I'm not sure why this is wrong. Could someone explain it to me?

Keep Tower Incorrect

  • One of the L shapes you've accounted for is backwards.

    @Vemonus how so? all 3 of them would be correct if they can be rotated (the middle one is 180 degrees rotated of the top one, the bottom one 90 degrees counter-clockwise of the middle)

    The top left is correct, but the one directly attached to it. That one is backwards. All of the shapes you're given are backwards Ls, but that one accounts for a forwards L.

    The straight 4 is wrong, see related question: gaming.stackexchange.com/questions/255540/…

The section with the tetris-pieces is incorrect. That would only work if the straight-piece could be rotated (it can't) or if the backwards-L-shapes could be mirrored (they can't)

  • This solution doesn't require mirroring of the L shapes, they are all backwards Ls.

    @Austin: Yes, it does require either mirroring one of the L's, or rotating the straight-piece. Unless your point was just to be pedantic about the piece-names, in which case, I'll update the answer... Mar 22 '17 at 6:14

    Sorry, I read your statement as 'and', and didn't notice the arrangement that needs forwards L.
