I just wondering if you have a way to complete the task of "Tiling a 10x10 grid with tetrominos". I know this has been done before, but I was wondering if there are other methods?

Best regards Synne (Norway)

  • $\begingroup$ They probably meant to ask about tiling a $10\times10$ square with T-tetrominoes, in which case the question is a duplicate. $\endgroup$ Nov 7, 2018 at 5:19

1 Answer 1


Use 5 2x2 tetrominoes to cover a 10x2 area, then use 20 1x4s to create 10 1x8 pieces, each covering one remaining row.
