Illumine Game Recap
How the Clue Works
In fact, each word appeared once and only once on one and only one of the county plaques. Words can therefore be mapped to counties.
The words also appeared in the code book that the teams had just minutes ago used.
arid can/mix(2); less/complete(11) arm less/arid(15) fire led/arid(9); led/both(3); rise/arid(1) mix arid/dry(14) pine runs/role(5); steam/role(13) sold hub/mix(10) steam can/role(7); can/tell(8); fjord/few(4); pine/fjord(12) tell face/role(16) tip face/led(6)
Translating the words into counties yields a collection of triplets. The triplets are ordered according to the number listed along with each entry in the code book.
yakima klickitat grant yakima pacific franklin lewis pacific yakima kittitas cowlitz yakima kittitas cowlitz walla kittitas clallam yakima grant yakima benton lincoln mason spokane lincoln adams spokane okanogan king grant adams klickitat spokane adams klickitat douglas adams chelan ferry adams lincoln chelan douglas wahkiakum spokane thurston wahkiakum cowlitz
Treating the triplets as first-middle-last and plotting their positions in the state, the triplets each form angled connected line segments. Taking the flag as a primer and thinking "flags" leads, in Game speak, to the semaphore flag system. The triplets decode to semaphore letters. Centralia Art Farm sent teams south to the next clue location.
This clue, sadly, was broken because in fact the words given to the teams were not always unique to a plaque. All but two of the teams were skipped.
