From the introduction: The Second Chance system powers solo role-playing games, which are designed to fit on a single page. Games utilize something to record journals such as paper and pen as well as a d20 and a d6. Each game is divided into a series of turns known as Moments. At the start of each turn, the player rolls the d20 and consults the chart to determine what event or reflection their character will undergo. The key mechanic of these games, known as the Twist, occurs when the player rolls a prompt more than once. Here, the player must reveal something previously unknown, uncertain, or intentionally hidden about the previous entry for that prompt. Finally, games utilize a Goal tracker, which certain prompts may increase or decrease. When a Twist occurs, the player must roll the d6 and compare it against the Goal tracker, often determining success, failure, or the conclusion of the game.
