Use TDD to create classes that would be used to build a scrabble game. Don't actually build an interactive game (yet)!
From the project root, you should be able to execute all of your specs by just running rspec
. All of your classes should be in their own files in lib/
, and the entire project should be namespaced in a module called Scrabble
.
Your spec descriptions should be meaningful and organized into context
blocks that reflect your intent on how to use the code.
Do not move onto a new tier of requirements until the minimum requirements of the previous tier are complete and your specs are green across the board. Use TDD to drive your development and document your edge cases.
Create a Scrabble
class with a minimum of 8 specs. The class should have the following class methods:
self.score(word)
: returns the total score value for the given word. The word is input as a string (case insensitive). The chart below shows the point value for a given letter.self.highest_score_from(array_of_words)
: returns the word in the array with the highest score.- Note that it’s better to use fewer tiles, so if the top score is tied between multiple words, pick the one with the fewest letters.
- Note that there is a greater bonus for using all seven letters. If the top score is tied between multiple words and one used all seven letters, choose the one with seven letters over the one with fewer tiles.
- If the there are multiple words that are the same score and same length, pick the first one in supplied list
Letter | Value |
---|---|
A, E, I, O, U, L, N, R, S, T | 1 |
D, G | 2 |
B, C, M, P | 3 |
F, H, V, W, Y | 4 |
K | 5 |
J, X | 8 |
Q, Z | 10 |
Create a Player
class with a minimum of 11 specs. The class should have the following class and instance methods:
self.new(name)
: creates a new instance with the instance variablename
assigned#name
: returns the@name
instance variable#plays
: returns an Array of the words played by the player#play(word)
: Adds the input word to theplays
Array- Returns false if player has already won
#total_score
: Sums up and returns the score of the players words#won?
: If the player has over 100 points, returnstrue
, otherwise returns 'false'#highest_scoring_word
: Returns the highest scoring word the user has played.#highest_word_score
: Returns thehighest_scoring_word
score.
Create a TileBag
class with a minimum of 5 specs. It should have the following class and instance methods:
self.new
creates an instance with a collection of default tiles#draw_tiles(n)
returns n number of random tiles, removes the tiles from the default set.#tiles_remaining
returns the number of tiles remaining in the bag
Create specs for (minimum 2) and add to the Player
class the following instance methods:
#tiles
a collection of letters that the player can play (max 7)#draw_tiles(tile_bag)
fills tiles array until it has 7 letters from the given tile bag

- Create a
Dictionary
class that includes a method for searching a list of words to determine if a given word is a valid word. - Create a
Board
class that has a matrix (array of arrays) of tile places. Check if a word can be played on a given tile place in a certain direction. - Include a minimum of 20 specs between the
Dictionary
andBoard
classes.
