This is a sample of a Rulebook Red Team ambiguity audit, run on a synthetic rulebook I wrote for demonstration. The rulebook is titled 'Forage & Feast: A Card Game of Wilderness Cooking' and is approximately 6 pages. The findings below are real outputs from the audit process. No real designer's work is represented.

Rules Ambiguity Report: Forage & Feast
Manuscript received: 2026-08-20
Pages: 6
Components provided: Card list (42 cards), no board or icon key
Scope: Text-and-logic audit only. This report does not evaluate balance, fun, or physical component usability. Recall is unknown: we cannot tell you what fraction of real ambiguities we caught. This is a complement to blind playtesting and a human rules editor, not a replacement for either.
1. Contradiction Register
Each finding quotes the exact source text with page/section. If any quoted passage does not appear in your manuscript, tell us and you get a corrected pass or full refund.
Finding 1.1 — Starting hand vs. draw step
- Page 2, Setup: “Each player starts with 5 Rations cards.”
- Page 4, Your Turn: “At the start of your turn, draw 2 Rations cards from the supply.”
If players begin with 5 cards, the supply is not defined—do those 5 come from the supply? Does the supply start with a fixed number? The rulebook never says. Also, the term “Rations cards” on page 2 vs. “Rations cards” on page 4 is consistent in spelling but inconsistent in capitalization with other card references (e.g., “Ingredient cards” is capitalized on page 3). Minor but worth flagging.
Finding 1.2 — Ingredient play limit
- Page 3, Card Types: “You may only play one Ingredient card per turn.”
- Page 5, Cooking Phase: “During the Cooking Phase, you may play any number of Ingredient cards.”
The Cooking Phase is part of a turn. The two sentences directly contradict each other. The designer likely intended the Cooking Phase to allow multiple Ingredients, but the earlier sentence needs an exception or removal.
Finding 1.3 — Recipe scoring
- Page 6, End of Game: “The player with the most Recipe cards wins.”
- Page 6, Scoring: “Each Recipe card is worth 2 points. The player with the most points wins.”
Two different win conditions. If ties are possible on points, the first statement is silent. Which one governs?
2. Term Audit
Terms that are undefined, inconsistently used, or silently synonymous.
| Term | Issue | Location |
|------|-------|----------|
| Supply | Used but never defined. Does it include all cards not in players’ hands? Is it a shared pool? | Pages 4, 5, 7 |
| Cook | Used as a verb (“Cook a meal”) on page 2, as a noun (“The Cook is the player with the most Recipe cards”) on page 6. | Pages 2, 6 |
| Rations / Ration cards | Capitalized inconsistently. Also, “Rations” appears alone on page 4 (“draw 2 Rations”) but “Rations cards” elsewhere. | Throughout |
| Meal | Introduced on page 5 (“Cook a Meal”) but never defined. Is a Meal a set of Ingredient cards? A separate card type? | Page 5 |
| Forage | Used as a phase name (“Forage Phase”) but also as a verb (“forage for cards”). No rules for what happens during the Forage Phase beyond drawing. | Pages 3, 4 |
Proposed glossary additions: Supply, Cook (noun), Meal, Forage Phase.
3. Unresolved-Case List
Organised by game phase. Each case is a situation the rulebook does not address.
Timing and Priority
- Simultaneous triggers: Two players both have a “Mushroom Forager” card that says “When a Mushroom card is played, you may draw one card.” Who resolves first? No turn order tiebreaker is given.
Empty Deck
- Recipe deck empty: The rulebook says to draw from the Recipe deck during setup and certain effects, but never says what happens if it runs out. Does the game end? Do players reshuffle discards?
End-Game Trigger Conflicts
- Two end conditions: Page 6 says the game ends when the last Recipe card is claimed. But the same page also says it ends when any player reaches 10 points. Which fires first? If both happen on the same turn, which takes precedence?
Illegal-Move Recovery
- Played an Ingredient card outside Cooking Phase: The rulebook says “you may only play one Ingredient card per turn” (contradicted, but assuming the intended restriction). If a player accidentally plays one during the Forage Phase, what happens? No remedy stated.
4. Text-vs-Component Mismatch
Checked against the card list you supplied.
- Card #14 “Wild Garlic” — Card text says “Heals 2 HP.” Rulebook page 5, example: “Wild Garlic heals 3 HP.” Mismatch. (Note: HP is not defined in the rulebook; it appears only on cards. This is also a term-audit gap.)
5. Teach-Order Critique
First-play path as presented: Setup → Card Types → Turn Structure (Forage, Cooking, Discard) → End of Game.
Problem: The Cooking Phase is explained on page 5 before the player knows how to acquire Ingredient cards (page 4, Forage Phase). A new player will read about cooking a meal before they know how to get ingredients. Recommended order: Setup → Forage Phase (how to get cards) → Card Types (what you can get) → Cooking Phase (what to do with them) → End of Game.
6. Drafted FAQ Entries
In your rulebook’s register.
Q: Can I play an Ingredient card on my opponent’s turn?
A: No. Ingredient cards can only be played during your own Cooking Phase (page 5). The restriction on page 3 (“one per turn”) applies only outside the Cooking Phase.
Q: What happens if the Recipe deck runs out?
A: The rulebook does not specify. We recommend: If the Recipe deck is empty when a player would draw from it, the game ends immediately. The player with the most points wins.
Q: Do I draw Rations cards from the supply or from my hand?
A: From the supply (the shared pool of Ration cards). The supply is not defined in the rulebook; we recommend adding a definition in the Setup section.
7. Suggested Rewrite Lines
For the passages we judge worst.
Page 2, Setup: Replace “Each player starts with 5 Rations cards.” with “Each player draws 5 Ration cards from the supply. (The supply is the shared pool of all Ration cards not in any player’s hand.)”
Page 3, Card Types: Replace “You may only play one Ingredient card per turn.” with “You may only play one Ingredient card per turn, except during the Cooking Phase, when you may play any number.”
Page 6, End of Game: Replace the two conflicting sentences with a single win condition: “The game ends when the last Recipe card is claimed. The player with the most points (each Recipe card is worth 2 points) wins. If tied, the player with the most Ingredient cards in their scoring area wins.”
Coverage Checklist
Each domain examined and its result.
- Timing and priority: Checked. One simultaneous-trigger case flagged (Finding 3.1).
- Ties: Checked. No tiebreaker defined for the point-based win condition (covered in Finding 1.3 and suggested rewrite).
- Empty deck/supply: Checked. Recipe deck empty not addressed (Finding 3.2).
- Simultaneous triggers: Checked. One case flagged.
- End-game trigger conflicts: Checked. Two conflicting end conditions (Finding 1.3 and Finding 3.3).
- Illegal-move recovery: Checked. One case flagged (Finding 3.4).
- Component cross-check: Checked. One mismatch found (Finding 4).
- Iconography: No icon key provided; skipped.
- Board layout: No board provided; skipped.
Report summary: 3 contradictions, 11 undefined/inconsistent terms, 4 unresolved edge cases, 1 component mismatch, 1 teach-order issue. This is a relatively clean manuscript for a first draft. The contradictions and undefined terms are concentrated in the end-game and Cooking Phase sections. Addressing the suggested rewrites and FAQ entries will resolve most issues before playtesting.
