Methods and systems for electric propulsion are provided. An example method includes providing a magnetic shield using an accelerating channel made of a soft magnetic material; generating, by a magnetic system, a radial magnetic field in the accelerating channel to ionize a working substance, wherein the magnetic system includes a central magnetic pole, an outer annular pole, a magnetic circuit, and coils to carry an electrical current; and generating, using an outer hollow cathode and an anode-gas distributor disposed within the accelerating channel, an electrical discharge along the accelerating channel. The accelerating channel provides the magnetic shield to force the radial magnetic field to have a maximum gradient at a location of the central magnetic pole and at a location of the outer annular pole and to force ions of a working substance to pass isolators of magnetic poles, thereby decreasing erosion of the isolators.

A method for executing a slots adventure game comprises the steps of displaying a virtual path for the slots adventure game and presenting to a player a first level (unlocked level) linked to the virtual path and subsequent levels (locked levels) linked to the same virtual path. Further, a selected slots game with the current quest task is initiated based on a player's selection. The player is then enabled to pass game levels by unlocking each of the subsequent levels sequentially.
