Strategy tips

  • A valid path contains exactly three distinct cells joined only by horizontal or vertical edges.
  • Track the running equation above the board and clear the path before the third number when the partial sum is already too large.
  • Keyboard players use arrows to move focus, Space or Enter to add a number, and Escape to clear the current path.
