An eye-watering £77 million is on the line with tonight’s (Tuesday, October 18) Euromillions that could well change your life.

As far as National Lottery sums go, this one is indescribably huge – and just think of what you could do with that much cash. The possibilities would be endless.

If you want to play, though, you’ll have to act fast, as the draw closes soon.

So, how you can you enter the draw for the mouth-watering sum?

If you’re feeling lucky, here is everything you need to know.

How to enter tonight’s Euromillions

You can buy tickets online at the National Lottery website where you will have to create an account.

Alternatively, you can buy tickets at participating retail outlets, newsagents, and supermarkets.

Pick five numbers from one to 50 and two Lucky Stars numbers from one to 12.

You can play up to seven lines of numbers and buy up to ten play slips at a time.

A ticket costs £2.50 and includes automatic entry into the UK Millionaire Maker draw, which guarantees to create new UK millionaires every week.

If you’d like to take part in the game, remember: you’ll need to buy your ticket before 4.15pm.

How do you know if your ticket is a winner? Plus how to claim your money

If you bought your ticket online or via the National Lottery app, you’ll get an email letting you know you are a winner after the draw has taken place.

For those who bought a ticket in-store, you can scan it in using the National Lottery app.

The results of the draw will be posted on the National Lottery website after it has taken place.

If you’ve won, then you will need to call the National Lottery on 0333 234 44 33 to arrange for your claim to be processed in person, since the amount is more than £50,000.

What time is the EuroMillions draw?

The EuroMillions draw takes place at 8.45pm UK time.

You can watch it live on the National Lottery website or its YouTube channel.

All results are posted on the draw history from around 9.30pm every Tuesday and Friday.

What happens if no one wins tonight’s EuroMillions draw?

If no one wins, the prize will roll over into the next Euromillions draw.

The EuroMillions jackpot caps at €220m.

Once the cap is reached, it must be won by the fifth draw – and if no ticket matches all five main numbers and two Lucky Stars, it rolls down into the prize tier where there is at least one winner.

That could result in many new multimillionaires.

EuroMillions draws take place every Tuesday and Friday at 8.45pm.
