Vocabulary

Vocabulary turns vocabulary review into tic-tac-toe: a board of numbered squares, each hiding a word to match with its definition. You don't fill the whole board; you win by completing a row, a column, or a diagonal. The board can be chosen as 3×3, 4×4, or 5×5, and everyone receives the same grid for a given date and size.

1. Choose the board size (3×3, 4×4, or 5×5), then launch the day's grid.
2. Click a numbered square to open the question it hides.
3. Match the given word with its definition before the timer for that square expires.
4. Chain squares together aiming to complete a row, a column, or a diagonal, the condition for victory.

The design trick lies in the uneven timer from one square to another: the board is not just a list of questions, it's a map of risks where the winning alignment is negotiated against time. The format suits short revision well, which the page assumes by addressing students and candidates preparing for exams.

A square's color says two successive things. Before an answer, it indicates the time allowed: blue for thirty seconds, yellow for twenty, red for ten, white for a square without a timer. After an answer or expiration, it switches to a third set of colors, Correct, Incorrect, or Timeout, which fixes the square's outcome.

3×3 Board

The short format offered by default on the day's page.

4×4 Board

Intermediate grid, same rule of row, column, or diagonal.

5×5 Board

The largest format offered, with more questions in a single session.

• Check a square's color before opening it: a red square gives only ten seconds, a white square lets you think.
• Plot your line in advance rather than opening the squares in order, victory comes from an alignment, not from a perfect score.
• Save the slow or untimed squares for the end of the alignment, when the pressure is highest.
