Chain 3+ to build combo. Consecutive long chains increase the multiplier.

Features

  • 6x6 grid filled with random numbers 1-9
  • Draw chains through adjacent cells (orthogonal and diagonal) with strictly ascending numbers
  • Chain scoring: length squared, multiplied by combo bonus
  • Combo system: consecutive chains of 3+ build a multiplier up to x5
  • Gravity physics: used cells disappear, remaining cells drop down, new numbers fill from top
  • Two game modes: Timed (90 seconds) and Zen (no timer, ends when no valid chains exist)
  • Drag-to-connect path drawing with mouse or touch
  • Visual chain trail with connecting lines and highlighted cells
  • Live chain preview showing potential score before releasing
  • Distinct background color per number value for easy scanning
  • Score popups, combo bar indicator, and best chain tracking
  • Best score saved per mode in local storage
  • Responsive design that works on both desktop and mobile

How to Use

  1. Select a game mode: Timed (90-second countdown) or Zen (play until no chains remain).
  2. Click and drag (or touch and drag on mobile) across adjacent cells to form a chain of ascending numbers (e.g., 1 → 2 → 3 → 4).
  3. Cells can connect in any direction: up, down, left, right, or diagonally.
  4. The chain preview at the top shows your current chain and its potential score before you release.
  5. Release to submit the chain. Chains must have at least 2 numbers.
  6. Scoring: chain length squared, multiplied by your current combo multiplier.
  7. Build combos by making consecutive chains of 3 or more links. The multiplier resets if you make a short chain.
  8. After a chain is submitted, used cells disappear, remaining cells drop down with gravity, and new numbers fill in from the top.
  9. Your best score per mode is saved automatically.
