In Is this Tetris puzzle solvable? we established that it is not possible to form a rectangle with an uneven number of each Tetris piece.

But if we had a solution for 2 of each piece, we would now that it works with any even number of each piece, because we could just stack the 2 of each solution.

Question: Is it possible to form a rectangle with 2 of each Tetris piece and if yes what would your solution look like?

  • $\begingroup$ Don't worry, I don't mind! Not my kind of problem anyway. If I was going to try it, though, I wouldn't cheat! :-) $\endgroup$ – Rand al'Thor Aug 15 '15 at 16:04

  • $\begingroup$ @Deusovi I actually don't know whether we have a policy for that. Anyway, the downvotes suggest that the community doesn't like it, so I've removed that sentence. $\endgroup$ – Sumyrda - remember Monica Aug 15 '15 at 17:41

I'm not sure what size box you want them packed in, but based on the 7-wide in your other question, there is this option:

7x8 Grid

    $\begingroup$ I like this solution because it can be easily rearranged into a 4x14 by just splitting across the middle. $\endgroup$ – Deusovi Aug 16 '15 at 3:45
