Daily sudoku TOP

Good news for Sudoku solvers!

We have added a new feature to the sudoku room – summary of solved daily sudokus. This table shows today’s fastest sudoku solvers. Each solved daily sudoku gives you points which are calculated using the formula: 

(fastest time)*100/(your time)

So, the maximum points for each type of sudoku is 100 and the overall is 900 since there are 9 types of sudokus. The table also shows how many 1st, 2nd and 3rd places you have that day.

See you in the sudoku room!

Introducing Mindgame TOP

In addition to regular game standings (eg. chess standings or othello standings) we now have the “Mindgame TOP“. In short it reflects the best mindgame players in Mindoku.

It is calculated based on weighted ratings in five games: English Checkers, Chess, Gomoku, Othello and Sudoku. The weight of each rating is relative to the amount of players in specific game standings.

The formula of calculating the rating is as follows:

Rating = ((r1*num1) + (r2*num2) + … + (rN*numN)) / (num1 + num2 + … + numN)


  • r1, r2, …, rN – User’s rating in a specific game
  • num1, num2, …, numN – The amount of users in a specific game standings

How to get a mindgame rating?

Simple – you have to have a rating in each of the five games. If you haven’t already have a rating in each of the five games, go ahead and get it! 😉
