The Inspiration & Problem I’ve always loved logic puzzles, but I noticed a recurring frustration with mobile versions of classics like Sudoku or Kakuro: the number pad. Constantly shifting your focus between the grid and a tiny keypad at the bottom of the screen breaks the "flow" state. I wanted to build something that felt tactile and seamless—a game where your concentration never has to leave the board. What is Star Logic? It’s a challenging, number-free logic brainteaser designed for fans of Star Battle, Sudoku, and Suguru. The goal was to take the elegant constraint-based logic of Star Battle and refine it into a smoother, more intuitive experience. By removing numbers entirely, we’ve eliminated the mental "math" fatigue and replaced it with pure spatial reasoning. Why you’ll love it: ->Zero Keypad Friction: Your finger stays on the grid. No more hunting for the "7" key. ->Pure Logic: No arithmetic or guessing. Every puzzle is solvable through deduction alone. ->Minimalist Design: A clean aesthetic that lets the logic breathe. ->Familiar but Fresh: If you enjoy the "boundary" logic of Suguru or the "inequality" feel of Futoshiki, this will feel like home—but with a twist you haven't seen before. I’d love to hear your thoughts on the difficulty curve and the "no-number" interface. I’ll be here all day to answer questions!
