Sure, any objects could be used as walls for Dungeon Drop. But if you're already buying the mats, an extra $5 is cheap for nice walls that match.

Very satisfied. Thx

Just a fun and simple game for everyone to enjoy and the deluxe version with added faces makes it adorable and easier to spot the enemies. Would recommend for a simple fun game night.

Keeps everything in order, and I recommend trying not to over organized with more trays and leave the walls and mats in the box.

It helps minimize the bounce from the cubes and with the walls. They are extremely helpful to keep the cubes from falling off the table.

I still gave it five stars because I didn't need the drop drive items, but still glad I got it for dungeon drop.

Adds more to the game and makes it a lot more fun to play.

It's a nice bag to use for mixing and dropping the cubes.

Got this for emergency to keep my cubes in order and use like a player cube holder when in play.

Adds to the game and have a metal piece is always awesome in my book.

It is a string that helps with game when you need to be little precise.

These are firm enough to withstand the impact of the pieces bouncing against them, and as a result they are a must-have. I just wish these folded into fourths accordion style so that I could possibly fit these inside the box somehow.

The game fits perfectly with the branded sleeves into the box. The whole gimmick of an engine builder with temporary parts that can help you go off when they expire is really interesting, and I love its execution here!

Haven't used this expansion yet, but cards and peices are the same high quality as the base game.
