Purchase a subscription using Paypal or debit/credit card

All subscriptions have an end date. If you subscribe partway through the year, I'll make sure you get access you the puzzles that you missed through a Google Group. Your subscription will not be renewed automatically, but you will receive an email reminder about renewal near the end of the subscription period.

You're on your honor not to distribute these puzzles to non-subscribers. If you co-solve with a friend or family member, it's fine to buy one subscription for the pair of you. But it's not okay to give a puzzle you've already solved to somebody who hasn't solved it. You can, however, buy a gift subscription for somebody (whether or not you are a subscriber yourself); contact us for more information about that.
