Packed pubs where you have to jostle for a view of the TV are normally part of the joy of watching football tournaments.
But the government's decision to delay lifting restrictions in England means this year's tournament will be different.
Can I watch at the pub?
Pubs have been told to risk assess where TV screens are - and the volume - when making venues Covid-secure.
You can watch football inside pubs across the UK, but how many people you can sit with varies.
In England, up to six people from six households (or two households of any size) can meet.
In Wales, up to six people from six households can meet.
- Level two - six people from three households
- Level one - eight people from three households
- Level zero - 10 people from four households
In areas of Scotland at alert level two, including Euro 2020 host city Glasgow, pubs must operate two-hour pre-booked slots and close indoors at 22:30 BST.
In Northern Ireland, up to six people from two households (or any number from one household) can sit together.
In England and Wales up to 30 people can meet in a pub garden.
- Level two - eight people from eight households
- Level one - 12 people from 12 households
- Level zero - 15 people from 15 households
In Northern Ireland, up to six people from two households (or any number from one household) can sit together in a pub garden.
Can I invite friends to my place?
Each nation has different rules.
If you are inside, you should keep rooms well-ventilated, maintain social distancing and wash your hands regularly.
- In England, up to six people from multiple houses (or two households of any size) can gather inside - up to 30 outdoors
- In Wales, an exclusive extended household of up to three households can mix in private homes - up to 30 people outdoors
- In Scotland, domestic indoor and outdoor rules depend on which Covid alert level your area is in
- In Northern Ireland, up to six people from two households can meet in a private home - up to 15 people from three households can meet in private gardens
Can I hug my mates when there's a goal?
In all nations, social distancing guidelines should be followed and face coverings worn in pubs when not sitting down.
- In England, people can use "personal judgement" when hugging close friends
- In Scotland, you should maintain social distancing in public places, but you do not need to physically distance from friends in private homes
- In Wales, the government is not recommending you hug people you don't live with, unless you are in an extended household
- The Northern Ireland Executive says people should be "cautious and careful" about hugs and think about "individual circumstances"
Are there fan zones?
The official Uefa fan zone in England is at Trafalgar Square in London. Entry is free, with tickets allocated via ballot. It will screen all England games plus the semis and final.
Scotland's fan zone is at Glasgow Green. Manchester, Birmingham and other cities also have special areas.
Social-distancing and other guidelines will be in place. Fans should use the NHS Test and Trace app to check-in.
How may fans be at the games?
Fans will be at each game in 11 host cities across Europe, including Wembley Stadium in London and Glasgow's Hampden Park, but Covid rules limit capacity.
Those not fully vaccinated must show proof of a negative lateral flow test from the previous 48 hours.
Ticket holders for matches at Hampden Park will not be required to show proof of vaccination, or a negative Covid-19 test.
Will Covid rules change during the tournament?
The Euro 2020 final will take place on 11 July.
In England, lifting of current restrictions won't happen until after the trophy is lifted.
Scotland is hoping to move all areas to level zero, the lowest level of restrictions, on 28 June.
Wales and Northern Ireland are easing restrictions more slowly.
How can I follow the action?
The BBC and ITV are broadcasting the matches.
England, Scotland and Wales' opening games are on the BBC.
