Several Irish people could become millionaires later tonight.
The EuroMillions jackpot of €230m is the largest amount ever seen in a European lottery.
The jackpot will be capped for up to a further four draws - with the additional funds that would have gone to the jackpot now flowing down to the next prize tier with a winner.
If the jackpot is still not won after the fifth draw at the cap, the full value of the jackpot will flow down to the next tier.
The National Lottery is predicting that some €21m will flow down to the next tier for Tuesday night's draw.
It is urging players to get their tickets early, which can be purchased ahead of the 7.30pm cut-off time.
A National Lottery spokesperson said: "The EuroMillions jackpot has now officially hit record-breaking levels after reaching the highest amount ever seen in the game last Friday.
"While Tuesday’s jackpot is guaranteed to be capped at the hugely life-altering amount of €230m, players will also have the chance to win even bigger than usual at a lower prize tier.
"If a player in Ireland were to win the massive jackpot amount... they would take the title of 18th EuroMillions jackpot winner ever seen in Ireland."
