T-3 Mines is a number-clue clearing puzzle played worldwide, with our T-3 Neo™ hidden under the board. Each number tells you how many T-3 Neos touch it — read them, and open every square that is safe.

A cleared 6×6, its T-3 Neos flagged.

How it works

The board hides a set number of T-3 Neos, one at most to a square. The puzzle starts with its opening already open.

1

Eight neighbours

Each open square shows how many T-3 Neos are among the squares touching it — up, down, sideways and diagonally. A square on the edge has five neighbours, a corner three.

2

Open the safe squares

Tap a square you have worked out is safe. A square with no T-3 Neo beside it opens all its neighbours, and on. Tap a square holding a T-3 Neo and it blows up: that puzzle is lost, and you start a new one.

3

Clear the board

You win when every safe square is open. Flags are your own notes — flagging every T-3 Neo is not a win on its own. A flagged square shows a red T3rminator: you have marked a T-3 Neo inside.

Playing

Switch between Reveal and Flag under the board. On a phone a long press flags a square and another long press removes the flag; with a mouse, right-click does the same — a left click never flags, it only opens. A flagged square cannot be opened by a tap until you take the flag off. Tap a number once you have flagged as many squares round it as it shows, and every other hidden square beside it opens at once — trust your flags: a wrong one makes that a lost attempt. Otherwise the tap just outlines the hidden squares it touches.

The promise, and its limits

Every puzzle has a safe, logical route from its opening: at each step at least one square can be proven safe, or proven to hold a T-3 Neo, from the numbers you can see. It does not mean any tap is safe — a hasty tap or a wrong flag can still lose.

Thinking it through, with pictures

Each example is a puzzle made by the game, before and after one idea. Every example was checked by the T-3 Mines engine.

Stuck? The T-3 Neos are there — but a shown puzzle does not count as solved, and neither does one after a lost attempt.
