Wild Card: Side Bets

 is a quest in Fallout: New Vegas, given by Yes Man.

Quick walkthrough
Just follow the quest markers and make communication with each faction, then you can go back and talk to Yes Man and tell him to ignore that faction and continue on with the chain. You may get the faction to like you, you then can tell Yes Man that they are on your side.

Detailed walkthrough
The factions you need to talk to are:


 * The Boomers at Nellis Air Force Base
 * The Brotherhood of Steel at Hidden Valley
 * The Great Khans at Red Rock Canyon
 * The Omertas at Gomorrah Casino
 * The White Glove Society at The Ultra-Luxe Casino

Each of these factions can be met in any order, and all have a quest associated with them. If you tell the Yes Man to ignore the faction you do not have to complete their quest to finish Side Bets, but many of the factions will aid you in the battle for Hoover Dam if you choose to complete their side-quest chain. Even if you've told Yes Man to ignore a faction you can go back once you've earned their assistance and change your opinion of them through dialogue.

Essentially this quest is just a guidepost quest that points you to the other factions, actually earning their aid or solving their problems requires you to complete a side-quest that usually gives you reputation (reputation with The Strip for the casinos, or with the Boomers, BoS or Khans respectively) and sometimes special benefits.

For the Brotherhood of Steel problems, you have two solutions.
 * Destroy Hidden Valley. Hack the self-destruction terminal on second floor (Very hard), or pickpocket 3 keycards (from Elder McNamara, Head Paladin Hardin and Head Scribe Taggat) so you can generate password for self-destruction. When you activate the self-destruction protocol, the whole base will go hostile. Hacking the turret control console in Paladin Ramos' room, and set the turrets attack Brotherhood of Steel members might be helpful.
 * Make Brotherhood of Steel to support NCR. Proceed NCR quest line till reach For the Republic, Part 2. Colonel Moore wants to eradicate Brotherhood of Steel, and you can negotitate with Elder. (McNarama confirmed) Elder decides to support NCR to avoid conflict with them. You can report to Yes Man instead of Colonel Moore.

To solve the Boomers' problems you must complete the quest Volare!, this gives you their assistance in the Battle of Hoover Dam (by way of a pre-war heavy bomber) and the ability to come and go freely from Nellis

The Great Khans can either be convinced to help you by completing the quest Oh my Papa or they can be convinced to leave the Mojave for more fruitful areas.

By dealing with the White Glove Society's problems with cannibalism during the quest Beyond the Beef you can tell Yes Man that you fixed their problem, solving their portion of the quest.

At the Gomorrah you can pick up the quest How Little We Know. If you choose to aid Cachino in breaking up what the bosses have planned then you can inform Yes Man of this fact.

Once all the factions have either been ignored or their side-quests done, you simply have to talk to Yes Man again to complete the quest.

This quest is probably the longest in the game, simply for the fact it has five components and each of those is a quest chain with between 2 and 7 parts.
