Lotto HotPicks is a popular spin-off game that utilises the main numbers from the flagship UK Lotto draw. Players choose their own level of risk and reward by matching anywhere from one to five numbers for fixed cash payouts, with every line getting two chances to win across Lotto’s Round 1 and Round 2.
People's Postcode Lottery
The People's Postcode Lottery is a subscription-based game where winners are determined by selecting postcodes across Great Britain at random. When a postcode is chosen as a winner, all players residing in that postcode are eligible for a prize! This game raises substantial funds for charities nationwide.

Players pick five main numbers from 1 to 69 plus one Powerball from 1 to 26 for £4 per line, with draws held in Florida in the early hours of every Tuesday, Thursday and Sunday UK time, and the jackpot paid as an annuity over 30 years.
Set For Life
Set For Life is an annuity-style draw game that delivers ongoing financial security rather than a single lump sum. Winning the top tier awards fortunate players a steady stream of £10,000 every single month for 30 years.

Draw Mechanics & Specific Terms

Advance Play
Advance Play is a convenient feature that allows players to enter their chosen numbers into multiple consecutive draws ahead of time. It ensures you never miss a draw during busy schedules or while away on holiday.
All-or-Nothing
An All-or-Nothing draw is a lottery format where players can win the top prize by either matching every drawn number or missing every single one. By rewarding total precision as well as total absence, it offers two distinct paths to the main prize tier.
Ball Machine
A Ball Machine is the specialised, mechanical device used during draws to select winning lottery numbers at random. Numbered balls are thoroughly mixed inside the machine before being released one at a time, with every draw independently verified to ensure transparent, trustworthy results.
Bonus Ball
A Bonus Ball is an additional number drawn from the remaining pool during main lottery draws like the UK Lotto. It acts as a secondary match option, elevating Match 5 winners into a significantly higher prize tier.
Double Draw / Round 1 & Round 2
A Double Draw is an event structure where a single entry gives players two distinct chances to win across consecutive draw phases. Every Lotto and Lotto HotPicks ticket is now entered into both Round 1 and Round 2 on each draw night, with each round using separate winning numbers for no extra cost.
Game Procedures / Game Rules
Game Rules are the official regulatory documents governing player eligibility, ticket validity, and prize payouts for each draw. They ensure absolute fairness, transparency, and consumer protection across all lottery operations.
Life Ball
The Life Ball is the critical extra ball drawn in Set For Life. Matching this key ball alongside the main numbers unlocks the top tier's long-term monthly payouts.
Lucky Stars
Lucky Stars are the two supplementary numbers drawn from a dedicated secondary drum in the EuroMillions game. Hitting both alongside the five main numbers is required to unlock the top jackpot.
Match Tiers / Prize Tiers
Prize Tiers are the structured levels of payout awarded based on how many winning numbers a player's ticket matches. They ensure that lower partial matches still deliver proportional cash rewards or free plays.
Must Be Won
A Must Be Won draw is a special condition that guarantees the jackpot is paid out. In UK Lotto, it is triggered once the jackpot has gone unwon for five consecutive draw nights; if no entry matches all six main numbers in either round of the sixth draw night, the jackpot rolls down, awarding £5 to every Match 2 winner and sharing the remainder among Match 3 winners. EuroMillions uses a similar mechanism once its jackpot has reached its capped limit and stayed unwon for a set number of draws.
Pari-Mutuel
A Pari-Mutuel payout is a prize calculation system where the total prize pool for a tier is divided equally among all winning tickets in that tier. This dynamic structure means individual payouts fluctuate based on total ticket sales and the total number of winners. In UK Lotto, only the jackpot works this way, as every lower prize tier pays a fixed amount.
Random Number Generator (RNG)
A Random Number Generator (RNG) is a certified computer system that selects winning numbers purely through complex mathematical algorithms. It provides a secure, digital alternative to mechanical ball machines for instant wins and select draw games.
Rolldown
A Rolldown is a jackpot mechanism where unwon top-tier funds are redistributed to enhance lower prize levels. It transforms standard lower-tier matches into significantly higher cash payouts.
Rollover
A Rollover occurs when nobody matches the numbers needed to win the top prize, so the jackpot carries forward to boost the very next draw. This compounding effect builds momentum as prize pools increase in value.
Superdraw / Event Draw
A Superdraw is a special EuroMillions event where the jackpot is boosted to a guaranteed multi-million-pound amount. It offers elevated prize pools regardless of whether the jackpot was won in the preceding draw.
Thunderball (Ball)
The Thunderball is the distinct ball drawn from a separate pool of 1 to 14 in the Thunderball game. Matching it alongside the five main balls is essential to securing the top £500,000 cash prize.
UK Millionaire Maker
The UK Millionaire Maker is a raffle included automatically with every UK EuroMillions ticket sold. A unique code on each slip guarantees at least one player in the UK wins £1,000,000 in every single draw.

Scratchcard
Scratchcards are physical cards featuring a concealed play area revealed by removing a thin latex coating. They deliver immediate results and cash prizes without waiting for a scheduled draw.
Syndicate
A Syndicate is a group of players who pool their money to purchase multiple lottery entries together. By buying more tickets as a team, members increase their collective chances of securing a winning match.
Syndicate Agreement
A Syndicate Agreement is a written document outlining how group funds are managed, who is playing, and how winnings are divided. It ensures clear rules, transparency, and agreement among all members when a win occurs.
