characters of AI "
"players may occur. This initialization is done within a "
"specific function for that purpose, displayed in yellow in "
"the beginning of the code. You can play with that to create "
"your own AI players.
"
"
"
"Fortify phase:
"
"In this phase, armies may be moved from states to neighbour "
"states. You get a maximum number of army movements allotted, "
"depending on the number and economic strength of your "
"states. Within this maximum you can make many moves.
"
"The proces of moving is the same as that of attacking, be it "
"that the secondly selected state is now one of your own "
"(neighbour) states. The plus and minus buttons work the "
"same, and the remaining quantity of allowable army movements "
"is visible. A selected move is effectuated by touching the "
"ok button.
"
"AI players have no limitation on army moves. They don't take "
"the situation of other player's armies in consideration. "
"They try to balance the amount of armies over their states, "
"with one exception: they will radiate out armies from states "
"that are surrounded solely by friendly states.
"
"In the fortify phase, the game may be quitted using the red "
"'X' button in the right upper corner. The game is then saved "
"and may be resumed at a later time."
