Minesweeper World Championship 2025

The Minesweeper World Championship 2025 will take place at 42 Madrid on the last weekend of September - for the first time in ten years!

Main Events

There will be three main events:

The Minesweeper World Championship 2025

The World Championship will use exactly the same format as previous world championships, ie, 0+5+5/3h.

As a brief explanation, this means that players play as many games as they like for three hours, and the sum of their five best intermediate and expert times is their final score - obviously, the lower the better!

It will be played on Scoreganizer using Vienna MineSweeper. The version used will support skins, and with that larger square sizes.

A more detailed explanation with examples is available on the info page for the World Championship 2015.

The Chord Cup

The next iteration of this modern (yet already venerable) PvP event series.

More details coming soon!

A note on L chords

The Chord Cup and Minesweeper Royale will support L chords; however, the Minesweeper World Championship will not, only L+R chords are supported.

This is because the World Championship operates under the ruleset of the official world ranking on minesweepergame.com.

If you haven't played with L+R chords before, we recommend getting used to that well before the tournament. If that is the case, odds are, you play on minesweeper.online - you can switch to L+R chords in settings.

Location

The address of 42 Madrid is:
