## What is Lantern Clause?

Lantern Clause is a portrait puzzle game built around Rule Card Deduction. Every case hides a rule that connects playing-card ranks, suits, positions, and neighboring evidence. Flip witness cards, spend Lantern Oil, and use the Deduction Ledger to test constraints, expose contradictions, and reconstruct the hidden rule before naming a suspect.

Explore a bright paper-lantern town through 24 story cases, daily fixed-rule puzzles, deduction endgames, and limited-flip Cold Files. Follow clues in character conversations, record your assumptions, and add keepsakes to Lantern Square as your understanding of the town grows.

Each witness card states a small, specific condition: a rank higher than the marked card, a suit shared with the account on your left, or a location outside the east wing. These statements form a solvable card-logic language. The Ledger lets you compare every assumption with the evidence, so a conclusion can be checked instead of guessed.

Rule Card Deduction is the core of every mode. The hidden rule changes how rank, suit, position, and neighboring cards interact, and the correct sequence of investigations matters as much as the final answer.

Features:
- Rule Card Deduction: reconstruct one hidden rule per case
- 24 story cases across four lantern districts
- Daily fixed-rule cases and stand-alone logic puzzles
- A compact Lantern Oil economy tied to evidence choices
- Career records, achievements, character notes, and town keepsakes
- Fully offline, portrait-first play for iPhone and iPad

No ads, no in-app purchases, no random card draws, and no gambling. Lantern Clause is a warm, hand-crafted card mystery about reading the evidence in front of you.

## Version history (last 3 releases)

### 1.0.2 — 2026-10-27

• Evidence has been rebuilt around structured clues. The Ledger now tracks how many Rule Cards remain possible and updates the count as you investigate.

• Witness cards now show their evidence type and time before they are opened, helping you decide whether to investigate rank, suit, district, or testimony evidence.

• Clues now provide partial constraints that must be combined. Pass or fail testimony tests help eliminate Rule Card candidates without revealing the answer outright.

• District seals stay hidden until the Rule Card is isolated, so the board no longer gives away the rule's district at the start of a case.

• Three-star reveal targets now adapt to each case's evidence path.

### 1.0.1 — 2026-10-24

Improved deduction feedback, case scoring, and testimony reliability.

The Deduction Ledger now separates candidate testimony from excluded cards and clearly flags when a Rule Card is not unique. Star ratings now reward efficient investigations that conserve Lantern Oil and avoid failed accusations. Unreliable testimony is marked by a visible torn seal across the board, reveal notices, evidence details, and the Ledger.

### 1.0 — 2026-10-22

No release notes.
