  • Defiance of the Fall
  • Completionist Chronicles
  • The Wandering Inn

Perfect for you if...

  • You enjoy LitRPG stories where the protagonist has to learn systems from scratch rather than being instantly competent.
  • You like dungeon-building mechanics mixed with character progression and strategic thinking about monster placement.
  • You appreciate humour grounded in a character's genuine confusion rather than winking at the reader.

Maybe not for you if...

  • You want rapid-fire action and combat as the primary focus rather than dungeon design and probability calculations.
  • You prefer self-insert fantasy where the protagonist's hidden talents are immediately recognised by everyone around them.
  • You find gacha mechanics and drop-rate discussions tedious rather than interesting system-building elements.

About this book

This collection contains all three books in the Serious Probabilities Series: Dungeon of Chance: Even Odds, Dungeon of Chance: Double or Nothing, and Dungeon of Chance: All-In. In a world governed by probabilities, Clay Shuntwise lives as a teenager running deliveries for his family's shop in the town of Renton. Thousands of Heroes protect the land by defending against periodic invasions of giant monsters called World Threats. Clay's ordinary life changes when a World Threat crashes down on him. Reborn as a Dungeon Core, Clay must learn how to navigate his new existence. A dragonling guide attempts to help him understand dungeons and Heroes, assuming that as a former Hero, Clay would already know the fundamentals. However, Clay was never actually chosen to be a Hero in his past life. Now he must learn about the relationship between Heroes and dungeons, including probabilities and drop rates, while struggling to survive in his unexpected new form. The series features Dungeon Core, LitRPG, and GameLit elements including dungeon construction and defense, monster summoning, character progression, and a game-like interface. The world's probabilities operate similarly to Gacha-type mechanics. The books contain no profanity, harems, or explicit sexual content.
