Reactordle
Name the nuclear power station from country, capacity band, grid date and status
Reactordle asks you to name a nuclear power station in six tries. The four columns are country, a capacity band, the decade the plant first fed the grid, and whether it is running, shut down or still being built.
How the columns behave
Capacity is compared as a band rather than an exact figure, and the arrow tells you whether the answer's band sits higher or lower than your guess. Where the source record carries no capacity at all the cell reads unknown, and an unknown never scores as a match for either side.
Grid connection is the decade a plant first delivered power to the grid, taken from a dated statement on the record rather than inferred. Status is derived from the same record and reads operational, shutdown, under construction, or unknown where the source will not support a call. A substantial part of the pool is already shut down, and the grid-connection decades cluster heavily in the 1970s and 1980s, which is the shape of the industry rather than an artefact of the data.
What this game will not ask you
Accidents are not a puzzle mechanic here. Chernobyl, Fukushima Daiichi and Three Mile Island are all in the pool, as plants, and can be guesses or answers like any other, but nothing in the game scores or quizzes you on what happened at them.
That is enforced rather than promised. The build step refuses to freeze a dataset whose columns are framed around incidents, accidents, disasters, casualties, meltdowns or radiation, so no such column can reach the grid. Those events appear only as context inside the reveal text quoted from Wikipedia, which is the appropriate register for them and the only place they belong.
The data behind it
The 296 stations, with their countries, capacities, grid-connection dates, operators and operating status, come from Wikidata under CC0 1.0, retrieved once and frozen into the game. Nothing is fetched while you play and nothing about the answer reaches your browser before the round ends.
The calendar is 296 days long and uses each station exactly once, ramping within each week from the plants the wider world writes about towards the ones it does not. Where a value is genuinely missing the cell says unknown and scores against both sides, which is preferable to a confident fabrication.
What you take away
The reveal gives you the plant's verbatim English Wikipedia extract under CC BY-SA 4.0, a link to the article, and sourced facts such as the year of first grid connection and the operating company. Up to four bonus rounds follow, comparing other plants in the set rather than the day's answer.
What accumulates is a working map of civil nuclear power. You learn which countries built at scale and when they stopped, how big a large station actually is next to a small one, and how much of the fleet has already shut down.
Questions
Does the game quiz me about nuclear accidents?
No. Accidents are never an attribute, a column or a bonus question, and the build step rejects any dataset framed that way. Chernobyl, Fukushima Daiichi and Three Mile Island appear as plants, and their histories appear only as context in the reveal text.
Is it the same puzzle for everyone?
Yes. Every player gets the same station on the same day, rolling over at midnight UTC, from a calendar fixed before release.
Do I need an account?
No. There is no sign-up and no server-side profile; your streak lives in your browser's local storage and stays there.
