Scramastermoji 1 Mystery Cache

This series is comprised of 19 caches accessible only by boat. Occoquan Creek in this area is usually placid; however after periods of heavy rain there is some noticeable flow at the caches furthest upstream. There are 18 puzzles and one letterbox hybrid. The physical hides are varied, running the range from "paddle up and grab" to "this is crazy". There are plenty of shady spots to take a break along the way. Fall might be a nice time to visit as the banks are tree-lined throughout. Each hint has either "in" or "out" to tell you whether exiting your vessel is required. Hides were done at high water so some might be a stretch. Good luck!

Take two bored geeks playing words with friends and an emoji texting game is born. Can you guess the word that was played using the clues?

You can validate your puzzle solution with certitude.
