The idea of using a dice tower to roll dice might make some upset, confused, or consider it blasphemy. I have never used a dice tower myself until playing Wingspan. I'm am also staunchly against inserts. I just don't like the idea. Don't get me wrong; I still organize them. I just do it my way. I only give you this information so that you can firmly understand my experience.
I recently purchased my first dice towers ever from Broken Token, and the Sagrada dice tower was among them. Lets go over this as a total newb to constructing any sort of Broken Token product.
When the packaging arrived, I was nervous about how these small "sheets" of wood could turn into a tower. They have videos on YouTube and on their site, and this can give you confidence to tackle the project. I however was a huge fan of Legos growing up, so the instructions read just like a Lego creation. No issues on excellent instructions.
My real first hurdle was to remove the pieces from the sheet of wood. I've never really ever dealt with wood, much less such thin and precise pieces. After seeing that the pieces are cut so that it's actually just barely hanging on by a thread of wood, I grabbed some spare sanding paper to smooth out those odd hanging "Chads".
Once I began to assemble the tower a few things became apparent. The use of glue, which I had on the ready, was absolutely unnecessary. The pieces fit like the aforementioned Legos pieces. You don't have to have a high dexterity score, but it helps. I was legit surprised at how they just snap into place. The hobby hammer/mallet can help, but it doesn't take much to get them locked in.
So now that it's assembled, it's AMAZING. It comes with it's on dice tray, which you can use, or use the one from the 5-6 expansion if you've got that. In fact, if you've got players that aren't going to use the tower, having two trays is a plus. The front of the tower has a slot for the little color scoring markers. Those might as well just live there now because it's adds an incredible atmosphere to the game. I am not a painting guy, but I know some of you are. This thing is begged to be painted!
The theme of the game, plus the actual nature of the cathedral you are building, the practical use of the dice tower, the visual aid of adding paint/color to it or not ( I like the natural look), this was an incredible addition to the game.
