Welcome to the the "Fizzy Challenge" Cache
The only requirement to this Cache is that you have found a Cache for EVERY Difficulty & Terrain.
Sounds easy - NOT!
Since each Cache has a unique Difficulty & Terrain Rating (From 1 - 5) there are 81 possibilities.
{sometimes referred to as the “81” grid}
In order to claim this find, you must find Caches of ALL the “Difficulty” & “Terrain” Ratings!
* Does not matter when (or) where the Cache was placed (that you found).
* You just need to complete your Difficulty / Terrain grid to log this as a find.
Since Groundspeak has added the "Statistics" Tab, I can quickly validate if you have achieved this goal!
You can post your 81 grid qualification, but it's not necessary
