Sudoku is a single-player puzzle game, but it can be turned into a fun competition too! Join the Sudoku tournament and strive to reach the top.

While the tournament is running, you can collect points for any Sudoku you play, regardless of its difficulty. However, the harder the puzzle and the quicker you solve it, the more points you earn. The puzzles you fail to complete are also accounted for, even if the points you receive for these are minimal. The top three players at the end of the competition receive trophies to congratulate them on their success.

May the God of Numbers and Sudoku grids be on your side -  good luck and good work!

How are the tournament scores calculated?

While the tournament is on, you will automatically receive points for all the Sudoku puzzles you play. Uncompleted puzzles are also accounted for, to ensure no player is penalized for trying to improve their skills and play harder difficulty levels.

The tournament points are calculated as follows:

POINTS = BASE_DIFFICULTY_POINTS x PCTG_COMPLETION_MULTIPLIER x HINTS_PENALTY x ERRORS_PENALTY x VICTORY_MULTIPLIER

Formula explanation

BASE_DIFFICULTY_POINTS:

DIFFICULTY BASE POINTS
Kids 4x4 20
Kids 6x6 50
Very Easy (App only) 25
Easy 100
Medium 150
Hard 200
Evil 250
Impossible 300

 

 

 

 

 

 

 

PCTG_COMPLETION_MULTIPLIER: 

 

Board Completed MULTIPLIER
Yes 1
No Cells correctly filled / Empty cells x 0.5

HINTS_PENALTY: Each hint removes 10% of points (1 − HINTS x 0.1). The value can never be less than zero.

ERRORS_PENALTY: Each error detected using the “Check for solution” option removes 5% of points (1 − ERRORS x 0.05). The value can never be less than zero.

VICTORY_MULTIPLIER: Uncompleted puzzles = 1. Otherwise: 

VICTORY_MULTIPLIER = TIME_MULTIPLIER x PERFECT_GAME_BONUS x DAILY_GAME_BONUS

Calculating the victory multiplier

TIME_MULTIPLIER: The time multiplier uses a cubic bezier of 2 at 0 seconds and 1 at max time or above. This makes the time multiplier decrease faster at the start of the game and slower as time passes. In other words, the players are not penalized for taking longer than the max time to solve the puzzle, but receive a bonus if they solve it faster.

The max time changes according to the difficulty of the puzzle:

DIFFICULTY  MAX SECONDS   MULTIPLIER AT 1m   MULTIPLIER AT 3m 
Kids 4x4 213 1.3 1.01
Kids 6x6 591 1.56 1.28
Very Easy (App only) 238 1.34 1.03
Easy 1060 1.67 1.44
Medium 1381 1.71 1.51
Hard 1800 1.74 1.56
Evil 1899 1.75 1.58
Impossible 1931 1.75 1.58

The maximum times were defined based on thousands of games completed on our website and mobile app.


PERFECT_GAME_BONUS: A game without a single mistake gives 20% bonus points (1.2)

DAILY_GAME_BONUS: Daily games award 20% bonus points (1.2)
