Setup

$ git clone https://github.com/makersacademy/pairing_exercises.git
$ cd pairing_exercises
$ bundle install

Instructions

1. Decide in your pairs when to rotate driver and navigator:

   • by setting a 15 min timer
   • by passing a test

2. Focus on passing 1 test at a time - discuss your approach and implement Scrabble#score!

3. We'll have a short ten minute reflection halfway through.

   • What's going well?
   • what can you improve on?

4. We'll reflect on the exercise at the end

Task

Given a word, compute the scrabble score for that word.

Letter Values

You'll need these:

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

Examples "cabbage" should be scored as worth 14 points:

• 3 points for C
• 1 point for A, twice
• 3 points for B, twice
• 2 points for G
• 1 point for E

And to total:

3 + 21 + 23 + 2 + 1

= 3 + 2 + 6 + 3

= 5 + 9

= 14

Extensions

You can play a double or a triple word.
