Puzzle 91: Margin of Error
Heteromino

Oh yay I’m alive.

There we go. Recently I got the inspiration of Heteromino with a two-cell wide empty border. A 10×10 doesn’t seem to work, since I only have 6×6 space to work with the black cells, but a 14×14 looks good. Besides, I can say “here’s the 10×10 puzzle, and in case you need it, here’s two-cell margin of error around the grid if you’re stuck or something”.

…yes, I appear to be terribly uninspired for titling puzzles.

Also, I appear to start playing Pokémon Trading Card Game Online. It’s free to play, although getting the in-game currency to get more cards might be a little hard.
