Does filling up the game board reduce the obstacle generation rate?

I've spaced out the buildings on my base so that there is no open area to spawn troops on the playing field. All of the buildings are once space in from the edge so that all of the obstacles will spawn on the border. I still get some obstacles spawning on the border but it seems like they are spawning at a slower rate now. According to the CoC wiki they are supposed to spawn about every 8 hours. I haven't actually timed it yet so it could just be my imagination, going to start doing that now.

Could part of the problem be that there is no place for a 3x3 obstacle to spawn?

I have the same problem. I have plenty of spaces for 2x2 obstacles, but they are spawning so slowly

i believe it's every 8 hours an obstacle will TRY to spawn. if there is a building in the spot where it tried to spawn, then nothing happens. it will try again in 8 hours in a different spot. in your example, supercell probably tried to spawn one in the middle of your base but it was occupied by buildings so nothing happened. you'll keep getting nothing until it eventually tries to spawn at the edge and will then be successful.

Not sure about that because I got precisely 3 obstacles a day when I had larger spots open. Never missed a single obstacles and I have a TH10 villages with everything built.

The programer in me thinks the way that they implemented the obstacle spawning routine is that every 8 hours the program picks a random location on the map and tries to put an obstacle there. If the area is occupied it then picks another random location and tries to put it there. It tries this 5-10 times and after that it gives up if it doesn't find an open spot. The more area then that your base occupies the less likely the algorithm will find an open space to put an obstacle.

The algorithm only tries a certain amount of times, yes. so less spaces may mean slower spawn rate
