Connect the stars with lines, so that the number inside each star corresponds to the number of lines connected to it, and the number in each barrier corresponds to the number of lines intersecting it.
Note: The stars in the corners cannot be connected, since the lines would pass through other stars.

Move one of the Friends to the Exit Point.
PLAYING THE GAME:
Draw lines to move Friends. A move is connecting a point on the Grid to another point on the Grid by drawing a straight line. The line can be made in any direction, as long as it connects exactly two points and doesn’t cross or touch another line.
You move each Friend as many times as it says on the Timeline, starting with the topmost Friend and continuing in the order all the way down to the bottom one.
KEY POINTS, EXIT POINT, AND WALLS:
One of the Friends must move to the Exit Point, but before he does that, each of the Key Points must be already connected with a line. A Wall is a double line and no Friend can cross or touch it.

Circles are particles and lines joining them are bonds. The objective is to find all the hidden values, following these four rules:
- Particle values must be the sum of their bond values.
- Particles can have the following values: 0, 1, 2, 4, 8, 12, 16.
- Bonds can have the following values: 0, 1, 2, 4.
- If two particles have the same value, the bond between them must have value 0.
4. Chess Connect
by Puzzle Prime
The starting and ending positions of 6 chess pieces are shown on the board. Find the trajectories of the pieces, if you know that they do not overlap and completely cover the board.
Notes: The pieces can not backtrack. Two trajectories can intersect diagonally but can not pass through the same square. Only the Knight has a discontinuous trajectory.
