Implicating strip_mahjong, tenbou, mahjong_tile -> mahjong.
strip_mahjong -> mahjong:
Which means removing strip_mahjong from images which don't also include any mahjong tiles/tenbou. All those Evangelion CG sets/calenders don't qualify in my opinion.
tenbou -> mahjong:
Only if there isn't another game which uses these sticks.
mahjong_tile -> mahjong:
Needs restriction, like "Use if there is only a single mahjong tile in the image" or for people holding tiles, but not playing mahjong. Same with chess_piece by the way.
edit: changed tenbo to tenbou after glasnost's post.
Also
tenbo -alias or edit-> tenbou
pointless wiki tenbo
