Tetris blocks rules

[Snake]

So, I went down to the swamp, did the very basic tetris tutorials, moved the platform to the other end where the red grids show up and can't do the first one.

From what I understand, tetris blocks you draw can share the same enclosure, as long as the volume / number of blocks is right, they cannot be rotated and they cannot overlap / share the same block.

Even with all that in mind, I can't do this one:

Any hints, am I missing any rules?

[Curious Duck]

You can move them around as long as the shapes are inside the area you cut off.

Imagine the space you need to form if they were all touching, but not overlapping.

[Snake]

Oh, Jesus, so I don't need to include the spot they are drawn on the grid in the solution? :D

[james.world]

Yes you do need to include the spot the shapes appear on. The rule is: If any shapes fall inside an area bounded by a solution path then it must be possible to arrange those shapes in a non-overlapping manner such that all squares of the bounded area are covered. Note: A shape can be moved to any square in the bounded area; it is tied to the *bounded area* not the square where it appears. Furthermore, if the shape appears off-axis (rotated) it can be rotated in the solution, if it doesn't appear off-axis it must be used in the orientation shown.

[Snake]

Yeah I read somewhere about the rotated blocks. But given those rules, I still don't see how I can draw an enclosure containing the horizontal 4-piece AND the vertical 3-pieces without overlap, and still make it to the exit.

[james.world]

Imagine the horizontal block on the bottom, and the other two next to each other above it on the left side.

The mental gymnastics of those puzzles can be tricky! :D

[Snake]

But the horizontal at the bottom DOES involve fitting the solution-shape in an area that does NOT include the square the shape shows in the grid...

[james.world]

As I said above, the tile is tied to the *bounded area* not the square where it's symbol appears. The *bounded area* in this solution encompasses the bottom row and the two left columns. The shape symbol is in the left column. So it's included - in the bounded area - because you can traverse from the symbol to the shape without crossing a solution path.

Solution exactly: R,R,R,R,U,L,L,U,U,U,R,R

[Tachrayonic]

Where you put tetris piece does not need to overlap it's icon, but the enclosure that the piece is in must contain excactly enough room for all tetris pieces with icons within.

So, you can put the 4-long along the bottom, as long as it is connected to it's icon by one of the 3-longs.

[Snake]

Riiight, riiiight, damn Blow was right, it's hard to verbalize this! :D

So, as long as all the icons are all within the encompassed area, it's all good - they don't need to be specifically in THEIR OWN shape as part of the solution. Back to it then! :D

Thanks, folks!

Bumping to avoid making a new thread as it's still tetris rules.

I got to the rotating blocks, did the very first two tutorials and got stuck on the third one with the two Г shapes.

I'm not sure I understand the difference between the symbol slant variations. The original two had a VERY right-slanted symbol and in those I'm doing rotation to the left / counter-clockwise.

The one that stumps me with the two Г-s has a LIGHT left slant on both symbols. I tried testing the rule and it accepts the right symbol with the beak pointing down.

Now, I don't think the grid coulд physically fit both Г-s with the beak pointing down like that ¬

Is there an extra rule I'm missing? Is the slant just indication of rotation direction or does one of those mean "rotation optional"?

[The Renderer]

As far as I know there is no "rotating direction", you can rotate as much or as little as you want. Your description is hard to understand, though, maybe you have a screenshot of the puzzle in question?

[Snake]

For both slants of the icons?

[The Renderer]

Now you are making me question my beliefs. I don't think the slant matters. Never occured to me, though, so maybe I'm missing something as well?

[Snake]

No freaking idea. I'm only at the tutorial. Switched up to some older, non-rotational ones. Is there a hidden rule here?

No, just outline the blocks, just don't start straight up but one step to the right.
