Star Battle Game Guide

📖 About

Star Battle is a spatial logic puzzle that challenges you to place stars strategically! Each row, column, and colored region must contain exactly two stars—but here's the catch: no two stars can ever touch, not even diagonally. This creates a fascinating interplay of constraints that requires careful deduction and planning. A perfect blend of sudoku-style logic and spatial reasoning!

🎯 Objectives

Place exactly two stars in each row, column, and colored region while ensuring no stars touch each other (including diagonally). Use logical deduction to find the unique valid arrangement of stars.

🎮 How to Play

Click cells to place stars. Each colored region needs 2 stars. Stars cannot be adjacent horizontally, vertically, or diagonally. Use logic to deduce valid positions.

⌨️ Controls

Click on a cell to place a star. Click again to remove it. Stars turn yellow when placed. Gray cells indicate positions made invalid by nearby stars.

⚙️ Game Mechanics

  • Each row must contain exactly 2 stars
  • Each column must contain exactly 2 stars
  • Each colored region must contain exactly 2 stars
  • Stars cannot touch horizontally, vertically, or diagonally
  • There is exactly one valid solution

Features

  • Visual Feedback - See which cells are blocked
  • Region Tracking - Know which areas need stars
  • Error Detection - Invalid placements shown
  • Multiple Grid Sizes - Various difficulty levels

💡 Tips

  • Start with small regions - they have fewer options
  • If a star is placed, mark all adjacent cells as empty
  • Regions with 2 stars in 3 cells are constrained
  • Work systematically through constraints

Frequently Asked Questions

Can stars touch diagonally?
No! Stars cannot touch in any direction, including diagonally. This is what makes Star Battle challenging—you must leave at least one empty cell between any two stars.
Where should I start?
Start with the smallest regions—they have the most constraints and often force star positions. Also look for rows or columns that are nearly complete.
What if I make a mistake?
Click on a placed star to remove it. Use the process of elimination—when a cell must be empty due to nearby stars, it helps narrow down where stars can go.
Is guessing required?
No. Like all good logic puzzles, Star Battle can be solved entirely through logical deduction. If you're guessing, you may have missed a constraint.
