Self-revealing hints are available below. I recommend looking at them one at a time, and only in case of frustration. Do not spoil the satisfaction of having the “aha-moment”!
You may prefer to request a personalized hint by email. In that case, please mention which puzzle you are working on, and what you have tried so far. If you’d like only a small nudge, you may try to ask only a few yes/no questions.
