Idea for a sudoku tournament type

Everyone has a set time to solve, the sudokus come one after the other, before each sudoku you can choose which difficulty you want to solve. There are unlimited sudokus during this time. You get a certain number of points for each difficulty level. The one who collects the most points wins. I suggest 40 minutes for the time, based on tournament experience so far, it seems that people tend to get tired and it also starts to hurt their eyes. The points you can get could be 2 3 5 8 depending on the difficulty level.

I'm waiting for Tiit's comment on this. The idea was to make online sudoku tournaments as similar as possible to those that take place in real life.

The only flaw in the idea: If no matter how many sudokus are given, it probably assumes that everyone has different sudokus. This makes solving unequal. Another option is to generate a set of sudokus in advance (this set must be quite large - easy 70, medium 60, difficult 50, very difficult 40 (time 40 minutes - and this option does not allow the option to give up)). And then they should be given to everyone in a certain order. However, there is still a moment of inequality if the first difficult sudoku to be solved happens to be harder than the very difficult one. The one who chooses the very difficult ones to do gets an advantage (and vice versa). In short, the idea of the previous story is that in my opinion there should be a set of sudokus that must be done and if you can do it faster, then even faster. (However, it is not so much that everyone should be able to solve it in the same time) The second flaw was already described a little in the text of the first flaw. Should it be possible to give up? Should we give minus points for it? If giving up is possible, then there is no point in generating sudokus in advance, let them be generated on the spot. This comes with the disadvantage that people will start choosing ones that seem easier. If you still give minus points, it will be a mess if you come across some really bad sudoku that you can't beat. You have to sacrifice either points or time. The idea is interesting, but it's not quite a normal sudoku tournament anymore (in a real tournament I choose another sudoku and do it, no one will take points away from me for that). The advantage is that the tournament doesn't take very long and therefore the user doesn't get tired so much. And everyone has to tire themselves out the same amount. Another advantage is that there is no time limit for each sudoku. Everyone manages to complete a certain number of sudokus. At the same time, I don't consider the fact that there is a time limit a big disadvantage. After some practice, all these times can be exceeded.

I don't see a big problem with the fact that the competition is not completely fair/equal, in other games too the final order is often determined by, for example, which opponents were encountered when, in card games one player is likely to win from the start. To avoid giving up because of this, in order to get an easier sudoku, you can make it so that you have to solve for at least 1 minute before giving up. One difference and also a disadvantage compared to reality is that the current tournament system has a separate time control for individual sudokus. There should be a time limit for solving all sudokus, then those who cannot solve the easiest one in 5 minutes can also participate.

I actually really like this point. In order to give the same sudokus exactly, the best ones compete against time. Whoever doesn't finish gets points. It would probably make sense to solve them sequentially, so you can't start with the hardest one. (This nuance is probably not a big minus)

Idea: It would be possible to solve the problem in such a way that all sudokus would have a 2x longer time control, but the total time would still be 1h 40min (you can make it smaller if necessary). If you don't make it to the end, then after a certain time the tournament would be ended and those sudokus that have already been solved would be counted. To make the order clearer, you could also count the squares filled in the last sudoku. One assumption would probably be that you can't give up. That you have to do as many as possible. Otherwise, calculating the points would be difficult. PS: Another option for explaining the order is that if several players reach, for example, the 5th sudoku, then the one who did the first 4 fastest wins. PPS: Or give each sudoku 1h 40min to solve - the time elapsed since the start of the tournament. - A big plus with such a thing would be that everyone would finish their sudokus, which they do at least. Currently, many people don't do any.
