The most frustrating moment in Minesweeper is a coin-flip guess at the end of a good game. The daily Minesweeper on Everyday Games is built so that never happens: every board can be cleared by logic alone.
How the daily board works
One 16×16 board with 40 mines each day, the same for everyone.
It opens with a safe area already uncovered, so you never start blind.
Before a board is used, a solver checks that it can be cleared from that opening without a single guess.
Hit a mine and you can try the same board again. Clear it to keep your daily streak going.
Patterns that solve almost everything
A 1 touching only one hidden square: that square is a mine.
A number whose mines are all flagged: every other square around it is safe.
1-1 against a wall: the square past the second 1 is safe.
1-2 against a wall: the square past the 2 is a mine.
When two numbers share squares, compare them: the extra squares around the bigger number hold the difference.
Controls
Tap a square to dig, or switch to Flag to mark mines; long-press also flags. Tap a number whose mines are all flagged to open everything around it at once (chording), which saves a lot of taps.
More Minesweeper
For classic games there are Easy (9×9), Medium (16×16) and Hard (16×30) boards with a safe first click. Those are random, so a late guess can still happen there; the daily board is the one that never needs one.
