1.0 Introduction
This document specifies the requirements for the production and design of the Game
Suite software for the Google Android operating system. The product will be a suite of
five simple and easy games for a user to play. The games include a word search, connect
four, battle ship, hangman, and a Sudoku. The first four games will be uniquely
developed and the fifth will use an open source Sudoku. The user interface will be easy to
use and allow the user to go in-between games with ease. It will use the cell phone
operating system Android, which is on a lot of cell phones today. The android operating
system uses a market place to sell applications for the phone.
1.1 Goals and objectives
The goal of this project is to produce an interactive and entertaining application
for the Android marketplace. This app will be a suite of several smaller games,
one of which is open source, the rest custom made. They will be playable on any
phone supporting the android operating system with access to the internet.
1.2 Statement of scope
The only input to this project is the user's attention and strategic moves; and the
only output is the entertainment that is a consequence of the input.
1.3 Software context
The big picture of this project will be to provide entertainment for anyone with
access to an Android device.
1.4 Major constraints
Since this project can easily be broken down into many smaller functioning parts,
there are few major constraints. As long as the Android Marketplace is up and
running and people are still using the Android OS, it will be possible to market,
maintain, and operate this application.
2.0 Usage scenario
2.1 User profiles
Users of the system will be anyone who has a mobile device operating the
Android OS with access to the Android Marketplace. The application will be
accessible to everyone by these means and require only navigation of the menus
and games through the touch-screen interface.
2.2 Use-cases
Figures one and two show the different use cases for the game suite. Figure one
show the interaction between the user and the Android OS. Figure two show the
interaction between the user and the main menu.

Figure One: Use Case Diagram for interaction with the user and the Android OS
Figure Two: Use Case Diagram for interaction with the user and the main menu
3.0 Word Search
3.1 Data Description
The word search utilizes a couple of different data objects. These objects are used
for passing data around and keeping track of information. The data keeps track of
selected letters, selected words, and game scores.
9
3.1.1 Data objects
The first data object is the user. The user will select letters to make words
for the word search. The letter themselves are characters. Multiple selected
letters are formed to make a string. Once the user is content with the
selected word, it can be submitted to check if it is actually a word.
The second data object is the collection of selected words. These words are
stored in the form of a string and an array of tiles. If the submitted word is
correct it is appended to the collection of selected words. If it is wrong
then the word is discarded.
The third data object is the final score when the game is ended. The score
is calculated by counting the number of letters submitted in the selected
words. The game will locally keep the highest score for display.
3.1.2 Relationships
The relationships between the data objects above can be seen in the figure
below. The user will submit data and the program will pass around that
data.
3.1.3 Complete data model
Figure three: Word Search Complete Data Model
3.1.4 Data dictionary
All the data except for the high score is only stored when it is running.
Once the program is ended all data will be discarded. The high score will
be stored on the phones memory and shown at the startup screen.
3.2 Functional Model and Description
3.2.1 Description for Functions
3.2.1.1 Startup
10
This function is initiated when the word search game is pressed
from the home screen. The function starts a new activity that
shows the main menu for the game.
3.2.1.2 New Game
This function is initiated at the initial screen when the new game
button is pressed. After the button is pressed, it creates a random
puzzle, draws the board, then passes of the responsibility to the
main game function.
3.2.1.2.1 Create Random Puzzle
When a new game is started, this function randomly
picks 81 numbers. The range of the numbers is 0 to
25 and is then converted to character to represent a
letter. The letters are then stored in an array.
3.2.1.3 Main Game Function
After a new game is started, the main game function runs
functions to watch the user actions and act accordingly.
3.2.1.3.1 Draw the Board
Every time an action or function is called the board is
redrawn to show the changes. The function draws a
9x9 board with the letters inserted into each position.
The function looks at an array to see which words
were already correctly selected. These words are
drawn a different color.
3.2.1.3.2 Select Letters
This function is supported by the android
onclicklistener. When a user selects a letter, it records
it in an array. It keeps track of the order that the user
presses the letters in.
3.2.1.4 Menu Functions
During the game the user can press the menu button to bring up
options. The menu option is used to conserve space on the screen.
3.2.1.4.1 Submit a Word
After letters are selected the user can submit the word
to see if it is a correct word. The function calls
dictionary check and gets the result. If it is a word,
then the word is added to the submitted word data
object. If it is not a word, then the screen shakes. After
the word functions are done, the selected is cleared
with the clear function.
11
3.2.1.4.1.1 Dictionary Check
When a word is passed into this function it uses the
Google online dictionary search. It gets the source
page of the search and parses it to see if the word is
in the dictionary. It returns the result.
3.2.1.4.2 Clear the Board
This function clears the board of the selected letters.
3.2.1.4.3 Help
This function displays the rules of the game.
3.2.1.4.4 View Submitted Words
This function displays the words that have been
submitted and that were in the dictionary.
3.2.1.4.5 Finish Game
This function ends the current game and takes the
user to the main menu of the game. The function uses
the calculate score function then displays the score of
the game. It ends the new game activity.
3.2.1.4.5.1 Calculate Score
This function calculates the final score of the
game. It does this by counting the number of
letter in the submitted words data object.
3.2.1.5 High Score
When a game is finished and the score is calculated, the score is
compared to the high score. The higher score is then stored on the
phone. The high score is displayed on the main screen of the game.
3.2.1.6 Exit Game
This function exits the game’s main menu back to the game
suite’s main menu.
3.2.2 Software Interface Description
Word search uses one interface that the user can see. The one that they see
is through the cell phone. The cell phone must be running the Android
operating system. The game also interfaces with Google web dictionary
search, but it is not seen.
3.2.2.1 External machine interfaces
The game will run on two different machines. One is an emulator
of a cell phone that is used for development and testing. The other
12
is the user’s cell phone that hosts the game. The game must be
compatible with the Android operating system.
3.2.2.2 External system interfaces
To play the game, the user must be connected to the internet either
through the phone’s data network or Wi-Fi. The Google web
dictionary search is to check to make sure the word exists and is
not seen by the user.
3.2.2.3 Human interface
This is the main interface that the user will interact with. The
interface will allow the user to use the phones touch screen
services and analog buttons. This interface is clear and easy
to use. It shows buttons and text so the user can understand
what is going on.
3.2.3 Control flow description
The control flow of the word search starts when the user starts a new
game. After the new game is started there will be different states of the
game. This continues till the game is finished. This described in section
5.0 and its subsections.

6.0 Word Guesser
6.1 Data Description
The word guessers utilizes a few different data objects each of which are uses for
passes data around the program and keeping track of information. The data keeps
track of the correct answer to the word guess as well as each individual character
within the answer, each individual word – also tracking each individual character
within each guess, as well as the number of individual guesses.
6.1.1 Data objects
The first data object is the new game. Once the word guess application is
selected from the home screen a new game is initiated with an answer, a
guess count, a guess array and a Boolean correctness field. Each element
of the guess array is a character array so that each letter of each guess can
be compared to the correct answer. There will be a button at the bottom of
the UI which will allow the user at any point within the running of the
program to create a new game, at which time the previous game will be
overwritten.
23
The next data object is the answer. The answer will be generated at the
beginning of each new game accessing a predefined list of six letter words.
The answer will be stored in an array of characters.
The third data object is the guess array. The guess array will consist of six
elements each of which is a character array. It will be generated from an
Edit Text field submitted by the user. If the guess is a valid word (I.e. has
six characters, and all characters are letters) then the guess will be
converted to a character array and added to the guess array. Otherwise the
guess will be ignored, the user will be prompted of the mistake and will be
able to submit another guess.
The final data object will be the final score when the game is ended. The
score is calculated by counting the number of words correctly answered
before ending the game, multiplying that number by one thousand and
subtracting the number of guesses taken multiplied by 50. The game will
locally keep the highest score for display.
6.1.2 Relationships
The relationship between the data objects above can be seen in the
following figure. The user will submit data and the program will process
that information accordingly.
6.1.3 Complete data model
Figure eight: Word Guesser Complete Data Model
6.1.4 Data dictionary
24
All of the data excluding the word dictionary will be stored on when the
program itself is running. Once the program is stopped, or a new game is
initiated, all data will be discarded. The word dictionary will be stored on
the phones memory and will be accessed at each initiation of a new game,
at which time a random word will be selected as the answer for that
particular game.
6.2 Functional Model and Description
6.2.1 Description for Functions
6.2.1.1 Start Up
This function in initiated when the word guesser game is pressed
from the home screen. The function starts a new activity that shows
the main game screen for the word guesser.
6.2.1.2 New Game
This function in initiated once the word guesser button is pressed
from the game suite home screen and when the new game button is
pressed from the menu of word guesser. Once the button is pressed,
a new answer is selected from the word dictionary, the guess array
is reinitiated to the default values, the guess count is reset to zero
and the correctness field is set to false.
6.2.1.2.1 Answer Generator
When a new game is started, a random number between 0
and 600 is generated at which time the program traverses
the word dictionary for the generated amount of interactions
and returns that word as the correct answer for the game.
6.2.1.3 Main Game Function
After a new game is started, the main game function runs functions
to watch the user actions and act accordingly.
6.2.1.3.1 Submit Guess Function
Each time the OK button located adjacent to the Edit Text
field is selected a function is called to first check the
validity of the guess (i.e. current length and correct
characters). This guess is first stored as a String; however,
will be passed through the split() function to create a
character array of the guess for comparison.
6.2.1.3.2 Split Functional
Once the guess string is retrieved from the Edit Text field,
this function is called to create a character array of the
guess. A string is passed to the function and a character
array is returned. This function is also used for the correct
25
answer of the game which is generated from the word
dictionary.
6.2.1.3.3 Compare Function
Once the correct answer and the individual guess are
submitted, those two character arrays are passed to the
compare function to determine the correctness of the guess.
Each character within the guess array is first compared with
the character in the corresponding position of the answer
array. If those two characters are alike then the setColor()
function is called and the character is printed red. If those
two characters are not alike the guess array character is then
compared to every other character within the answer array.
If that character is found in the answer array then the
setColor() function is called and the character is printed
yellow – signifying that the character is in the answer, but
not in the correct position. If the character from the guess
array is not found in the answer array then the character is
left as is.
6.2.1.3.4 Set Color Function
This function is called within the compare function. The
guess character array, an index identifying which element of
the array is being manipulated and integer value signifying
which color to set the text to be passed to the function. The
return value of the function is void.
6.2.1.4 Menu Functions
During the game the user can press the menu button to bring up
options. The menu option is used to optimize screen space,
avoiding clutter.
6.2.1.4.1 Help
This function displays the rules of the game.
6.2.1.4.2 New Game
This function ends the current game and resets all data to
default values within the word guess game screen. All
previous data, other than the word dictionary, are destroyed.
Selecting this option will nullify the possibility to store the
game score.
6.2.1.4.3 View High Score
This function displays the current high score for the word
guess game as well as the score of the current game for
comparison.
26
6.2.1.4.4 Finish Game
This function is very similar to the New Game function;
however, rather than taking the user back to the word guess
game screen, the user is returned back to the game suite
home screen as well as the final score being calculated and
submitted to the system. It ends the new game activity.
6.2.1.4.4.1 Calculate Score
This function calculates the final score of the game.
It does this by counting the total number of correct
answers without ending the game multiplied by
1000 and subtracting the total number of guesses
multiplied by 50.
6.2.1.4.4.2 High Score
When a game is finished, either by the user
incorrectly guessing six consecutive times or by
selecting finish game in the menu, the score is
calculated and compared to the current high score.
The higher of the two scores is stored onto the phone
and displayed in the high score option of the menu.
3.2.1.5 Exit Game
This function exits the word guesser game screen and returns back
to the game suite's main menu.

8.0 Restrictions, Limitations, and Constraints
The application is being developed for the Android operating system and as such should
be compatible with at least the majority of the current versions of Android which are 1.1,
1.5, 1.6, 2.0, and 2.0.1. The application must be designed to display correctly on the wide
range of mobile phones which run the Android operating system. The overall application
and its individual parts must be designed to run smoothly and quickly on the relatively
limited processing power of mobile devises.
9.0 Validation Criteria
Validation for the application will mostly be focused around the end user use case. While
not all possible scenarios can be tested validation will consist of testing a reasonable
number of cases to declare that all cases should work.
9.1 Classes of tests
9.1.1 Welcome Screen
37
- Move between the Welcome screen and the available games multiple
times and in varying orders.
9.1.2 Word Search
- Select known valid words for multiple puzzles.
- Select known invalid words.
- End game, exit program, and re-launch.
9.1.3 Connect Four
- Run through multiple games from start to finish with varying end
game scenarios.
- Exit program mid game and re-launch.
9.1.4 Battleship
- Run through multiple games from start to finish with varying end
game scenarios.
- Exit program mid game and re-launch.
9.1.5 Hangman
- Run through multiple games from start to finish with varying end
game scenarios.
- Exit program mid game and re-launch.
9.1.6 Sudoku
- Run through multiple games from start to finish with varying end
game scenarios.
- Exit program mid game and re-launch.
9.2 Expected software response
9.2.1 Welcome Screen

- Individual 'shots' should register as hits when they occur at a location
occupied by an opponent’s ship. The game should end when all enemy
ships have been destroyed
- Game should open and close cleanly and high score should be
persistent when re-launching.
9.2.5 Hangman
- Individual letters should register as being part of the target word if they
are. Incorrect letters should result in the addition of a body part to the
'hangman'. The game should end when either the 'hangman' is complete or
the target word is completed.
- Game should open and close cleanly and high score should be
persistent when re-launching.
9.2.6 Sudoku
