Mineoku

A naval minefield logic puzzle for Android. Free on Google Play.

Chart the minefield by pure logic. Every board has exactly one solution, and you never have to guess: each mine can be found by careful deduction.

Pure logic, no guessing: an 8×8 board mid-solve, with mines placed and cells ruled out

Stuck? Send a drone: SURVEY explains the next logical step

400 levels to clear: the win splash over a cleared board

How it works

The board is split into colored regions. Place mines so that:

every row has exactly one mine,
every column has exactly one mine,
every region has exactly one mine, and
no two mines touch, not even diagonally.

Mark the cells you've ruled out with an X. But careful: put an X on a real mine and it goes off. You have three lives per board.

400 levels in five sectors

Each level is graded by the deductions it needs, so the challenge climbs steadily from the shallows to the deep.

Sector	Levels	Board
Shallow Waters	1–25	6×6
Coastal Patrol	26–100	7×7
Open Sea	101–225	8×8
Deep Trench	226–325	9×9
Abyssal Plain	326–400	10×10

Daily Sonar Op and Free Play

A new board every day, the same for every player, growing from 7×7 early in the week to 10×10 on Sunday, so keep your streak going. Or pick any size from 6×6 to 10×10 in Free Play for a fresh board whenever you like.

Help when you're stuck

Send a minesweeper to Sweep a mine into view, launch a Survey drone that shows and explains the next logical step, or Ping the board to clear a few safe cells. Helps never cost stars. Charges refill over time, and you can watch an optional ad to get one back sooner.
