## Tuva or Bust (Solution)

#### by John Wiesemann with graphics by Mike Yi

For Tuva's relationships, use the historical country of Tuva, which existed from 1921-1944.

### Strategy

Each circle should be filled with a country from the included list. Not all countries on the list will be used. Each box on an arrow should be filled in with the letter of the rule that connects those two countries. Each highlighted arrow spells a word using the boxes it flows through. The arrow indicates the direction of the flow (so the box nearest the arrow is the last letter of the word). The green arrow provides the answer, while the blue arrows form a Feynman quote about Tuva.

There will never be more than one rule that connects two countries that has the same directed-ness, so the box will always be filled in by a unique letter. The relationships between countries can change, use the relationships as the existed during the hunt, January 18, 2013.

### Quote

The sooner you figure out the quote the easier this puzzle becomes. If you google for [Feynman quote tuva] or [Tuva or Bust], the first result is the Tuva or Bust! Wikipedia page. This page includes a quote ascribed to Feynman: "Whatever happened to Tannu Tuva?". If you inspect the length of the words and the directedness of the arrows you'll find this fits into the blue arrowed boxes (without the question mark). This makes the logic puzzle, much easier, but it can also be solved as a logic puzzle.
