Frequently asked questions
How do I flag mines on a phone?
Toggle the Flag button and taps place flags instead of opening cells. On desktop, right-click flags as usual.
What is chording?
Clicking an already-open number whose flags equal its value opens all its other neighbors at once. It is the main speed technique, and it will detonate if your flags are wrong.
Can the first click ever be a mine?
No. Mines are placed after your first click, excluding that cell, so every game starts with information.
What are the standard board sizes?
Beginner is 9x9 with 10 mines, intermediate 16x16 with 40, expert 30x16 with 99, the same layouts as the classic Windows versions.
