Once entering the Sinnoh underground you can use the buttons to move anywhere around the place. On the top screen of the DS, there will be shining stars seen which gives away a hint that there is a treasure hidden. The player must go to the location where you can tap with your stylus pen once or maybe twice to act like a radar which sees the hidden treasures where you must dig to get them. There are also treasures hidden under the ground but not only that, there are also traps hidden in the underground where you must be careful. Furthermore, there are a lot of sphere's hidden in the underground which the player can trade them for traps or decorations.{{-}}

''Spheres''are the currency of the Underground. Spheres can buy you anything, from traps to treasure and even [[item]]s to decorate your secret base. If you bury spheres in front of you and leave them there after a while they grow larger. If you bury a lot of spheres of the same colour in front of you and then dig it up a larger sphere is obtained. You can also find [[Fossil]]s, which can be restored in [[Oreburgh City]], Heart Scales, which are to give to the [[Move Tutor]] so he can teach your [[Pokémon]] other moves that it has learned by leveling up, and rarely [[Evolution Stones]]. Once in the game, a player may also obtain a random [[Plate]] by digging for spheres. On the floor, traps can be picked up. People can play together using DS wireless Communications in the Sinnoh Underground. They can steal flags from each other's secret bases to upgrade thier own. They can also interactand"chat".

==Activities==

=== Fossil Dig ===
+
[[Image:digg.jpg|thumb|Digging treasures.]]
+
Fossil Dig is a main activity in the Sinnoh Underground. You can find various of valuable items while searching for fossils. Those items cannot be easily found around the Sinnoh Region while you're not in the Sinnoh Underground. After you've tapped on the wall you can dig out various of treasures. You have two tools to dig out items out of the walls. Those two items are: a <span style="color:red;">Hammer</span> and a <span style="color:blue;">pickaxe</span>. Those two items have different level of power which can affect the stability wall to crumble. If you are using the hammer it can let you dig large areas very quickly, but it there is also a catch by using it which it clefts the wall quickly. The pickaxe can let you work at small areas very carefully, but it only increase the cleft in the wall a bit on each time. Each time while you are digging using one of the two items, the cleft meter will let you know how big the cleft actually is. Once the meter is at the left end of the screen, the wall start to collapse.
