There's a long day and night ahead of us, but here's what to look out for...
If a party wins in 326 constituencies - that's just over half the number of seats in the House of Commons - it will have gained a majority.
In practice, slightly fewer seats are needed. That's because the Speaker of the House (currently Labour's Sir Lindsay Hoyle) remains neutral, and Sinn Fein MPs have a long-standing tradition of not taking their seats.
If a party has a majority, its leader will head to Buckingham Palace to ask the Queen's permission to form a new government on Friday.

We'll bring you more photos when we get them.

The first results usually come in about an hour after the close of the polls.
The rest of the results - and there are 650 constituencies in the UK - are declared throughout the night and into the next day. Most counts will be completed by 06:00 GMT.

Each of the UK's polling stations has been carefully selected according to a strict set of rules, external.
So where can polling stations be located? And where are some of the most unusual ones?
Pubs, sports stadiums, religious buildings, museums, laundrettes and hair salons all feature.
Here are some of England's most unusual polling locations from the 2015 general election.
A controlled explosion has been carried out near a polling station in North Lanarkshire after a suspicious device was found.
Police said the device was found on the ground floor of Glen Tower flats in Motherwell at about 01:00 on Thursday.
A community room in the building was due to be used as a polling station for voters in the area.
The council said all those registered to vote in the tower had been asked to go to Knowetop Primary School instead.
Don't panic. Those who applied for a postal vote but have yet to return it to their Electoral Office must do so by 22:00 - but voters can also hand it into their local polling station by the close of polls.
More than seven million people put a cross next to the name of their favoured candidate via a postal vote in the 2017 general election.
It has begun.
The hashtag #dogsatpollingstations is already trending on Twitter, after polling stations opened at 07:00 GMT.
But what we are *really* loving is photos of dogs in their best Christmas garb.
The early bird voters have been posting pictures of their festive pooches outside polling stations - and they are as paw-some as we'd hoped.
We'll bring you more photos as we get them.
