Hey, dudes, I've gotten help from this subreddit many times, so I figured it was time to pay back some of that good will. I just completed the Billionaire Casino to Level 160 offer in about 8 days with no purchase, and I bet most of y'all are like me, in that:
- You want to get this done as fast as possible.
- You are mystified by the janky systems of Billionaire Casino.
First off, it's about knowing which slots pay better than others, and how much time it'll take for each to become profitable. That said, here's what I did, with some notes to help.
1) When you're starting out, bet no more than 5% of your chips on a single pull. 75% of getting "good" at BC is overcoming the gambler's fallacy: you might think you can predict the slots, but you are dead wrong, and you will end up a virtual penniless pauper.
2) If you get above 1,000,000 chips, only bet 1% at most. The only times to go back to 5% are if you're either below 1 million again, or if you have a 2X experience boost, which is fairly invaluable.
3) Join a league as fast as possible, and have absolutely no loyalty. You are Benedict Arnold to the nth power. As soon as you see a better league, jump on it. Overnight, you should get a ridiculous amount of chips from shared jackpot and challenge prizes.
4) Recognize that most of the slots will drain you dry without giving much in return. From what I've seen, here are the ones worth playing:

• Blaster Cats vs. Aliens - pays out pretty well, so I played this one almost exclusively until hitting level 90 or so.
• Sky God - less reliable than BCvA, but when it pays out, it pays the hell out. If you've got a sudden influx of chips, try this for a bit. If you start losing, retreat to the safe harbor of BCvA.
• Camelot Cash - even less reliable than Sky God, but pays out ridiculous dividends. On a bet of 10 million, I walked away with 8 billion. Make sure you have enough to wait this one out, because endurance will be key to reaching a really big win.
• Any Huge Link game - these are risky, because they're probably the least reliable out of any of these, but, as you've probably guessed, they pay out a ton. The trick with these, and any, is not to be "lucky," but to be smart with your betting and only go in when you can afford to lose a lot while you wait for the ginormous payout.
• Buffalo Rush - the best one, hands down. If you get a lot of chips (think at least a million) head straight here. The payouts are high, frequent, and on a ridiculous 1024 paylines.
• Huuuge Bucks - another ridiculous payout with low reliability, though the kicker is you need to be a high level to play this one. I played while it was free for some kind of event. Locked slots go through that every so often.

5) Set Autoplay to run with the minimum bet on Buffalo Rush overnight. You might end up bankrupt, you might get a ton, or, most likely, you'll wake up around where you started but with significantly more XP.
6) Don't be afraid to lose it all. We're conditioned to hate losing, obviously, but, surprisingly, the game gives you a lot of chips a lot of the time. Every 15 minutes, you'll get a respectable sum, actually. Make sure to check the Billy Bonus (every 15 minutes), the shop bonus (every 8 hours or so), the lottery free tickets (also 8 hours, I think), and your Billionaire League bonuses.
7) Make friends, not because it's good for the soul or anything, but because the more friends you have, the bigger a bonus you get at the start of every day.
8) Meditate in order to calm the murderous rage you'll feel when you see Billy, the app's mascot.
Good luck, my dudes. I'll try to answer any questions y'all might have, so feel free to ask here or PM me if you're shy.

Overview

Edit: Just to make things clear: There's an offer on AdGate to reach a certain level in this game. Your earnings aren't determined by your luck with gambling.
 
As the name implies, this is a slots game. That means it is entirely luck based, and every user is going to have a different experience with it. I ran out of chips at level 53, the next day I struggled to gain chips, and the following day I woke up to 450m chips which I then quickly tripped that to 1.2B chips. This barely got me to level 100 before suddenly winning another 3B chips on my last auto-spin.
This game frequently gives out chips, and there isn't a specified deadline. Considering this game practically plays itself, it's definitely worth doing.
Edit 2: I took a look at Huuuge Casino Slots as mentioned by u/jraspberry and it seems to be almost exactly the same. There are just a couple differences with names. This offer is $17.66 with 2x Adgate on Swagbucks.
 
^{Just in case someone doesn't know the common conversions - K stands for thousand. M stands for million. B stands for billion. So, 500m would be 500 million or 500,000,000.}
 

Offer Name	Billionaire Casino™ Free Slots 777 & Slot Machines
Offer Wall	AdGate Media
Device Used	I use Android. I do not know if it works on iPhones.
Amount	I got $18.40 from Swagbucks on their 2x SB day. Today 2/7/20 is a 2x AdGate day.
Time Limit	None mentioned.
Time Spent	I got to level 53 the first day before running out of chips. I completed the game in under 3 days. Total hands on time was maybe an hour tops. It mostly plays itself.

 

How to play & Tips

As the name implies, this game is about slots. (Note: They do have other games, but I didn't touch those.) Thankfully, they also include an auto spin feature, so you don't have to give it much attention. Just long hold the spin button until it starts auto spinning, and away you go. You may need to play the first game a couple times before this unlocks.
The goal of the game is to get to level 100. You gain XP simply by playing the game and spending chips. Spending more chips will give you more exp, and it seems to go up at a linear rate. I chose to bet 1% or less of my balance to prevent any heavy losses because my luck generally sucks. While it does feel slower, the game is playing itself, and I wasn't in a rush.
As you level up, you will gain access to more boards. If you are having a bad streak with one game, you can just swap to a different one. Make sure to use up any free spins before swapping games though, as they are forfeited when you leave. There is also a "Basic Pass" event you can do and you'll get a good amount of chips for hitting the goals for certain games. You can find this on the home page or in the individual games. If you're going to play a game anyways, might as well get the bonus. (Note: I played for less than 3 days, so this event might change).
At certain levels, you will get a 2x XP bonus for 5 minutes after hitting that level. These are often in the reward box every 5-10 levels. However, it also seems to happen with every level up starting around level 80-85. Since it's timed, it may be worth upping your bet during this time period.
Every so often you'll get a mini game that pops up. Some will autocomplete, others give a higher bonus for doing yourself, and some just disappear. If you notice it, it might be worth doing manually.
You will definitely want to join a club. It gives you 1M chips just for joining, and you'll get all sorts of bonuses. You can do this by tapping the Billionaire League button on the bottom bar of the home page. There didn't seem to be any individual participation bonus for participating in the club events, so you can chose whether or not to do them.
 

Getting More Chips

There are a number of ways to get free chips in this game.

• You can get the Billy Bonus every 15 minutes. It is located on the bottom left hand corner of the home page. It doesn't give a lot, but it helps with the daily quest.
  
• You get one free spin of the lottery every 6 hours. You will also get tickets as you play, usually from leveling up. This is located on the bottom bar on the home page.
  
• You get a free Shop bonus every 8 hours. This is located on the bottom right of the shop page.
  
• You get a bonus for completing daily missions. You get 100k for each of the following: Spin 250 times. Hit a big win 3 times. Hit a free spins 3 times. Collect 3 Billy bonus. You also get an additional 500k for completing all of those.
  
• You can get club bonuses. After joining a club, click on the "Billionaire League" button located on the bottom bar of the home page. This will take you to your club page. From here, you want to click on the "Club Wall" Tab. You then need to tap each one of the green buttons showing you a chip amount. Make sure to check on this every 12 hours or less, as some of these will expire in 12 or 24 hours.
  
• At the start of each day, you will be given some chips. You get 1k chips per friend added (up to 25 friends). You will get 100 chips for every like you get (up to 100). You will get 1k chips per day streak. For example, on day 3 you will get 3k chips. You also get a spin of the roulette that will award up to 1.5M chips.
  
• You can get 500k chips for connecting to your Facebook account. This seemed like a lot at first since you only start off with 5M chips, but in the long run it didn't feel too necessary.
  

 

Should you spend real money?

Spending money would definitely speed up your completion time. It's by no means necessary, but even spending $1 or $2 would let you finish the game quickly. Just look for the popups where you earn 300-350% more. I frequently saw a $1 offer for 70M chips, and a $2 offer for 168M chips. You can pull these offers up by hitting the "News" button on the bottom bar of the home page.
That being said, considering the game practically plays itself and there's no time limit, I didn't feel a need to spend anything.
 

Other Features

This game has a number of additional features, which you don't necessarily need to participate in as they don't benefit you. I'm putting them here for completeness, but you can just skip over this section if you aren't interested.

• You can give drinks to users. I'm not entirely sure what this does, but I think it might send chips to others. You can buy the drinks for points. You can also give a free drink when a certain condition is met (it never stays up long enough for me to read it). When winning a jackpot, sometimes it'll let you send out a round of drinks to the other players. You only get 3 seconds to do this, so accept it quickly.
  
• You can like users every 60 minutes. This will help with their daily goal.
  
• You will get some diamonds. They seem to only be good for unlocking boards before getting to the required level and for giving out "drinks" to users.
  

 

General Tip:

When you click the offer on the offer wall, download the app right away. As soon as it's done downloading, open the app right away and let it run for a while (play the game, make an account, let it sit, whatever). Do not navigate away at any point during the process. Taking too long or messing around while the game is downloading/installing may cause problems with it crediting later.
 
 

Common Questions

Can I do this if I already completed it on another offer wall or played the game before on my own?

Generally, no. Almost all of these games state that it's for new users only.

What if I do it on another site?

No.

I don't see the offer! What do I do?

It's possible it simply isn't available for you. I'm from the USA, and many offers are not available outside the USA. If you are from the USA, try checking on the site I did the offer on or on a different site. Sometimes they're only on certain sites. It's also possible that the offer is no longer available.

I completed the task but I didn't get credit for it! What do I do?

First, wait 24 hours. Most of these games credit within a few minutes, but they may take up to a day sometimes.
Next, check to see if the offer has been completed through the offer wall. If it has not, you must contact the specific offerwall that you completed the task on. For example, if you do this task on Site-xyz through AdGate you have to contact AdGate. If the offer shows as completed but you did not get your points, then the points may have been held and you will need to contact the specific site.

This takes so long! Why would you waste your time for a couple bucks?!

I play these games in between other work or on the weekends. I don't do them instead of better paying work, but rather along side it in my down time or while I'm watching TV. Most of it is just waiting around for it to do its thing. I'm also a gamer, so I enjoy playing games.
