Apostrophe Placement ("Tetris" Game)

Here is an interactive game to help you learn the apostrophe-placement rules.

• Each falling question has a correct possessive apostrophe and a wrong one.
• Click on the correct one to score points and to make the question disappear.
• If you click on the wrong one (or do not click), the question will fall to the bottom.
• The wrongly answered or unanswered questions will start to build up.
• When the screen is full, you're toast.
• Good luck!

(The harder the level, the more points you score per correct answer.)

Tip: If the game is playing slowly, you can use the controls below to remove the background text and image to speed up the game.
