I got the NSFW version this time.
Watching YouTube. Got an ad for Tile Match Crush. You must follow this procedure because all the other times I downloaded from youtube, it did not work because the current version was sfw which was already loaded into the data area.
Please note. Today I opted to be a Beta tester at Google Play. This may be crucial to always get nsfw versions?
From youtube ad, direct to Google Play. Keep it open. Current tile match crush, Delete the data and cache. Uninstall it. Download tile match crush. Open it, do not touch anything. Close it. Delete cache only. Open tile match crush and play 2 levels. On the 2nd level you will already notice a difference; it is nsfw. Finish the levels for Seraphine. Keep the Google page and youtube open. Uninstall tile crush match. Install the mod version of Tile Crush Match. If it is sfw, close it, delete only the cache. Play a few levels. If all else fails, you still have the Google play page to get the nsfw version.
