+Although you could play on any cab, I've been looking for online cabs in particular.
+The online cabs let you play with an _eAmusement Pass_, which comes with a lot of features I'm going to list below.
+But unless you're a regular at a Round 1, these suckers are hard to find.
+Your best bet is probably to order a card from online if you don't have a Round 1 nearby.
+
+![eAmusement card](./eamuse.png)
+
+Having one of these cards means:
+
+- Saves scores across machines (**BIG**)
+- Saves configuration settings
+- You can unlock songs
+- You don't have to skip the tutorial each time
+- More granular scroll speed changes
+
+You can also sign up for a more premium course for more features, but this has a [more involved registration process][1].
+This gives you:
+

+
+- Ability to see score history (**BIG**)
+- Ability to add rivals and see their scores live in game
+- Darker in-game background
+- Fast/slow indicators in game
+
+The ability to see score history is big, because it means you can track your scores, which in my opinion is a big part of the self-improvement aspect of continuing to play this game.
+
+Also, Konami frequently performs maintenance on their servers, which means online capabilities like score saving will not be available.
+Make sure to have these dates down.
