Scoring System

The Jeopardy competition will use dynamic scoring. Each challenge is worth 1000 points at the beginning of the competition, regardless of category or difficulty. A challenge’s value decreases to 100 points as more teams solve the challenge, according to the following formula:

$$\mathsf{score} = \left\lceil \mathsf{maximum\_points} \cdot \left( \frac{\mathsf{minimum\_points}}{\mathsf{maximum\_points}} \right)^{\left(\left(\frac{\mathsf{max}(0, \mathsf{\# solves}-1)}{\mathsf{max}(1, \mathsf{\# teams}-1)}\right)^\alpha\right)} \right\rceil$$

Here,

$$\mathsf{maximum\_points} = 1000\newline\mathsf{minimum\_points} = 100\newline \alpha = 0.705$$

so the final formula is as given by the following Python function:

def score(solves: int, teams: int, minimum_points: int = 100, maximum_points: int = 1000, alpha: float = 0.705):
    decay = (max(0, solves - 1) / max(1, teams - 1)) ** alpha
    return math.ceil(maximum_points * (minimum_points / maximum_points) ** decay)

The total number of points of each team is the sum of the points across all challenges solved by that team at the end of the competition. Specifically, it is not the sum of points the challenge had at the time of the solve. Each team receives exactly the same amount of points for a given challenge.

Example point values with 42 participating teams:

Challenge solve count	Points
0	1000
1	1000
2	846
5	640
10	454
15	340
25	207
35	133
40	109
42	100

“First bloods” (the first solve of a challenge) will be recognized and celebrated, but will not award additional points beyond eternal glory.

7.2. Attack-Defense Scoring

For the Attack-Defense scoring formula, please refer to the Attack-Defense wiki at https://wiki.ad.ecsc2026.de/scoring/

7.3. Aggregated Scoring

The aggregated scoring is computed by combining teams’ scores on the two competition days as described by the following formula. For each team:

aggregated_score = jeopardy_score + ad_normalized_score

where jeopardy_score is the team’s score at the end of the jeopardy competition andad_normalized_score is the team’s score at the end of the attack/defense competition, normalized on the same scale as the jeopardy one as follows:

ad_normalized_score = ad_score * (jeopardy_winner_score / ad_winner_score)

where ad_score is the team’s score at the end of the attack-defense competition and jeopardy_winner_score and ad_winner_score are the scores of the teams who got first place during, respectively, the jeopardy and attack-defense competitions, considering only official teams.

After the score for each team is computed, two separate scoreboards will be created for official and guest teams.
