## What is Soonsak?

Five puzzle games that work in airplane mode. 
Soonsak is Korean slang for time that vanishes in a blink.

Soonsak puts BoomDoku, Minesweeper, Sudoku, Nonogram and Metro Link in one app. 
Tap a game card on the home screen and the board opens right away. 
Nothing needs the internet, so it plays the same on a plane or a subway, with no ads and no login.

FIVE GAMES
- BoomDoku: a logic puzzle where each colored area holds exactly one Boomchi. One per row and column too, and no two touching
- Minesweeper: read the numbers and dodge the hidden mines. Stepping on one costs a life
- Sudoku: 1 to 9 in every row, column and box, from easy 6x6 boards up to hard 9x9
- Nonogram: paint cells from number clues to finish a picture. Boards from 5x5 to 12x15. The 62 hand-drawn pictures come first, in order, and difficulty starts to mix at level 68
- Metro Link: join stations of the same color with lines and fill the whole board. Lines never cross

LEVELS THAT NEVER END
- Every game has its own level that keeps climbing. Clear a board and you move on to the next level
- Your level sets a difficulty ceiling. The ceiling rises from the easiest step up to Master, and BoomDoku adds a 10x10 Legend step from level 121 (it shows up once early, as the level 100 challenge board)
- Past the first step, each board's difficulty is mixed. The ceiling comes up most often, with boards one or two steps below in between
- Every 10th level is a challenge board at the ceiling
- Steps you have passed stay open as practice boards

DAILY BOARD AND STREAK
- One board a day per game, the same for everyone
- Clearing a single board keeps your streak going, shown on a calendar and as streak badges
- The Records tab shows boards cleared and best times for each game

SOONSAK TAG AND NIGHT GREETING
- Match or beat your best time for a difficulty and the result screen shows a "Soonsak!" tag
- From 10 pm until 5 am the home screen greets you with "One more tonight" and a few stars and a crescent moon

COLLECTIBLES
- Every 5 levels you clear earns a collectible: stickers of Boomchi, Menchi, Dandi and Yenchi, Seoul landmark stamps and line badges
- BoomDoku and Minesweeper have 32 collectibles (up to level 160), Sudoku 42 (up to level 210) and Metro Link 55 (up to level 275)
- Clearing level 50, 100, 200, 500 and 1000 in a game earns a milestone badge
- Finished Nonogram pictures go into a picture album

WHEN YOU GET STUCK
- A hint tells you where to look and why, in one line
- Undo and erase are always there
- If you use up all three lives, keep what you placed and get fresh lives to continue
- Rules are shown on your first board and can be opened again in Settings

SETTINGS
- Sound, haptics, color-blind patterns (a pattern drawn on each color), and language (auto, Korean, English)

PRIVACY STAYS ON YOUR DEVICE
No account, no server. Progress and settings are stored only on your device, and there are no ads or analytics tools. Sound effects are made on the device, so everything works without the internet.
