You take it in turns with your opponent to place words on the game board.
You win words by answering questions correctly.

Choosing whether or not to answer another question depends on your assessment of the strategic value of the correct answer to a question.
If you get a question wrong, you lose strategic control.
You don't get to choose which words can be played on the board.
You don't get to choose whether words have high or low scoring potential.
If it's your turn, you have to play words you don't know.
If it's not your turn, your opponent plays the words you don't know...and that's risky because Dr A.I.N. Stein is wicked smart!
