Lightweight Version for Small Screens (e.g. 3DS)

On devices with small screens or older browsers, the regular layout can spill sideways off the screen and become hard to use. For those cases, we offer a frame-free, single-page lightweight version.

How to use it
On the screen after "Start Game," enter your ID and password in the "Lightweight version for small screens (3DS, etc.)" section near the top, then press Log in (lightweight version).
