Drag the dots to change the arrangement of the lines, then compare your result with the pattern shown above the board. Finding the solution requires careful observation and an understanding of how each movement affects the complete shape. The puzzles begin with straightforward arrangements before introducing more detailed designs that require additional planning. If a move does not work as expected, use the undo or reset controls to try a different approach. Hints are also available when you need some guidance. Features: • Move connected dots across a grid • Recreate the target shown in each level • Solve a sequence of spatial pattern puzzles • Undo individual moves or reset the board • Use hints when you need assistance • Progress through increasingly detailed arrangements • Play with simple drag controls Examine the connections, consider each position, and discover how to form every pattern.
