UK Lotto Rules & Odds

Six numbers are drawn from a set of individually numbered balls with numbers in the range 1–49, as well as a further bonus ball. Balls, once drawn, are not returned to the draw machine, therefore each ball (including the bonus ball) can only be drawn once per Lotto draw. Players choose six different numbers by a method of their own choosing at the time they purchase a ticket. Ticket issuing machines can generate a random set of play numbers as a so–called Lucky Dip. Prizes are awarded to players who match at least three of the six drawn numbers with increasing prize value for matching more of the drawn numbers. In addition to the six drawn numbers, an additional number is drawn as the Bonus Ball. The bonus ball is only relevant to those players who match five of the six drawn numbers, whereby those players matching exactly five of the drawn numbers who also match the bonus ball receive a larger prize than those matching just 5 of the drawn numbers. Anyone matching all six drawn numbers wins a share of the jackpot; the chance of doing so is 1 in 13,983,816. For players matching at least four of the drawn balls the prize value is dependent on the total number of players also matching the same number of balls in that the prize fund is divided equally between all players matching that number of drawn numbers. In the event that no player matches all six of the drawn numbers the jackpot is accumulated into the next Lotto draw, a so–called Rollover. This accumulation is limited to three consecutive draws. Rollover is a common occurrence, happening once every few draws, though a three week roll-over is a rather less common occurrence having happened only twice to date.

The entry fee to the Lotto draw is £1 per board

The draw is conducted on Wednesdays and Saturdays. Saturday draws started on November 19, 1994, under the name 'National Lottery'. The first Wednesday draw was on February 5, 1997. All draws are shown live on BBC One in the UK, with the Saturday draw shown as a segment in a range of different Lottery branded gameshows throughout the year.

The game was rebranded 'Lotto' in 2002.

The Lotto prize fund is 45 percent of draw sales. Camelot state that the 3 ball prize winners are calculated first, these receive £10 each; the remaining prize fund is then divided as shown in the table below and split equally with the number of winners for each selection:

Match	Prize	Approximate odds
3 numbers	£10	56:1 (i.e. 1 in 57)
4 numbers	22% of remaining fund	1,031:1
5 numbers	10% of remaining fund	55,490:1
5 numbers and bonus ball	16% of remaining fund	2,330,635:1
6 numbers	52% of remaining fund	13,983,815:1 (i.e. 1 in 13,983,816)

The 6/49 mentioned above also had an optional add-on game known as Extra which could be played for an additional £1. However, its only prize was for matching all six regular numbers drawn for the 6/49 jackpot (there were no lower-tier prizes; you lost even if you matched five). It was discontinued in 2006.

You can improve the above odds dramatically by playing in a syndicate.
