Tips to help you find the 67

If you’re struggling, don’t worry—it’s tricky! Break the grid into smaller sections and focus on one part at a time. The 67 looks different from the 97s, so pay attention to the subtle difference in the shapes of the numbers. Keep an eye out for the two loops in the “6” versus the loops in the “9.”
