Twin Snakes

Rules:

The left side is Chaos Construction while right side is Fillomino Snakes.

Chaos Construction: Divide the grid into six orthogonally-connected regions, each containing six cells. Each row, column and region must contain the numbers 1 to 6, once each.

Fillomino Snakes: Divide the grid into regions of orthogonally connected cells. Each cell should contain a number equal to the size of its region (i.e. the number of cells in its region). Furthermore every region is a snake a one-cell wide path of orthogonally-connected cells that does not branch or touch itself orthogonally.

Zipper line: Numbers an equal distance from the center of the purple line must sum to the number in the center of that purple line. Furthermore, for each grid the cells on the zipper line contain different numbers and are on different regions.

Same positions: Same positions on different grids can't contain the same numbers. Eg: the top left cell of both grids can't contain the same number.

Dominos: Numbers separated by an X sum to 10. Numbers separated by a black dot must be in ratio 1:2. Not all Xs or dots are necessarily given.

Except the center of zipper line other cells outside the grids don't contain numbers.
