How we work together
- We treat each other with kindness, consideration and respect
- We focus learning and practicing craft over getting things done
- We verify the correctness of code using Test Driven Development (TDD)
- We work collaboratively (mob/pair)
- We use retrospectives to improve

Mancala

Setup:
- The game starts with 4 stones in each of the 12 small pockets
- Each player controls the 6 pockets on the side closest to them
- The two larger pockets are called mancalas.
- Each player controls the mancala to the right of their row.

Rules:
- On your turn pick any pocket on your side of the board.
- Pick up the stones in that pocket and distribute them counter clockwise, one in each pocket that you pass, until you run out of stones
- If you run into your own mancala distribute one stone in it.
- If you run into your opponents mancala, skip it

More Rules:
- If the last piece you drop is in your own mancala take another turn immediately
- If the last piece you drop is in an empty pocket on your side of the board you capture that piece and any pieces in the opposite pocket.
- Place all captured pieces in your mancala

The end:
- The game ends when all pockets on one side of the board are empty
- The player who still has pieces on their side of the board when the game ends captures all those pieces
- Count all the pieces in each mancala. The player with the most pieces wins!

Coding Mancala:
Represent the board as an array of integers:
[4,4,4,4,4,4,0,4,4,4,4,4,4,0]
Player 1's mancala
Player 2's mancala

Coding Mancala:
Knowing the state of the game also requires knowing who's turn it is:
{player: 0, board: [4,4,4,4,4,4,0,4,4,4,4,4,4,0]}
