Geez, this is a pretty cool and fun concept! (Both the jam and Add to Odd itself!)

Fun little game! I'm having a little trouble understanding the words that appear at the top and exactly what I need to do... my first instinct is that the words are "goals" of what I should try to hit next, but they don't seem to "clear" in any predictable way. Maybe I just need to play some more though.

EDIT: A few more plays and I worked out the goal. It makes sense, just didn't realize at first that the "evens" and "odds" apply to your total score and not the individual numbers. :)

(Also, I think your Chain Letter Jam Link #4 goes to the #3 game)
