Expert Tips
Fill the corners first: Corner cells can only be reached in limited ways — place those paths early to avoid painting yourself into a dead end.
Think about coverage: If a region of the grid can only be reached by one colour's path, that path must cover it — even if it seems like a detour.
Re-draw freely: There's no penalty for replanning. Drag over an existing path to erase and reroute it any time.

GOAL

Connect every pair of same-coloured dots with a continuous path and fill every single cell on the grid. Both conditions must be met to solve the puzzle.

RULES

  • Drag from a dot to draw a path. Paths must move through adjacent cells (no diagonals).
  • Paths cannot cross or overlap each other.
  • Dragging over part of an existing path truncates it at that point.
  • The puzzle is solved when all dots are connected and all cells are filled.

SCORING

Base points by difficulty (Easy 500 · Medium 1000 · Hard 2000). 30 pts deducted per move over par. Minimum score is 50.

Why this sharpens your mind

SPATIAL PLANNING

Routing paths through constrained space exercises the same neural circuits as navigation, route-planning, and multi-step problem solving.
