Logidoku: Brain Puzzle Live

Three puzzles, one daily brain workout. Place the cats on a colorful grid, fill the numbers in Sudoku, and solve a fresh Math Crossword every day. Logidoku is made for short, focused sessions: a morning warm-up, a coffee break, ten quiet minutes before bed. Every puzzle has exactly one solution, and you reach it with logic, not luck. CAT PUZZLE: ONE RULE, ENDLESS LOGIC Put one cat in every row, every column and every color region. The catch: no two cats can touch, not even diagonally. You learn the rules in a minute, then the grids grow bigger and the regions trickier. This puzzle trains the skill of ruling things out and seeing the whole board at once. SUDOKU: THE CLASSIC PLUS FOUR TWISTS Fill the 9×9 grid so every row, column and 3×3 box holds the numbers 1 to 9. Start with relaxed grids and work up to puzzles that make you stop and think. Sudoku trains number patterns, focus and patience. Know the classic by heart? Try the variants. Each one adds a single new rule that changes how you solve: - Asterisk: the 9 cells that form a star shape must also hold 1 to 9 - Center Dot: the center cells of all nine boxes must also hold 1 to 9 - Windoku: four extra shaded 3×3 windows must also hold 1 to 9 - Consecutive: marks between cells show which neighbors are consecutive numbers, like 4 and 5 MATH CROSSWORD: A NEW PUZZLE EVERY DAY Every day brings one new crossword made of equations. Fill in the missing numbers so every equation, across and down, is correct. It takes a few minutes and keeps your mental math in shape. Solve a puzzle each day to reveal the picture of the month and earn rewards along the way. WHY MIX IT UP? Doing the same puzzle every day turns into routine. Switching between shapes, number grids and equations makes your brain work in different ways. When one mode feels easy, another one keeps you sharp.
