# Clue Fall

`clue-fall` is a progressive shared-screen guessing game. Five clues describe one answer, but the available score falls from five points to one as each new clue appears.

## How to play

Open `/clue-fall/` on a TV, projector, laptop, or large display. Players scan the standard room QR code to open `/clue-fall-c/`, choose a screen name, and select **Easy**, **Medium** or **Hard** from the display or any joined controller.

**Easy** is aimed at children, with 40 familiar puzzles, four answer choices and 15 seconds per clue. **Medium** has 30 puzzles, five choices and 12 seconds. **Hard** has 30 expert puzzles, six choices and 10 seconds. The hardest clue appears first and is worth **5 points**, reducing to 4, 3, 2 and finally 1 point.

- Tap the correct answer to bank the current points and finish that puzzle.
- A wrong answer is removed from your phone and locks guessing until the next clue.
- Each player receives their answers in a different order.
- If every active player has guessed or solved, the next clue arrives early to keep the game moving.
- The display reveals the answer and a short bonus fact after every puzzle.

The game includes **100 hand-written puzzles and 500 progressive clues** across ten balanced categories: Movies, Famous Faces, Around the World, Science & Nature, History, Books & Characters, Music, Sport, Food & Drink, and Things & Technology. Easy contains three non-repeating rounds of 15, 15 and 10 puzzles; Medium and Hard each contain two rounds of 15. Scores carry through the selected mode, and a new series reshuffles that mode's puzzles.

## RCWeb design

The viewer owns the clue timer, answer validation, eliminations, scoring, puzzle order, and leaderboard. Controllers send join, start, and guess intents with `rc.sendFunctionCall`, then receive player-specific snapshots. Player identities are saved locally so reconnecting phones recover their score, eliminated answers, and current clue.

The viewer includes the standard RCWeb room QR panel plus a QR modal for narrow portrait screens. Its responsive layout supports 1920x1080 and 960x540 landscape displays as well as 1080x1920 and 450x960 portrait displays. A lean-paint mode removes gradients, shadows, and animations on older Tizen displays or when `?lean=1` is present.
