Quill & Star: Logic Puzzle

Quill & Star is a daily Star Battle logic puzzle, set like a page from a well-made puzzle book. The rules fit in one line: place one star in every row, column and region, and never let two stars touch, not even at the corners. Every puzzle has exactly one answer, and you can always reach it by reasoning. No guessing. One puzzle every day Everyone gets the same daily puzzle on the same date. Monday starts gentle on a 6×6 grid, and the week builds to a fiendish 10×10 on Sunday. Missed a day? Open the calendar and play it later. When you’re done, share a spoiler-free result with friends. Simple rules, pure deduction Tap a cell once to cross it out and twice to place a star, or drag to cross out several cells at once. Stars that break a rule are ringed in red. There’s no time limit, and you can hide the clock. It’s the classic pencil-and-paper brain teaser, and if you like, each star you place crosses out the cells that can’t hold one. Hints that explain the next step Stuck? A hint points at the cells that matter and tells you why, in plain words: “Row 3 has only one open cell left, so its star goes there.” Read it and carry on, or tap Show me to make that one move. A hint never gives away the whole puzzle. An endless puzzle book Beyond the daily puzzle, the puzzle book keeps going. Grids grow from 5×5 to 10×10 and from Gentle to Fiendish, with an easier breather every few puzzles. Puzzles are made on your device, so the book never runs out. Streaks, a calendar and a daily reminder Solve today’s puzzle to grow your streak. The calendar marks the days you’ve solved and keeps your longest streak. Miss a day, and a short ad earns a streak freeze that saves it. Choose a time for a daily reminder, or leave reminders off. Made to be read Play in the paper edition or the night edition, or let your device decide. Every region has a printed pattern as well as a color, so you never rely on color alone. Text follows your device’s font size, animations calm down when your device asks for less motion, and sounds and vibration are optional. Fair ads Quill & Star is a free brain game supported by ads. No ad ever interrupts a puzzle. Your first three puzzles come with no ad breaks, and the first three puzzles in the book come with free hints. After that, a short ad may play between puzzles, and a small banner sits at the foot of the menu pages. Rewarded ads only play when you ask for one: for a hint, for one more try after three mistakes, or for a streak freeze. If an ad can’t load, you get the reward anyway.
