Seal of Leviathan is a puzzle in Professor Layton vs. Phoenix Wright: Ace Attorney. The puzzle must be solved in order to progress the story.


There are three large platforms leading across the river. Each platform is being weighed down by large pieces of stone.

Moving a stone block on to a platform will add additional weight and cause it to lower. Likewise, removing a stone block will cause the platform to rise.

Use all the stone blocks to lower or raise the platforms so that they are an even height.


Click a Tab to reveal the Hint.

Begin by trying out all of the blocks and gauging their weight.

Every platform must have at least one block.

The platform in the middle should contain the most blocks. Three, to be exact.

The right platform should only contain one block; therefore, the left platform should contain two.

The right platform should only have the smallest block, and the platform on the left should have the largest block and the medium-sized block.

Which blocks should be placed on the middle platform?




That's one seal cleared!
Now the real challenge begins...
