How AI is used
This game was created by an independent developer. Generative AI tools were used during development to assist with programming, debugging, text editing, and the initial localization of Simplified Chinese, Traditional Chinese, English, Japanese, and Korean. All AI-assisted content was manually reviewed, edited, and approved by the developer. The game does not use generative AI to create content during gameplay, and player data is not used for AI training.

About Minesweeper Online
Minesweeper Shouldn’t Be a Solitary Game
Race against other players, solve a shared board together, or join the entire community in clearing a persistent world made of 336 massive regions.
Whether you are learning Minesweeper for the first time or chasing faster 3BV/s records, you can find your own way to play.
Clear a World Together
The Expedition World consists of 336 persistent regions, each containing a massive 512×512 board.
Every safe tile revealed by a player contributes to the same shared world. Explore the map, choose a region, coordinate through chat and map markers, and watch the world gradually change through the efforts of the entire community.
Complete regions to earn rewards, take part in community milestones, and leave your mark on a world too large for any single player to clear alone.
Race on the Same Board
Everyone receives the same board. The countdown ends—and the race begins.
Speed, accuracy, route planning, chord efficiency, and risk management all affect the final result. Finish the board as quickly as possible and compare your performance with every other player immediately after the match.
Play casual races or enter ranked competition to test your consistency under pressure.
Cooperate on One Shared Minefield
Invite 2–8 players to solve the same board together in real time.
Every reveal, flag, and mistake is synchronized. Divide the board, follow your teammates’ progress, recover from errors together, and experience Minesweeper as a true cooperative game.
More Than Completion Time
The game tracks detailed performance statistics, including:
- 3BV and 3BV/s
- IOE efficiency
- Completion time
- Click and chord performance
- Personal records
- No-Guess boards
- NoFlag challenges
Learn advanced techniques through the tutorial, then refine them across different modes and difficulties.
Progress, Compete, and Personalize
Complete daily and seasonal tasks, improve your rank, unlock achievements, and collect cosmetic rewards.
Customize your appearance with different avatars, cursor effects, flags, board themes, and other visual items—then show your style during multiplayer matches and world exploration.
Play With Friends
Create a party, join public or private rooms, chat with other players, and use optional voice communication while playing.
Whether you want a quick match, a coordinated cooperative session, or a long-term community expedition, there is always another board waiting.
