When you see the ad for Tile Match Crush, keep the google play page open, download it and if it is nsfw, play a few levels, open and close it a few times, uninstall it. Install the mod version, play a few levels, if still sfw, clear only the cache, and try to get the NSFW version. If it doesn't work, you can still get the NSFW version back because the google play page is still open. Just download it again.
