- Goal
- A pen falls when its middle goes past the desk edge. Knock every opposing pen off while keeping yours on.
- Your turn
- Flick one of your glowing pens. Tap a pen or its tag to switch.
- Flick by hand
- Press on your pen where you want to hit it, pull back like a slingshot, and let go. Pull further for more power.
- Fine-tune
- The ruler sets where you hit: near the middle sends the pen straight, near an end makes it spin. The protractor sets the direction, and Power sets the speed.
- Hop
- Drag the pencil knob above your pen upward to raise the dotted hop arc, or down to flatten it, or use the Lift slider in the tray, then flick. Hop over a pen, land on the notebook or geometry box, or drop onto an opponent.
- Clutter
- Notebooks, erasers, the geometry box and the sharpener slide and spin when hit, and fall off the edge too. An eraser skids away; the geometry box barely budges. Pens resting on top ride along.
- Camera
- Drag an empty spot to look around. Pinch or scroll to zoom. Use two fingers or right-drag to pan. Side, Top and Pen jump to preset views.
