Hex Mine· Advanced

Goal

Win by uncovering every target cell (mint) hidden in the hex grid. Use only the visible number clues to logically deduce which gray (?) cells are targets and which are excluded. Every puzzle is designed to be solvable by pure logic — no guessing needed.

Rules

  • Use the round button at the bottom-right to switch modes. The mint circle is target-finding mode; the dark-gray circle is exclude-marking mode.
  • ?Tap a gray '?' cell to reveal it under the current mode. Tapping with the wrong mode adds one mistake (5% penalty) and leaves the cell gray.
  • NA revealed cell's number counts the target cells among its 6 neighbors. Each hex has neighbors in 6 directions: N, NE, SE, S, SW, NW.
  • {N}When a number is wrapped in braces as {N}, the N target cells among the neighbors form a single contiguous block.
  • -N-When a number is wrapped in dashes as -N-, the N targets are split into 2 or more separated blocks, with at least one excluded cell between them.
  • ↕Numbers on the grid edge count targets along the entire axis line (vertical or diagonal). The same {N}/-N- continuity rules apply (advanced).

How to Play

These diagrams show how the 6 neighbors around a center cell can be arranged. The same count can be a {N}, -N-, or plain number depending on the layout.

3
{3} — 3 targets form one contiguous block
3
-3- — 3 targets are split into separate blocks
2
2 — among gray neighbors, 2 are targets (positions unknown yet)

Tip

  • Don't guess. Every puzzle is designed to be fully determinable from the currently visible numbers alone.
  • Start with 0 or the maximum (e.g. 6). A 0 instantly excludes all neighbors; a maximum makes them all targets.
  • Stuck? Tap the 💡 hint — it pulses the next cell that can be logically confirmed from the current information.

Hexagonal logic puzzles engage constraint-based reasoning and working memory, both linked to fluid intelligence training.
