The pages dedicated to individual tournaments contain all the necessary information: the tournament schedule, the list of participants, stage results, game scores, and files containing their notations. They're easy to understand, but here are a few clarifications, just in case.
The results of round-robin tournaments (group stages) are recorded in tables.

The columns with indicators are designated by the following abbreviations: И (G) — number of games, В (W) — number of wins, Н (D) — number of draws, П (L) — number of losses, О (P) — number of points.
The table may also contain information about all games played.

In this case, the tournament was a double round-robin: each player played each other twice—blue and red. Players are assigned serial numbers, which are duplicated in the top row of the table. Their games are listed horizontally (from the number and last name to the right) in blue, and vertically (from the same number down) in red. The game result is recorded as two digits: 1:0—blue wins, 0:1—red wins, 1:1—draw, 0:0—mutual technical defeat. Underlined and clickable numbers indicate that the game was actually played, and a file with its notation can be downloaded (more on this below). Ununderlined numbers indicate technical results (one or both opponents fail to show).
To determine who played in a particular game, draw imaginary lines from the cell with its result to the left and up—the numbers will indicate the opponents (the crosses indicate the impossibility of playing against oneself). For example, two games are marked in the illustration: Олег Анохин (Oleg Anokhin) defeated Николай Рыбалкин (Nikolai Rybalkin) in red, and drew with him in blue.
If the tournament was a single round robin, half of the cells will remain empty.

Results of round-robin tournaments with a large number of participants may be recorded in a schedule of games rather than in a scoreboard. In this case, the numbers indicating the outcome are recorded in the same order as the names: 1 for a win for the corresponding player, 0 for a loss (1:1 for a draw, 0:0 for a mutual technical defeat).

Playoff results (Olympic system, knockout games) are recorded using tabbed panels.

Each tab corresponds to one stage, with the stage names appearing on the tab spines. The results of games in a particular series are displayed next to the corresponding pair of names, with the numbers indicating the outcome listed in the same order as the names. If the series rules stipulate replays of tied games, such replays are shown in parentheses.
In a similar manner, but without the tab panel, the results of individual match series are recorded.
The Cup of Nations is particularly noteworthy, as its rules allow for player substitutions during individual series.

In such cases, the name of the starting player does not change, but next to the number indicating the outcome of the game for the corresponding side, the letter "з" ("s") is placed in brackets (the name of the reserve player can be found in the list of tournament participants).
Third-party organizers who publish information about their tournaments on the community forum may design their pages differently, but the general principle of presenting information will be the same.
All actual games played are stored on Google Drive as SGF files. After downloading the file, you can open it with a standard Windows notepad or any other text editor. The notation is a specially encrypted version of the game data, including the move sequence. You can view and analyze the game using the Tensū Arenadesktop client, which reads SGF files from all major venues.

You can view the opened game by sequentially selecting moves using the keyboard arrows or by selecting them randomly from the numbered sequence with your mouse. The client also allows you to create your own gameplay options by clicking on the corresponding points on the board (new options will be saved as branches from the original sequence).
The game analysis, including the additional variations you have created, can be saved by downloading the edited sgf file.
