Instruction
To solve the nine-dot problem, it
is recommended that you follow these instructions:
- Print out this page or write down 9 dots on a blank paper
- Without lifting your pencil from the paper, draw exactly four straight, connected lines
that will go through all nine dots, but through each dot only once.
- After you have tried two (2) different ways, ask yourself what restrictions you have set
for yourself in solving this problem.
