Welcome to the Starlight Problem Solving 30 day problem solving challenge!

The goal is to solve as many problems as possible in this period, but to qualify for the raffle, you must solve at least 15 different problems and submit at least one insight or hint to each problem from the problems on Starlight Problem Solving in this time period. A hint or insight over all hints/insights of qualifers will be drawn, so posting more hints/hints will increase your winning chance. We may cancel this event if there is not enough participation.

When the challenge ends, a raffle will be drawn where a lucky winner will get a gift card up to $100. The prize will depend on participation and the number of qualifers so please share this with as many people as possible.
