Dueling Network is an online simulator for the ever-popular children's card game Yu-Gi-Oh!. It's home to one of the biggest communities in Yu-Gi-Oh! fandom (Dueling Network even has its own forum!) and is home to a lot of things (e.g., trolls, spammers in public chat, lots of admins, derpy players) which make it big and bad. Despite this, the site is very popular and many people have joined. Most notable is that unlike other Yu-Gi-Oh! simulators (YGOPRO, for example), Dueling Network is not automatic, so ruling mistakes and inconveniences happen often.
The network was created by BLS, and is maintained by a variety of good-natured admins and moderators. So it isn't often that the various trolling attempts go on for long.
On 5th July 2016, the site was rendered offline 'until further notice' following a copyright battle with a third party company.
- Atomic F-Bomb: A lot of trolls and rage quitters will drop this.
- Executive Meddling: A copyright order from a third party of Konami (NAS) ordered that all images on the site be removed. This left the site with a barren simulator and had its userbase slashed by up to 80%. Despite numerous workarounds, the site was eventually disabled altogether; with other simulators like DevPro taken down soon after.
- Game-Breaker: In a literal sense, the card 'Convulsion of Nature' makes the game virtually unplayable, since there is no way to flip your deck upside down without moving all cards to the graveyard or banished zones, and makes it even worse if you need to shuffle your deck. For this reason, many of the mods banned it from ranked matches.
- Graceful Loser: A losing duelist may admit defeat and tell someone good game before leaving.
- Luck-Based Mission: By definition of the game, though it can be alleviated by lowering the total card count of your deck and adding more of certain cards.
- Rage Quit: As much of a staple as the real game.
- Random Number God: Also known as DN's Shuffler.
- Serious Business: Just read that page's quote.
- Sore Loser: A losing duelist may just quit out, but at the cost of rating in a rated game. A really bad duelist will, say, jack up their life points or play monsters when you're not looking.
- Stop Having Fun, Guys: Children's card games are Serious Business.
- Timed Mission: Decking out is a common way to lose for some decks. Playing against Mill decks count especially.
- We Win Because You Did Not: Self Destruction Button decks work off of this philosophy.
