Welcome to the Yahtzee Scoring Kata! Your task is to implement a scoring system for the game of Yahtzee. The goal of this exercise is to write clean, well-tested code while considering different approaches and refactoring opportunities.
You are given a function best_score(roll) that takes a list of five dice rolls (each a number from 1 to 6) and returns the highest possible score and category for that roll. Your task is to implement or improve the function while maintaining correctness.
- Ensure your code returns the correct score for all Yahtzee scoring categories.
- fork this repo and open a PR with your proposed changes. We will discuss your approach and decisions in an in-person interview.
Yahtzee scoring is divided into Upper Section and Lower Section categories. The function should evaluate the given dice roll against all categories and return the one that provides the highest score.
| Category | Scoring Rule |
|---|---|
| Ones | Sum of all 1s |
| Twos | Sum of all 2s |
| Threes | Sum of all 3s |
| Fours | Sum of all 4s |
| Fives | Sum of all 5s |
| Sixes | Sum of all 6s |
| Category | Scoring Rule |
|---|---|
| Three of a Kind | Sum of all dice if at least three match |
| Four of a Kind | Sum of all dice if at least four match |
| Full House | 25 points for three of one number + two of another (e.g., 2-2-3-3-3) |
| Small Straight | 30 points for four consecutive numbers (e.g., 1-2-3-4) |
| Large Straight | 40 points for five consecutive numbers (e.g., 2-3-4-5-6) |
| Yahtzee | 50 points for five of a kind (e.g., 5-5-5-5-5) |
| Chance | Sum of all dice (no restrictions) |
- A working implementation of
best_score(roll), following the scoring rules above. - Identify areas for improvement in readability, maintainability, or performance.
