The Vocabulary Quiz is a deterministic five-round definition-matching game where each round displays one English word and four candidate meanings, and a fully correct run always scores exactly 1,000 points (200 per round). The format is intentionally short: there are no timers, no accounts, and no upload step, because the entire session runs locally in the browser as a client-side game. Every round begins at the middle of three difficulty bands, and the band shifts after each pick rather than after the whole session. A correct selection moves the next round one band higher, up to a challenge ceiling; a wrong selection moves the current band one step lower, down to a foundation floor, and replaces the four candidate meanings immediately. The session length is fixed at five rounds, so the result is a brief recreational score rather than a long assessment.
What the Vocabulary Quiz Shows Each Round
The visible board is deliberately minimal. One English word sits at the top of the round, and four candidate meanings are rendered as plain, readable text below it. There is no color-coding that identifies the correct answer, no hidden solution in the markup, and no answer-key element inserted into the page after a guess. The four candidate buttons use neutral test identifiers and repeat their visible option number in the aria label, so a screen reader announces the same content a sighted user sees. Because the correct definition is not always in the same position, the round forces you to read each candidate rather than guess a slot. Across the deterministic winning route, the correct choice appears in four different button positions, which guards against position guessing and makes the player read the text. Every candidate is rendered as ordinary visible content, so color alone never communicates its identity. The shared GameShell also surfaces the running score, the local best-score memory, a Restart button, and a Boss Key that quickly hides the game during a shared screen.
How the Adaptive Difficulty Bands Work
The vocabulary quiz runs on three difficulty bands, and your current band changes after each pick rather than after the whole session. The session always starts in the middle band. A correct choice raises the next round one band higher, up to a challenge ceiling. A wrong choice lowers the current band one step lower, down to a foundation floor, and the four visible candidates change immediately to an easier set. The adaptation changes the question experience rather than merely changing a label, and easier sets use more clearly separated distractors while harder sets place more closely related adjective senses beside the target meaning.
| Band | Position | Distractor Quality | When You Reach It |
|---|---|---|---|
| Foundation floor | Lower band | More clearly separated distractors | After a wrong answer, when already low |
| Middle band | Starting band | Mixed separation | First round of every session |
| Challenge ceiling | Upper band | Closely related adjective senses next to the target meaning | After a run of correct answers |
Difficulty affects which candidates appear, not the reward. Every correct round is still worth 200 points no matter which band is active, and the underlying prompt stays stable during a wrong-answer adjustment so you can study the easier contrast before trying again.
Play the Vocabulary Quiz Step by Step
To run a clean five-round session, open the Vocabulary Quiz page and work through the rounds in order.
- Read the visible word at the top of the round and skim all four candidate meanings before picking, since the correct definition does not always sit in the same slot.
- Choose the candidate whose definition matches the word most closely, using either a mouse click, a tap on a large definition button, or Tab plus Enter or Space on a keyboard.
- Watch the immediate response: a correct selection raises the difficulty band for the next round and adds 200 points; a wrong selection lowers the current band, swaps the four candidates for an easier set, and records one miss.
- If you recorded one miss on the current prompt, you can still finish the round by picking the correct meaning next and earn the full 200 points for that round.
- Repeat until you have completed five rounds with one correct meaning each. A clean five-round run totals exactly 1,000 points, while a second distinct wrong definition locks the session and forces a Restart.
How Wrong Submissions Are Tracked and Deduped
The miss counter is built on normalized signatures. Before a wrong submission is counted, the candidate text is trimmed, converted to lowercase, and any internal whitespace is collapsed. Submitting the same wrong definition twice, even with different capital letters or extra spaces, deduplicates against the first miss and does not consume a second one. A second distinct visible wrong definition, however, sets a deadlocked state. Once that lock triggers, all four candidate buttons are disabled and every later input becomes an atomic no-op. Inputs outside the four currently visible definitions are also ignored atomically, so empty values, non-string values, and stale definitions from a different difficulty set cannot alter the board, the score, the difficulty, the message, or the attempt count. The completed state is protected by the same boundary, which keeps the maximum easy to audit. Restart then restores the exact starting round, the middle difficulty, an empty attempt set, zero score, and an unchanged deterministic candidate order.
Scoring Math and the Perfect 1,000-Point Run
The scoring formula is the simplest part of the game. Every correct round awards exactly 200 points, regardless of difficulty. A clean five-round path therefore produces:
5 correct rounds × 200 points per round = 1,000 points
That is the only way to reach 1,000, because difficulty controls which candidates appear, not the reward. A wrong choice before the final correct pick does not reduce the 200-point reward for that round, since you can still finish the same round after one miss and still collect the full 200 points. The lock rule, however, prevents you from collecting more than one corrective round if you pick two different wrong candidates, so the lock caps how far a single round can recover.
Keyboard, Touch, and Accessibility Details
The vocabulary quiz is built for keyboard-only play. Native buttons support Tab to move focus, and Enter or Space to confirm a selection, so a player can complete a session without a mouse or touchscreen. Every definition button has at least a 44-pixel interaction height, which keeps the round touch-friendly on small screens. The layout also includes minimum-zero grid tracks, wrapping definition text, breaking feedback, and an overflow guard so the two-column desktop design does not introduce horizontal overflow on a 390-pixel phone. Because the game runs locally in the browser as a client-side L1 game, no choices, difficulty changes, misses, or scores are uploaded for grading, and no account is required to play. The shared GameShell supplies the running score, the local best-score memory, the Restart button, and the Boss Key alongside the round itself.
What the Result Band Means and What It Does Not
The final label is intentionally scoped as a recreational session band. It is explicitly not a diagnostic, certification, standardized assessment, proficiency decision, educational placement tool, or real vocabulary-size estimate, because five fixed items cannot support those claims. The band only summarizes what happened in this brief game session and should not be used to make decisions about a person. The eight spellings and displayed adjective senses are audited reference data drawn from the Princeton WordNet 3.1 adjective index and the Cambridge Dictionary, which keeps the answer key auditable without exposing it in the page before grading.
