Reveal — Hidden Phrase Board

A “guess the phrase” marquee: a key term hides behind blank tiles and the host flips letters into view a few at a time while teams race to call the whole phrase. A value ladder drops as more letters light up, so solving early is worth the most; a wrong solve locks that team out for the round. Team mode keeps score and rules each buzz; solo mode is a self-paced reveal-and-learn. Ships as a blank, commented template.

Problem
Pure question-and-answer review misses pattern recall — and rarely builds the room-wide tension that makes a key term actually stick.
Who it helps
Facilitators reviewing terminology and key phrases — two teams racing on a projector, or one learner revealing at their own pace.
In training
Reveal letters from the keypad while teams watch the value drop, hit a team’s Solve button when they buzz, and rule it right or wrong; the longer the board stays dark, the bigger the score.
Skills shown
Front-end build, reveal-and-score logic, value-ladder design, lock-out handling, projector-first UI, trainer-editable template.

How to edit

  1. Right-click the file → “Open with” → a text editor.
  2. Scroll to the banner ★ EDIT YOUR GAME HERE ★ near the top of the script.
  3. Edit PHRASES — each is a { phrase, clue } pair (letters A–Z; spaces split words).
  4. Optionally tune START_VALUE, DROP_PER_REVEAL, and MIN_VALUE to set how fast the score falls as letters show. Save, then open in a browser.
