Gather round the board. Flick marbles into the rings, knock rivals into the hole, and impress the cats.
Drag back from your marble and let go to flick it. When everything stops, marbles in the rings score 1, 3 and 5. Sinking a rival's marble in the centre hole earns +3. Anything that rolls off the edge is gone, and a marble left sitting on a launch pad is swatted off the board by an irritated paw, costing the shooter 2. The four hotspots on the edges swallow any marble that rolls slowly across them and set something off: a catquake, a fit of the zoomies, a paw that reaches out of the hole and helps itself, or a cat who strolls on and bats a marble away. Handy when you're losing. Each one needs a full round to recharge, and after every event the hotspots shuffle places. Every third marble is a giant: heavy enough to bulldoze, too big for the hole, and it shrinks back once everything stops. Tap a seat to switch it between player, computer and empty.
The marbles will wait.
The cats might not.
