Soonsak: Offline Puzzles

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.
