Millions of Britons take part in the various lotteries on offer, in the hopes of winning big and bagging an early retirement. There are dozens of lottery games available in the UK, with specific rules - and in some cases, dramatically different odds of winning something.

Draws like the National Lottery and the Postcode Lottery are among the most popular, and many Britons also put money into Premium Bonds, a lottery-based savings account where people can win tax-free prizes.

But what are the chances of actually winning prizes with these draws? Read on to find out.

The National Lottery runs a number of games, with popular draws including Lotto, EuroMillions, and Set for Life.

According to , an independent website that providing results and information about various lottery games, the odds of winning the Lotto jackpot or a share of it (by matching six numbers) is around 1 in 45million.

The latest draw has an estimated jackpot of £3.8million as of Thursday afternoon (May 22). Other smaller prizes can also be won, including a £1million prize for matching five balls and the bonus ball (with odds of around one in 7.5million). The rest are much smaller, though the odds of getting something, such as a free lucky dip, are said to be 1 in 9.3.

EuroMillions tends to offer a much larger jackpot. It starts at €17 million (around £14.2million) but rolls over to reach even more staggering sums. The current jackpot is an estimated £156million.

However, the odds of winning the top prize are even more remote than Lotto. The likelihood of getting the five numbers and two stars needed bag the bumper sum is said to be around 1 in 139million.

Like Lotto, there are also lower-value prizes, including the second top prize (estimated to be £130,554.30 in April) for matching 5 balls and a lucky star, all the way down to a £2.50 prize if you get two main numbers. The chances of winning something are around 1 in 13.

In Set For Life, players have the chance to win £10k a month for three decades. To take part, players choose five numbers between 1 and 47 and a "LifeBall" between one and 10. Winners of the top prize must match all the numbers, with odds of around 1 in 15.3million according to the 's website.

Hopefuls can can play up to seven lines of numbers and buy up to 10 payslips at a time.

There is also a second prize of £10,000 every month for a year for those who match all five numbers without the life ball, with odds of around 1 in 1.7million.

Set for Life offers a descending scale of prizes with the lowest at £2.50 for two main numbers. The odds of coming away with something are 1 in 12.4, according to lottery.co.uk.

People's Postcode Lottery is a subscription lottery which launched in Britain in 2005 and raises money for charities.

According to an FAQ on the not-for-commercial-gain organisation's website, it "isn't possible to predict the likelihood of winning a prize in future draws as this depends on the number of postcodes and tickets entered into the draws," which can vary.

It adds that as a guide, "14.51% of playing postcodes won a prize from April's draws".

But unlike normal accounts, customers can put money into premium bonds and the interest paid is decided in a monthly prize draw.

Investors can win between £25 and £1million, tax-free. The product was started partly as a way to encourage Britons to save, and is said to be 100% secure.

According to NS&I, the chances of winning a £500 prize with a £50,000 holding are 1 in 53 and a £1,000 prize is 1 in 158, as of Tuesday afternoon.

The organisation said the odds of winning a higher value prize each month is lower. A person with a lower holding of £1,000 has a 1 in 23 chance of winning any prize value. A £1 Bond currently has a 1 in 22,000 chance of scooping a prize each month, it says.

Odds vary depending on the NS&I's prize fund rate which investment firm explains is the "total in prizes paid out each year as a proportion of the total held in Premium Bonds".

When the prize fund rate is higher, NS&I hands out more prizes in each draw, explains.
