The increase in the price of a ticket is the first since the National Lottery was introduced in 1994.
It will mean bigger prizes, with the average Saturday jackpot increasing by almost a million to £5m and Wednesday's rising to £2.5m.
Lottery players who get three matching numbers will get a bigger payout of £25 instead of £10 and four numbers will rise from £60 to £100.
However the amount paid out for five matching numbers has dropped from £5,000 to £1,000.
The prize for five matching numbers and the bonus ball has halved to £50,000.
Saturday's Lotto will also now feature a raffle with 50 prizes of £20,000.
Camelot is holding two £10m jackpot draws to mark the launch of their new game.
The special draws, to be held on Saturday and next Saturday, will also see 1,000 raffle ticket holders winning £20,000 on each occasion.
A National Lottery spokesperson said: "As well as giving players more ways to win more money, new Lotto will also be helping to raise more funding for National Lottery projects all over Northern Ireland.
"Each week, National Lottery players raise £35m for Good Causes in the UK."
A survey carried out by the National Lottery has found that people in the region believe the number 17 is the luckiest, despite it not being a regular feature in the main draws.
"Northern Ireland has celebrated no fewer than 20 millionaires in less than three years - maybe they have some insider knowledge in this part of the world," the spokesperson added.
"And let's not forget that the biggest ever individual Lotto winner, Iris Jeffrey, who won £20.1m in July 2004, was from Belfast."
Since the start of the weekly lotto, 67 millionaires have been created in the Northern Ireland.
