Great tile set! I use them a lot in my games. Many pieces with endless dungeon making possibilities. You do wanna make sure to have a non slick surface under the tiles or them will move around. I flip one of my rubber game mats over and it works. Some times ill but a clear plastic board on top to hold everything in place. That's mainly if its a large dungeon and I want to have it all ready to go before my group comes over.
