Rules

Format

For every match, each team can earn points. Ranking is based on whoever has the most points:

In 2-team matches, the first place gets 2 points, and 2nd place gets 1 point.

If multiple players have the exact same amount of ISCORE, their points will be split equally. This also means that, if multiple players have the highest ISCORE, the match ends in a tie.

At the end of the World Cup, the teams will be ranked based on has the most points.

Calculating Points

The points are based on the ISCORE calculator (see the "About ISCORE" link in the top right after changing to English via the language icon, fourth from the right).

Score matches are calculated based on the ISCORE formula. Survival matches (except for GFW) are calculated as follows:

(ISCORE No Miss No Bomb Score)*0.5^(deaths)

In survival runs, bombs are counted as 2 deaths.

ISCORE is a scoring metric that compensates for the differences in performance between shot types and categories. The formulas used can be found in the ISCORE rubric with the calculator linked above.

Game-specific Concerns

Touhou 7

A border break is considered a death in survival runs.

Touhou 8

Getting hit during a Last Spell is not considered a death in survival runs. However, ISCORE gives a higher base value in this game to runs that capture all spells (which includes unlocking and capturing every Last Spell) AND do not die/bomb (NN + Full-SC).

Touhou 12

Summoning a UFO is considered a death in survival runs. However, collecting tokens does not affect the score in survival runs.

Touhou 12.8

The survival formula for this game is (gold medals*1.5)-(deaths).

Touhou 13

A manual trance is considered 2 deaths in survival runs. ISCORE gives a higher base value in this game to runs that capture all spells AND does not die/bomb (NN + Full-SC).

Touhou 15

All runs in both survival/score have to be done in Legacy Mode.

Touhou 16

Releasing your season gauge is considered 2 deaths in survival runs.

Touhou 17

Channeling a berserk roar (3 or more of the same animal tokens during roar mode) is considered 2 deaths in survival runs. Breaking your roar (bombing or touching a bullet during roar mode) is considered a death in survival runs.
