I've taken a bit of a break from dungeon terrain with my latest video ...and instead I've had a go at making a puzzle piece that your players can get their grubby hands on :)
Now, the puzzle itself isn't much more that a crossword puzzle (albeit one where the players already have all the letters they'll need), and it's a simple matter of inserting the letters into the correct slots to spell out the answers to the four riddles.
So the answer to 'I have no wings, and yet I fly." goes along the top (and is 5 letters long) for example.
From there the answer to each riddle goes around in a clockwise direction (so riddle two's answer goes on the right, riddle threes' answer goes along the bottom), and once all of the letters have been correctly placed, the door unlocks (or the chest opens, the trap is disarmed, or whatever).
As usual, I've made a short video showing how easy it is to put together...
...and the pdf file can be found on DriveThruRPG (it's pay-what-you-want so feel free to pay as much or as little as you like).
Anyway, I hope you like it ...and I hope you'll be able to find a use for it in your games!
