It sounds like you want to replicate their online "result checker". It would be relatively easy to create a spreadsheet where
- You type in the numbers from each entry. This would be 23 rows (and growing) by 8 columns? It looks like there are 5 main numbers, two special numbers, and a "raffle code".
- When the drawing is held, type in the winning numbers on a row
- The spreadsheet will highlight all the correct numbers and count how many were correct per entry and do whatever other special things Euromillions does (which I don't know) to determine a winner.
Is that what you are looking for? I'm not really sure how that lottery works so maybe there is more to it than what I wrote above. This would handle one drawing. If the same numbers are used for multiple drawings (it sounds like you can do that on their web site), you would need another set of rows to do each other drawing.
