The National Lottery in Ireland is reducing its Lotto ball pool and adding a third weekly draw to improve player odds [1, 2].
These changes represent a strategic shift to make the jackpot more attainable for participants. By altering the mathematical probability of a win, the lottery aims to increase the frequency of high-value payouts across the country [2, 3].
Under the new rules, the lottery will drop two numbers from the game [1]. This reduces the total ball pool from 47 to 45 [1]. The National Lottery said the move is designed to improve the odds for players, and create more millionaires [2, 3].
In addition to the pool reduction, the lottery is expanding its schedule. A third weekly draw will be introduced on Mondays starting this autumn [3].
A National Lottery spokesperson said the changes will improve players' odds, create more millionaires, and introduce a third weekly draw from this autumn [3]. The spokesperson said the update comes "with one clear ambition: to create more millionaires across the country" [2].
The reduction of the ball pool directly affects the probability of matching all numbers. With two fewer balls in play, the total number of possible combinations decreases, which mathematically increases the chance of any single ticket winning the top prize [1, 3].
“The changes will improve players' odds, create more millionaires, and introduce a third weekly draw from this autumn.”
By reducing the number of balls from 47 to 45, the National Lottery is lowering the statistical barrier to winning the jackpot. The addition of a Monday draw further increases the opportunities for players to win, suggesting a strategy to maintain player engagement and increase ticket sales through a higher perceived and actual probability of success.
