Extinction Event

You are the asteroid: aim one impact, trigger a planet-wide chain reaction, erase the dinosaurs—and somehow save the mammals.

Pick a target tile and a shot, press Launch, then watch the Shockwave, Wildfire and Tsunami reach what the crater alone could not. A run succeeds only when every dinosaur is gone and at least one mammal is still alive, because those mammals are the Future. Each run ends with a very official Extinction Report that shows what happened and why. Retry restores the board and your last shot instantly.

Twenty-five campaign sites ask new questions of one simple shot and end in a promotion. Sixteen Bonus Sites follow, with lake surges and a rock that splits. Three stars per site. Play in a browser with mouse, touch or keyboard.

Controls: click or tap a tile to aim, then press Launch. Later sites add Size and Approach buttons. Keyboard: arrow keys move the target, W/S change Size, A/D change Approach, Space launches, R retries, P or Esc pauses and H opens Help. Menus use arrow keys and Enter.

Accessibility: No timed aiming or required dragging. Large text and high-contrast hazard markers. Reduced motion and reduced-flash options. Sound captions and full play with audio muted. Pause during every live phase. Landscape play; rotate or enlarge smaller views.
