Gridline: Logic Puzzles
DownloadGridline: Logic Puzzles brings the timeless challenge of newspaper logic games into a single, serene Android application. Designed for clarity and focus, every puzzle is generated specifically for your device screen and guarantees exactly one solution. You will never be forced to guess your way through a level because the entire grid can always be solved using pure logic alone.
This makes it an ideal companion for commuters or anyone seeking a calm, screen-free anxiety experience during their daily routine. The app features four distinct puzzle types, each available in three difficulty levels to suit your skill. Nonogram, known by many names like Picross or Paint by Numbers, challenges you to reveal hidden images using numeric clues.
Killer Sudoku, or Sum Sudoku, adds a mathematical twist to classic 9x9 grids with cages that must sum to specific totals. Binairo, or Takuzu, requires filling grids with zeros and ones while avoiding triplets and ensuring unique rows and columns. Futoshiki, or Unequal, tests your ability to place numbers correctly while satisfying inequality signs.
A unique feature is the Daily Puzzle, which offers the same challenge to all players, encouraging a shared community experience and a streak to maintain. If you get stuck, hints are provided not just as answers but as educational tools that explain the logical technique used or point out your mistake.
