In general, there is a game like "Quiz" and naturally it was necessary to connect the rating, connect the Google Play rating, so the bad luck is that the rating on Google Play can only be increased, but not reduced. How can I choose the best player for the type of game "Quiz"?

I thought to do so, if a person answers correctly +1 point, if not, then -1 point, and in such a situation that the Google Play rating can not be reduced, just add, how can I identify the best? Simply, if we add to the rating only for the correct answers, then it will not be an honest rating, in the first place will be the one who will simply have more correct answers, disregarding the wrong ones, even though he will have wrong answers more than correct ones, then he It will still be on the first, how to solve this in Google Play ? Or do you need to do your rating on the server?

    1 answer 1

    The correct answer is 1 point. Wrong answer 0. Why reduce for the wrong answer?

    You can make the following option - the rating depends on the rating of the players who gave the answer. For example, if a player with a high rating gave the correct answer, then a lower rating is added to him than a player with a small rating for the same answer. That is, if a player simply tries to guess, then his rating does not increase, while for the rest he grows.

    • so it will be the wrong rating, as I wrote above, in the first place will be the one who answered the most, and not the one whose difference between correct and incorrect answers is greater. - Iman
    • a person can just then poke at the answers and sometime the correct answer will come out, and so get points, and the rating doesn't make any difference to the wrong answers. - Iman
    • let's not change the answer. make more answers. guess one of the two - 50%. one out of ten - 10%. guess will be much harder. plus you can use an adaptive rating - each subsequent correct answer brings more points. - Mikhail Vaysman
    • I have 4 possible answers, but you need to think about adaptive rating, and it’s impossible to make a rating using Google Play options that would take into account correct and incorrect answers? - Iman
    • updated answer. added an idea with a relative rating. - Mikhail Vaysman
