In Vietnam you can bet on international tennis tournaments that are widely followed locally, including the Grand Slams (Australian Open, Roland‑Garros, Wimbledon, US Open), ATP Tour events (Masters 1000, 500, 250), WTA Tour tournaments and Challenger/ITF events that feature Vietnamese players; domestic tennis activity is mostly national championships and Davis Cup/Fed Cup ties when Vietnam competes, which bookmakers list during those fixtures. DexWin - Best Odds on Your Favourite Sports

Yes — live in‑play markets are offered for international matches involving Vietnamese players and major tournaments, with dynamic markets such as next game winner, set winner and match handicaps; in Vietnam the most popular live options are game‑by‑game and total games markets and DexWin provides real‑time markets and streaming-compatible odds for fast in‑play action.

Standard industry practice applied in Vietnam markets is that bets stand if a match starts and reaches the market’s required completion threshold (for many markets this is at least one completed set or a specified number of games); if an event is postponed/abandoned before the market’s official start or the minimum play is not reached, stakes are usually voided and refunded according to the bookmaker’s rules — check specific market rules and event status on DexWin before wagering.

Vietnam’s strongest sports on the regional and continental stage are football (soccer), where the national team and youth sides perform well in AFF and SEA competitions, and individual sports like badminton, sepak takraw and weightlifting which have produced SEA Games and Asian medalists; tennis is growing with increasing grassroots and national championship activity but remains behind those traditional strengths.
