How am I supposed to find puzzle boxes?

I've opened 550 chests in 43 floors and have only ever seen 2 puzzle boxes to even attempt. By extrapolating that, I won't be seeing all 50 puzzle boxes until floor 1075. That seems excessive, so clearly I'm missing something. Are puzzle box appearances not random?

1 Answer

The puzzle box appearances are random. But, you may be missing some things:

For a puzzle box to appear, a mii has to:

• Own the game regardless of tags, or
• Have two or more tags

Note:

• A Game owner mii gives you puzzle boxes its already completed.
• A Non Game Owner 2+ tag mii guarantees you a new puzzle box.

To receive a puzzle box from miis, you have to:

• Already set the mii's piece, and
• Make a 2x2 room or bigger in the same session
