The gold is mine!

If you enter the ramp to Treasure Chest with enough speed, the ball will knock the lock of the Treasure Chest open for a bonus of about 400,000 points. Lighting the three drop-down targets just above the Whirlpool activates an accelerator that gives you extra speed up the ramp. Lighting up the Deep Dockyards will multiply your score by up to 2.5 times.
