### Tournament - a crazily sophisticated logic puzzle

This is another creation by Naoki Inaba, but as opposed to Island which has a very simple, elegant and intuitive rule, the rules for this one is notoriously sophisticated and it takes a huge amount of time and consideration to devise a not-too-difficult-to-understand format of presentation.

Firstly let's go straight to the source page of the Naoki Inaba site:

The rules translator wrote:
Lines are drawn connecting all the cells. [forming a single connected network]

The complete diagram represents how a tournament occurs.

The three different shapes represent different types of participants.

The Kanji character [translating as "superior"] represents the tournament victory.

Black circles represent a match between two participants.

[The participants and victory symbols have lines in one direction. The black circles have lines in 3 directions. Cells with no symbol have lines in 2 directions.]

The number in a shape is the quantity of matches won by that participant.

The winner of each match continues to a later stage of the tournament. There are no matches which result in draws.

[The winner of each match is determined in a fashion similar to rock-paper-scissors. Square beats Circle. Circle beats Triangle. Triangle beats Square.]

Anyway, here are my own graphical presentations of these puzzles:

My goal is to represent these puzzles in a graphical way such that they can be somewhat understood without any verbose instruction.

Do you think a person with normal intelligence can understand the rules just from the images of the example puzzle and answer, and proceed to solve stage 1?

P.S. Does anyone know a symbol character of a clenched fist from a standard Windows unicode font?

My best find is a "thumbs up" symbol from the "Wingdings" font, to represent the "rock" in "rock-paper-scissors".
