The difficulty/terrain matrix is a chart showing all possible 81 D/T combinations and the number of finds you have of each. A long-standing challenge in the game has been to fill one's matrix by finding at least one cache for every single combination, a feat affectionally called the Fizzy Challenge. Needless to say, this is a tough one for local cachers to achieve, but if anyone does have this lofty goal, we have created this mini-Fizzy Challenge to spur you on!
For those not in the know, challenge caches require the geocacher to meet certain criteria before they are eligible to log the find. "Found it" logs from cachers who do not meet the requirements will be deleted. For full details on the rules about this cache type, you can check out this page.
The posted coordinates will lead you to the entrance of Tunnel B complex in Fort Siloso. The physical cache is hidden somewhere inside the tunnel complex. IMPORTANT: The cache is only available from 10 am to 6 pm.
As for the challenge, to qualify for a Found log you must have found at least one cache for at least 50 D/T combinations (this cache does not count towards your total). You may use the challenge checker below to see if you qualify.
