9 out of 10 comments are currently about how someone can't find the episodes, drowning out the few comments about the series itself -- so once and for all:

"Dating Game" has no international release. It is streaming on two on-demand platforms, both paid: 

• Lemino (Japanese subtitles) 
• TrueVisions NOW (English subtitles).

According to @excobs and @Smart Mouse, to watch it on TrueVisions NOW you'll need:

• a paid account (119 Baht per month, not all credit cards work)
• a vpn set to Thailand

[see this thread in the comment section from this comment https://kisskh.at/786270-dating-game#comment-22885662 onwards]

One option to watch it free is linear TV, Workpoint 23 has the live stream on their website. Mondays on 21:30 Thai time, TV cut version only, no subtitles.
