Lunoku vs Binary Puzzle

A fresh logic puzzle every day — the same one for everyone, everywhere. Fill the grid with suns and moons using three simple rules, keep your daily streak alive, and finally understand the game with hints that explain the why, not just the answer. Lunoku is a binary logic puzzle, also known as Takuzu, Binairo or the sun-and-moon Tango game. Guessing is never required: every daily puzzle has one unique solution you can reach with pure reasoning. It is the calm morning ritual for anyone who loves sudoku, nonograms and a genuinely good brain teaser. HOW TO PLAY Fill every cell with a sun or a moon under three rules: - Never three suns or three moons in a row, in any line or column. - Each row and column holds the same number of suns and moons. - No two rows are identical, and no two columns are identical. Tap a cell to cycle through empty, sun and moon. Long-press to lock a cell you are sure about so you never disturb it by accident. ONE PUZZLE A DAY - The very same challenge for the whole world, generated from today's date. - A gentle weekly curve: 6x6 grids Monday to Thursday, 8x8 on Friday and Saturday, and a bigger 10x10 special every Sunday. - A discreet timer, your personal average and how today compares the moment you finish. BUILD YOUR STREAK - Light your streak by solving the puzzle every single day without missing one. - A monthly calendar shows every day you have solved, with today clearly marked. - Missed a day? Unlock it from the archive and catch up whenever you want. HINTS THAT TEACH YOU This is what makes Lunoku different from other binary puzzles. Every hint fills a cell you could have deduced and explains the exact rule in one short sentence — "you can't have three moons in a row here" or "this line already has all its suns, so the rest must be moons". You learn the technique, not just the solution, and soon you will not need hints at all. ENDLESS PRACTICE Want more than one a day?
