Ninja Minesweeper

Ninja Minesweeper is a minesweeper puzzle adventure: classic minesweeper logic with no guessing, turned into a ninja infiltration of six fortresses in feudal Japan. Every floor hides its traps: spike pits under the boards, tripwires strung with bells, jars packed with black powder. Read the numbers, plant a kunai on every trap, and walk out the way you came in.

The moon is up over the Mountain Dojo. The guards are asleep, the floorboards are not. You step onto the glowing lantern, the floor opens around your feet, and the first number tells you how many traps touch that tile. One room at a time, one storey at a time, you climb toward the captain at the top.

Six fortresses, 108 levels
• The Mountain Dojo, the Bamboo Stronghold, the River Castle, the Ashen Temple, the Oni Keep and the Shogun's Palace.
• Every fortress is a painted climb of 18 storeys, and each one adds its own rule.
• Paper screens that hide their numbers. Great jars that count twice. Smoke numbers that see only straight ahead. Oni eyes on the walls that count a whole row.
• Every room has a way out: a gate, a captive to rescue, sealed orders to steal.
• The last floor of each fortress is the captain's. Pin every guard, then face him.

Never a guess
• No guess minesweeper: every campaign room and every Daily Room can be cleared by reading alone.
• No coin flips at the end, no lucky last click. If you are stuck, the numbers still have the answer.
• Classic minesweeper boards too: Beginner, Intermediate and Expert, for purists.

Move like a ninja
• Your ninja walks the floor: you can only step beside tiles you have opened.
• Three armour plates: touch a trap and a plate breaks, not the room.
• Plant a kunai on a trap, then sweep around a finished number in one move.
• Candle rooms: reach the way out before the light goes dark.

Three ninja tools
• Smoke Bomb opens the 3 x 3 around a tile and marks its traps.
• Shuriken strikes one covered tile: marked if trapped, opened if safe.
• Sixth Sense shows the next sure step, or a kunai you planted wrong.

Stars, Ghosts and the Shinobi Densho
• One star for the way out, one for beating par, one for a clean run.
• Pin every trap without touching one and without a tool to earn the Ghost stamp.
• Hidden scrolls fill the Shinobi Densho, a book of 24 ink-wash pages of ninja lore.
• Complete a fortress's pages to unlock a new floor, kunai or garb.

A Daily Room
• One new room every day, the same for every player.
• A daily goal on top, a streak to keep, and month badges for the rooms you win.

Koban, rank and the Armoury
• Every room pays koban. Rise from Ashigaru to Daimyo, and your rank never falls.
• Spend koban in the Armoury on ninja tools and looks: Jade, Bone and Gold kunai, cedar, bamboo, iron and gold lacquer floors, and the Snow Garb.
• Every look can also be bought outright, and packs of tools keep your pouch full.
• The Ember Timber and White Keep floors, the Six Fortresses wallpapers and the Patron of the Shadows are sold on their own.

For grown-ups
A quiet, sharp logic puzzle for adults who like to think before they step. Painted fortresses, ink-wash lore, real traps and a captain waiting at the top.

Every floor hides its traps. Every trap can be read.
