    Even with the video sideways and otherwise mediocre in quality, it was exciting to watch three of the world’s best puzzle-solvers tackle this Pentominous live. I hope that the readers of this site get to see my other WPC contributions soon!

    Is it possible to construct puzzles using an 8 by 8 grid plus a 2 by 2 square in the middle say that would use all 12 pentominoes only once?

    It is known that it is possible to tile an 8×8 grid with a 2×2 square hole anywhere (not just in the center) with all 12 pentominoes. Any such tiling can be the solution to a trivial Pentominous by specifying all 60 letter clues.
