One laser enters vertically downward while the other is initially horizontal from the right.
You have 5 mirrors, each of which can deflect a beam at either 45° or 135°.
Each laser beam passes through all targets only once.
Each segment of one laser beam passes exactly through 1, 2 and 3 targets
while those of the other never pass through more than two.
You may care to challenge yourself by fitting all targets into a 4 x 4 grid.
As a further challenge fit the 6 targets into a 4 x 4 grid, use the same rules but use only 4 mirrors.
Note: 1. Brian Smith's Laser Puzzle was the inspiration for this.
2. I acknowledge Brian Smith's thoughts re the use of a 4 mirror version.
re(2): 4 mirrors, 5x5 grid - profession??
