The headline numbers
Lotto currently includes two rounds per entry, with published odds of winning the jackpot of 1 in 22,528,738. By comparison, a single-winner online prize competition with 100 valid tickets gives one ticket a 1 in 100 chance. That is more than 225,000 times shorter. Even a draw with 1,000 valid tickets gives one ticket a chance more than 22,000 times shorter than the Lotto jackpot. A limited-ticket draw and a number-matching game use different entry pools and award rules, so the price and prize matter as much as the headline figure.

But the prizes are different
This is the important nuance. A lottery jackpot can be millions of pounds. Online competitions typically offer prizes worth anything from £50 to a few thousand pounds, including phones, laptops, cash and experiences, with houses and cars at the top end. You are not comparing like for like. A shorter chance of winning does not prove a better purchase: one £5 ticket in a 100-ticket single-winner draw has a 1% chance of winning and a 99% chance of not winning, and five tickets cost £25 for a 5% chance. What you are really comparing is the chance of winning something you want, at a cost you are comfortable with.
Expected value: what your money actually buys
Expected value is a useful way to compare. It tells you, on average, what a single ticket is worth in prizes. Lottery operators return roughly half of ticket sales as prizes, with the rest going to good causes, duty and running costs. For an online competition, the maths depends on the specific draw. A £2 ticket in a sold-out, single-winner competition with 100 tickets for a £150 prize has an expected value of £1.50. In both cases the expected value is below the ticket price, which is why entry should be treated as entertainment rather than a way to make money.
Expected value example
Competition: 100 tickets at £2 each, one winning ticket, prize worth £150. Expected value per ticket = £150 ÷ 100 = £1.50. That means for every £2 you spend, the average prize value is £1.50, a 75% return on average, while most individual entries win nothing.
A cap is not the final entry pool
The denominator is the number of valid tickets included in the draw, which can differ from a published cap if tickets remain unissued. Tickets remaining describe availability, not your final chance. Check whether paid, postal and promotional entries share the same pool. For worked examples, see competitions with the best odds.
The psychology of odds
Humans are notoriously bad at understanding very large numbers. The difference between 1 in 1,000 and 1 in 22 million does not feel as dramatic as it actually is. One way to picture it: with one Lotto entry a week, the average wait for a jackpot at 1 in 22,528,738 would be more than 430,000 years. With one ticket a week in sold-out 100-ticket draws, the average wait for a win would be about 100 weeks. These are averages, not promises: every draw is independent, and you could enter for far longer without winning.
Multiple tickets and improved odds
Both lotteries and competitions allow multiple entries. Buying 10 distinct Lotto entries improves your jackpot chance to 10 in 22,528,738, which is still vanishingly small. Holding 10 tickets in a sold-out 100-ticket single-winner draw gives you a 10% chance, at ten times the cost. Additional entries make a far more visible difference in competitions with low ticket counts, but they never remove the chance of losing.
Repeated entry does not guarantee a win
There is no deadline after which you are due a prize. In independent draws, past losses do not improve the next entry's chance. An average waiting time is not a promise or a spending strategy. Do not increase spending to recover earlier losses.
Why we show odds upfront
At Odds Up, every competition displays the total ticket count and the number remaining before you enter. If a single-winner competition sells out at 50 tickets, you know one ticket is a 1 in 50 chance. That is why we group our draws as low-odds competitions, why our guide to finding the best odds competitions walks through how to compare draws before you commit, and why we published a four-game comparison of UK lottery odds that links to the official procedures. Read the current competition details and postal instructions before you enter, or enter for free by post.
Responsible play reminder
Better odds do not guarantee a win. Prize competitions are a form of entertainment, not an investment. Only spend what you can afford, keep money for essentials separate and never chase losses.
