Answer a series of quick-fire quiz questions whilst perched perilously on the seat of a high-speed rollercoa...  (plus)ster. As your carriage travels over the twisting tracks, quiz questions will appear. Press the key that corresponds to the correct answer before time runs out! To make matters a tad more tricky, a bucket of sick is balanced on your lap! As the coaster twists and turns, the bucket will sway and spill. If you see it lean to the right, move your mouse to the left to straighten it up. If you see it lean leftwards, move your mouse to the right to restore the balance. Don't let it spill - you lose points for each superfluous splash!  (moins)
