Tametsi

What Is Tametsi?

Tametsi is a number-logic puzzle where you locate all hidden mines on a grid using regional number clues — not just adjacent-cell counts.

Every revealed number tells you how many mines are hidden in a defined region. Regions can span the entire board, wrap around edges, or form irregular shapes.

Every puzzle on this site is guaranteed solvable by pure logic — no guessing required.

How to Play Tametsi

1. Left-click a cell to reveal it and see its regional mine count.
2. Right-click a cell to plant a flag (🚩) on a suspected mine.
3. Hover over any revealed number to highlight the region it counts.
4. Use number clues to deduce which cells are safe and which hide mines.
5. Win by correctly flagging every mine and revealing every safe cell.

Tametsi vs. Minesweeper

• Regional clues: Numbers count mines in a defined region, not just the 8 adjacent cells.
• No guessing: Every puzzle is fully logic-solvable — no 50/50 guesses.
• Irregular regions: Clue regions can be any shape, not a fixed 3×3 neighbourhood.
• Wrapping boards: Some grids have edges that connect, opening new deduction paths.
• Fresh daily puzzle: A new guaranteed-solvable challenge every day at midnight UTC.

Tametsi vs. Tentaizu

Both Tametsi and Tentaizu are regional mine-finding puzzles, but differ in key ways:

• Grid size: Tametsi uses larger multi-row grids; Tentaizu uses a compact 7×7 grid.
• Mine count: Tametsi has many mines across a large board; Tentaizu hides exactly 10.
• Difficulty tiers: Tametsi offers Beginner, Intermediate, and Expert modes.
• Reveal vs. cycle: In Tametsi you reveal cells; in Tentaizu you cycle cells through states.

Tametsi Strategy Tips

1. Start with fully constrained regions. If a region's mine count equals its hidden-cell count, flag them all.
2. Spot zero regions. A region showing 0 means every hidden cell in it is safe — reveal them all.
3. Subtract overlapping regions. The difference in counts between overlapping regions constrains their unique cells.
4. Hover to visualise. Hover any number to see its region and find overlaps with neighbours.
5. Flag early. Confirmed mines flagged promptly shrink the unknowns in every overlapping region.
6. Work inward. Smaller edge regions often yield the first sure deductions.
