A play is a 7-digit number from 0,000,000 to 9,999,999. It wins the tier of its longest run of digits matching the drawn number from the start or from the end. The 7-digit prize is a share of a fund and rolls over when nobody wins it; every other prize is fixed.
What a play pays back
A play pays back its price on average only once the 7-digit fund reaches about €2.84 million, before sharing with other winners and before tax.

How the odds are worked out
Each digit is drawn on its own from 0 to 9, so there are 10 million possible numbers, all equally likely. For each one, the run of matching digits from the start and the run from the end are counted, and the longer of the two decides the prize.
Checked against the official figures
Allwyn, which runs ΠΡΟΤΟ for OPAP S.A., publishes the rules and the prize table, but not the odds of each prize. Its table says "last 6 digits the same as the last 3" for the 3-digit tier, an evident slip for "last 3", as every other tier reads.
Every chance is counted: all 10,000,000 possible numbers are checked one by one, and a second, independent calculation must give exactly the same. If a single figure differs, the page is not published.
