Pick a category. Every game is a fresh board.
Tap a letter to get a question. The answer starts with that letter.
Drag across the dial to spell it. The first letter of each word is shown faintly as a hint, but you still spell the whole word. Points fall from 1,000 to zero over 30 seconds.
Finish a row, column or the diagonal with every answer right to win the bonus at its end: 500 to 2,000 points or a power-up. Bonuses move every game.
