If you are new at LMI, here is the link to Fillomino Fillia (1), which was a hugely appreciated test here.

I think you have the month wrong

And in no-rectangles, are squares counted as rectangles? Like a 1 cell or a 2x2 of 4s?

Those configurations are not allowed, because by definition, a square is a type of rectangle.

Just to confirm in SNAKE FILLOMINO,
Is there a possibility of snake dividing the grid into two parts. I mean head in the last column and tail in 1st column and they are connected from middle of the grid, so the grid is divided into two parts.
Another way of saying is all polyominoes need to be connected ??

I think the only difference is the path can touch itself at a point, but the Snake can't.

Fillomino Path and Fillomino Snake are different variations. The example in the IB is not unique if solved as Path due to the lower left.

There is no condition that the other polyominoes need to be connected in Snake. You should treat the Snake as just another polyomino in the grid, with the one exception that it is allowed to touch a polyomino of the same size as itself.

EDIT: tamz's question can also be answered by realizing the example is not unique without treating squares as rectangles. If you have any confusion about the rules you might try proving the example's uniqueness and see which set of rules works before asking.

Can't the snake not touch itself either?

Brian Pwnox asked on Google, "for the snake, can the head hit the tail?"The snake may not touch itself, even diagonally, in any fashion. Precisely:No two orthogonally adjacent cells may both be in the snake unless they are adjacent in the snake's path.No two diagonally adjacent cells may both be in the snake unless another snake cell shares an edge with both.For the purposes of the crossover with Fillomino, the snake functions as any other polyomino, with the exception that its size doesn't care about the "no two polyominoes of the same size may share an edge" rule.I really hope this clarifies every question anyone could ever ask about Snake Fillomino.

For the no rectangles variant:
Is it "no individual polyomino can BE a rectangle (including squares)" or "no combination of polyominos can form a rectangle"?
The phrasing is a bit ambiguous to me. Of course for the latter, you'd have to except the fact that ALL the polyominos form a rectangle together.

These are all worthy of being in a contest set themselves, my favorite so far is definitely the No Rectangles.

A quick note about penalties: as the IB says, we doubt there will be any manual answer entry correction on this test. In particular, the penalty will stand if the solver is at all at fault for the wrong answer, even if it's a simple typo or a right answer submitted for the wrong puzzle. Please keep this in mind as you take the test and check for stupid things like that.

In addition to the Preview series from the two test authors above, there's also a Liar Fillomino by Para that can be used for practice -

Is the snake allowed to have length one? I'm just wondering because one of the puzzles I created (which was mostly a joke) would have multiple solutions if this were allowed. I hope that the snakes will have length more than one on the test :)

Don't think we ever really decided if there is such a length restriction. That will be a nonissue on the test.

The snake has "a head and a tail". Technically it would be of length at least 2. But I'm sure the authors won't make such joke puzzles ( http://kitkatksun48.wordpress.com/2012/10/22/fillomino-snake/ ) :P
