This document outlines Peter Kofler's coding dojo on tic-tac-toe. The dojo focuses on collaborative coding through a ping-pong process where one developer writes a test and the other writes code to pass the test. The dojo structure includes introductions, coding sessions, breaks, and retrospectives. The exercise is to collaboratively code a tic-tac-toe game through the ping-pong process while focusing on quality over speed.
