## What is Helix Decode?

Decode corrupted DNA sequences in this elegant logic puzzle game.

  You are a gene engineer in a mysterious biolab. Your mission: repair broken DNA specimens
  by filling in the correct nucleotide colors. Every row and column must satisfy strict
  genetic constraints — no duplicate colors allowed.

  FEATURES

  • Pure logic gameplay — no guessing, no luck
  • Increasing difficulty from 3×3 grids to challenging 8×8 specimens
  • 6 beautiful color themes — from deep space to coral reef
  • Scanner tool to reveal hidden constraints
  • Undo system for careful experimentation
  • Entropy bar adds tension — too many errors and the specimen resets
  • Upgrade your lab with earned DNA Points: expand entropy capacity, unlock extra tools
  • Narrative events that unfold as you progress through specimens
  • Minimalist sci-fi aesthetic with dynamic DNA helix backgrounds

  HOW TO PLAY

  Tap an empty cell and choose a color. Each row and column has constraints that tell you
  exactly how many of each color should appear. Use logic to deduce the correct arrangement.
   Fill the entire grid correctly to stabilize the specimen and advance.

  Start simple. Think deeply. Master the helix.
