How do you beat the Viking cave on Time Tangled Island?

Answer 1

Timing is critical to reach the treasure at the bottom of the cave. Your torch begins to go out as soon as you enter. Jump down and to the right, and keep going higher as you move right. Once you pass the center divider, jump down all the way to the bottom and go left. You will have to jump three pools of water at the end (if you can't see clearly, just jump three times left at the first pool). (see related questions)

Answer 2

Get the Thor Amulet and Gunpowder from the Great Wall of China

The Vikings (2 o'clock, 831 AD) are stranded because they've lost their Thor's Hammer amulet. Go to the Great Wall of China (6 o'clock, 1593 AD). The amulet is at the top right (watch the falling bricks!), where you will play a challenge game. While there, go to the bottom right and get the barrel of gunpowder. You will need it to blast the rocks at the Vikings site (to recover the Greek vase hidden in the cave).

When you reach the rockpile on the hill, click on it to set off the gunpowder. You will enter the cave with a wooden torch, which will rapidly burn out. You must quickly locate the vase. Go down, up, up, up, across, down , and left, jumping three puddles of water at the end. The Golden Vase is for 328 BC (1 o'clock on the time device).
