I noticed that the site became pretty slow since mellowads are start appear.Site is load slow and I see it is waiting for mellowads to load,but I notice that also on FaucetHub today.Maybe there is some problem with mellowads or there is problem with server/hosting.I hope to see site is working fast as before

simply log off from gmail from the browser where you using virtualpub

So I'll throw a quick newbie thing together here.

The whole key to this game is to keep your bartender working (not sleeping) and to keep your bar stocked.
It's a slow grind to get your bar to level 2, but you need to buy access to wine and whisky as soon as you can to help speed things up.
Once your bar is lvl2, you need to figure out a buy order for your bartender/seats/storage.
Each one has it's obvious gain and you need to figure out your play style.
Bartender extends time between needing to pay your bartender.
More seats will make you sell drinks faster.
More storage will help you hold more (duh).
If you only check in once and a while, you'll probably want bartender, storage, then more seats.
If you are on all the time, you want more seats first and the other two in either order.

Next big thing is to keep doing your "Task Reward", you can get this a couple times a day if you are really active and it helps a lot, especially when it gives lucky coins.  Remembering to keep on top of your task reward will remind you to keep doing your events, bonuses and shorteners (when needed)

When you get your inventor and scientist, you will likely be able to keep your inventor working and buy upgrades at the same time as your science points build.  But keep that inventor working is a priority.  Here is a list of inventions posted by another user:

And lastly, the Lottery.  
The lottery goes off whenever it reaches 5000 tickets and usually goes off multiple times a day.
You can get upto 200 free tickets for each round by going through an advertisement for each one.
You CAN win more than 1 of the top ten prizes in any single lottery.

Some last side notes:
1. The "Big Event" isn't anything special, it's like a poor mans task reward.
2. To prevent having to solve shorteners twice, wait for them to load fully and then click somewhere on the screen.  If it is going to pop another one up, it will do it then.
3. The lottery can really boost you along if you can get lucky enough to win early. Getting 200 (max) tickets out of 5000 will give you a 4% chance to win each prize during that lottery (my luck has been brutal, but I'm sure their are lots out there praising the lottery).  It's free tickets, it just takes a lot of clicking.
4. As with pretty much any Satoshi game out there, it's pretty slow at the beginning, but if you can get it going it's a decent earner.

I hope this helps you or any other newer player(s) out there get a better idea of how to progress in this game.
Have fun everyone!!

you will need 200 science points every 24 hours to discover inventions . After you discover all the inventions you don't need science points anymore and you can convert them all to credits .

It is his satoshis or credits but not the referrals earnings.
You get the referral earning directly to your faucethub account when he withdraw, you will see on your faucethub account an entry with ultramarine background "REFERRAL" instead of green "NORMAL" entry type.

It depend on where you are in the game. Work on these ratios and fine-tune from there.

Beer: one sold every minute for every five seats
Wine: one sold every 6 minutes for every five seat
Whiskey: one sold every 10 minutes for every five seats
Cigars: something like 50% chance of selling a cigar for every whiskey sold

Note that there are conditions on these but I can't remember exactly what it was since the ratios were removed from the help file when the site was upgraded many months ago. You have something like a 2 in 5 chance of selling a whiskey every time a beer is sold. so you won't always sell whiskey or wine to these proportions but you will never sell more than these.
