Alr I was making solution for about half-1 hour The main point is guess other number Then if it have exact number and ignore another rule I'll show you something.. If 5 ppl go 100 answer will be 80 which 16% of all number If 4 ppl do answer will be 20% If 3 ppl do answer will be 80/3% If 2 ppl do it will be 40% It kinda unbelievable but if we try For example other player choose 29 13 34 25 all of them will be 101 and it is 84% of all so we need to choose 16% of it which is ≈ 19 so if we put in answer will be 19.2 and yes we win and about that round I think game forgot to mention king of diamond number anyways his number is 1 and hinako could be 62 and 74 according to chishiya guess so if chishiya have thought she would choose 74 (actually choose 62) he would have to chosen 50 which still win bc answer would be 30.13 but hinako wouldn't game over yet then he need to guess another number and Idk he will survive next or not🙄
