From Torah Tidbits: "TTRIDDLES are Torah Tidbits-style riddles on Parshat HaShavua (sometimes on the calendar)."
The TTRiddles which appear on this site, have not appeared in Torah Tidbits, and neither I, nor the riddles are associated with the OU, with the Israel Center, or with Torah Tidbits.
Despite this, the riddles qualify as TTRiddles, since they follow the style of the actual Torah Tidbits TTRiddles.
Answers can be submitted by email, to an address you should be able to find by looking at the address of this page. I haven't decided how or when to publish the answers to the TTRiddles.
