About Sudoku online with friends

Sudoku online with friends - about the game
Sudoku Online with Friends

Get ready for a battle of wits where every move is a challenge. Forget the boring solitude of classic Sudoku! Sudoku Online with Friends is not just a game, it's a duel of intellects with real opponents, where only one can emerge victorious.

The Mystery of Numbers and the Magic of Cells

Your mission: fill the mystical 9x9 grid with numbers from 1 to 9. But be careful: here you are not just solving a puzzle, you are fighting for each cell with your opponent. Keep an eye on the time so you can make your move before the sand runs out.

Key rules:
  • The Law of Harmony: Each row, column, and 3x3 square is a sacred space where all numbers must be unique. If your move is incorrect, a small red number will appear in the cell — an error mark that both players will see. You will not receive any points for such a move.

  • Cell Awakening: You will receive 1 point for each correctly revealed empty cell. But the true power is hidden in the Black Square keys. Reveal all eight numbers in one of the lines (horizontal, vertical, or 3x3 block) to awaken the key and get +10 points. This is not just a bonus, but your path to domination!

  • Race to Triumph: Victory goes to the first player to score 50% of all possible points. This is a race where every point is worth its weight in gold!

  • Bets and Victory: Before the game begins, each of you places an equal bet with your SUDOKU coins, forming a common bank. The winner takes all!

  • Elo Rating: True masters seek not only victory, but also recognition. That is why the Kingdom has an ancient system of  Elo Master Rating. After each duel, your rating will change depending on the outcome:

    • A victory over a stronger opponent will bring you a large increase in your rating, while a loss will only result in a small decrease.

    • Conversely, a victory over a weaker opponent will earn you few points, while a loss can be very costly.

    • In this way, your rating will reflect your true skill and intellectual strength.

Secret Notes and Cascades rule

Use your hidden talents to outsmart your opponent. Transfer your assumptions and accurate guesses to Notes. Simply move the number to the cell and click “Check”. The small green number in the cell will be visible only to you.

Get ready for magic! When you solve the last number in a row, it can open by itself, as if by magic! What's even more amazing is that if this event triggers the opening of new blocks, they will also fall one after another, like a waterfall. Use this power wisely, because in one move you can break several seals at once and get a lot of points, which brings you closer to victory.

Young Padawans from the Steam universe get a head start - +1000 SUDOKU coins added to their base account.

Can you calculate your opponent's actions, find the right solution in the allotted time, and take the whole prize? Show who is the real Master of Numbers!
