LOGICA Puzzle: Logic Grid Game

Every puzzle is solvable by pure logic—no guessing, always one answer. From a gentle 3x3 to a fierce 6x6, with a fresh daily puzzle and a new one every time you play.

Read the clues, one at a time. No guessing required. LOGICA Puzzle is a logic grid game where every puzzle is built to be solved by reasoning alone—and there is always exactly one answer. It takes the classic pen-and-paper logic puzzle (the "Einstein's riddle") and turns it into something quiet you'll want to return to every day.

WHAT WE PROMISE

• Every puzzle is solvable by pure deduction. No luck, no guessing.
• The answer is always unique—follow the clues without contradiction and you'll reach it.
• Puzzles are generated fresh each time you play, and the same one won't appear twice in a row. Every round is new.

FEATURES

• Four sizes: 3x3 (gentle), 4x4, 5x5, and a tough 6x6. The bigger the grid, the deeper the deduction.
• Six themes: People, Animals, Fantasy, Space, Cafe, and Mystery—each with its own flavor.
• Daily puzzle: one shared puzzle every day. Build a streak and make it a habit.
• Records: solved count, day streak, average time, and no-hint clears—plus per-theme and calendar views.
• Stuck? Reveal a single cell with a hint, and learn the rules with an interactive tutorial.
• Feels good: haptic feedback the moment you solve, and emoji result sharing.
• Easy on the eyes: a calm indigo design with full dark mode.
• Fully offline: play anywhere, no connection needed.
