Deep Submarine
Read Deep Submarine as a board on Phosphor Bay, not as a cash machine. This board waits for an account. A level rung does not open or close it. Closing the frame returns you to the page you opened it from.
The frame opens over this page. The close control sits above the frame, not inside the board. Virtual credits reset with the board's own meter. They are not a balance Sabrinasaidz AS can pay out.
Index 7 on Phosphor Bay is behind the account gate. After sign-in the lock comes off. Rung 2 at 90 XP, rung 4 at 370 XP and rung 6 at 850 XP do not change that gate.
