Blaseball was made known to us at the beginning of Season β1, however it is uncertain how long it has existed. Some experts speculate blaseball has always existed, half-formed in the corner of our collective vision; while others philosophize that blaseball was synthesized via humanity's darkest hour expressly to absolve us from the sins of mortal hubris by way of instrumentalizing further hubris.

All scholars agree, however, that The Commissioner is doing a great job!

The splort consists of a Season, itself composed of 99 matches across five days ("Monday" to "Friday"). Matches occur every "hour" between two teams, and the team with the higher score is declared the winner, following ancient and arcane rituals involving blalls and blases.

Each team has a total Win-Loss ratio and, at the end of the Season, the four best Teams from each league move on to the postseason, which occurs every "Saturday." This is a best-of-five match series between the 8 Teams. This concludes with the Season's championship Internet Series, when finally one Team is declared the champion.

On "Sunday," known to some as The Slabbath, no splorts shall take place. Instead, the results of the Election are revealed and the events of the next Season are set in motion.

Coins are collected for many reasons, such as greed; however, most participants eventually spend these coins at the Shop to purchase beneficial items to fuel their gambling, or to purchase vote tickets. Coins do roll over from season to season.

Decrees are significant changes to the state of the game or to the rules itself. Decrees are voted on collectively; meaning all participants from all teams will influence and will be affected by the Season's decree.

While it is possible that all decrees are equally doomed, judging by these examples, it is also equally likely that participants tend to vote for the most doomed option.

Blessings are significant changes to individual players on individual teams. Blessings are awarded on a lottery; meaning that the participants voting on a particular blessing on behalf of their team means that their team is more likely, but not guaranteed, to be awarded said blessing.

In recent history, Blaseball has been actively conducted, executed, and played for a number of seasons, beginning with the inaugural season and spiraling into even worse consequences as time inevitably marches on. Experts predict that the splort has "begun its perpetual motion towards a horizon that we may not live to see," and that blaseball will outlive you, the reader, in particular.

One Season is composed of 99 matches per team across five days ("Monday" to "Friday").

The word "season" usually refers to not only the regular season of matches, but also the Internet Series, or postseason championship tournament; plus any other events that occur within Blaseball before the next season formally begins (for example, the immediate aftermath of election results).

A summary of each Season's events can be found on their respective articles.

Starting from Season 20, each Season had both an Overbracket Champion and an Underbracket Champion.
