Same court, same faces, and yet the air changes completely depending on whether the game counts for DUPR. I regularly get invited into Vietnamese-majority socials in Ho Chi Minh City, and this gap is the part I find most interesting. What follows is only what one player, neither a pro nor a coach, has felt within the range of people he has played. Please read it as a personal view.<\/p>\n
In the socials I join, games submitted to DUPR and games that are not are clearly separated.Games that do not count for DUPR are startlingly relaxed<\/strong>. They laugh along when I make a silly mistake, and even a first-timer gets folded in naturally.<\/p>\n The moment a score is at stake, though, the same person's expression changes. I hear of players getting frustrated with themselves over a single error, and the amount of talk and the density of concentration during a game are plainly different. Not in a bad way, they simply take competition seriously.<\/p>\n Knowing the background makes part of it click. According to DUPR, Vietnam is among the world's top five countries by registered users, with the highest month-over-month growth rate on the platform. DUPR opened its first regional base in Asia in Ho Chi Minh City in April 2026. Facolos Champion 2025, held in January 2025, was the country's first large tournament with more than 300 entrants that sent every result to DUPR.Here a DUPR number connects directly to which sessions you can join and to proof of your level<\/strong>. The number carries weight, so of course they get serious.<\/p>\n Once I understood the gap, I changed how I pick sessions. On days I only want to move my body, or days I want to get to know faces at a court I am visiting for the first time, I join a session without DUPR. On days I want to measure where I stand, I deliberately sign up for a scored one. The word social covers two different things, so checking on the sign-up page whether results go to DUPR keeps your expectations for the day in line.<\/p>\n This needed getting used to before anything about play itself. Within the range I have faced, calls can be fairly loose.<\/p>\n The call on a ball landing on your side belongs to that side's pair. So even if I think it was in, if the other side says out, out is how play proceeds. There is no referee.When you do not accept it, the only option is to say so clearly on the spot<\/strong>. Let it pass in silence and the same call repeats within the same match.<\/p>\n The reverse happens too. A ball was clearly out so I called it on myself, and the opponent would not budge, insisting it was in. The instinct is to defer and back down, but standing firm here makes the rest of the session go better.<\/p>\nThe number carries weight, so they get serious<\/h3>\n
Line calls do not go your way unless you speak up<\/h2>\n
A ball that looked in gets called out<\/h3>\n
Your own call against yourself can get pushed back<\/h3>\n
