Realistic Nuclear Fusion Reactor

A Roblox experience owned by RBWR Simulation Community.

Description (written by the developer; not a statement by this register)

The game is a first attempt to simulate nuclear fusion realistically. This game doesn't have cooling lasers or blackholes but devices used in real life nuclear fusion facilities although it is simplified enough to create fun and challenging cooperative experience. You also can't blow it up just like in real life so please don't try. The game simulates: - realistic tokamak allowing for deuterium/tritium fusion - tokamak heating by neutral beam and radio waves - separation columns to reuse unburnt fuel - cryostat cooling and magnetic coils - vacuum pumps and cryopumps - helium and molten salt cooling circuits - four turbines with their own components (steam generators, turbine, condenser, auxiliaries) Please be sure to try the tutorial to understand the basics of operations.. The game is not hard but learning it might be challenging especially if you have no experience in our other projects. Be sure to check our other games RBWR/RPWR and our community server.

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.

How many players have ever earned each badge — a proxy for how far players get before they stop. Steep drop-offs mark where a game loses people. Win rate is the past-day share of players who earned it; categories are assigned by a language model from each badge’s own name and description.

2 measurements spanning 10 days. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 85–87 and does not start at zero.

Percentage of votes that are likes, at each of our measurements. A falling line is a game losing its crowd’s goodwill.
