Think 'Hungry Hungry Hippos' with extra stuff.4 players' marbles are dumped into a hopper. Each player pushes a button as fast as they can to fill a channel with 5 marbles. They can take the marbles of their own color to put in their tray, which is cat-shaped. Then, dump the other marbles back into the hopper and keep pressing. Fill your tray with your own marbles (plus the 'cat's eye') and win. - BoardGameGeek
