According to tradition, we are going to host the IOI 2025 Prediction Game🔮.
Over the next 5 days, you can submit your predictions for the top 8 contestants in the upcoming competition.
You can make your predictions at: https://qoj.ac/voting_game/vote?competition=ioi2025
The deadline to update your prediction is July 30, 2025 at 10 P.M. (UTC +8). That is, the start of the first contest.
Rules:
You need to predict the 1st to 8th place winners. Each contestant can only be nominated once. If the final rankings result in a tie, any position within the tied range will be considered a correct prediction.
- For each contestant you nominate who finishes in the top 8, you earn 3 points.
- For each contestant you nominate who finishes in the top 16 but not top 8, you earn 2 points.
If you predict the exact rank of a contestant:
- You receive the 3 base points as above.
- Additionally, your first exact prediction earns 10 bonus points, the second earns 20 bonus points, the third earns 30, and so on.
- If you leave a rank blank (i.e., choose not to make a prediction for that rank), you receive 1 point for that empty slot.
If some contestants are tied for places l to r, predicting them as finishing in any position from l to r counts as correct.
Ranking:
Participants in the Prophet Game will be ranked first by their final score, and then by the time of last edit (earlier edits rank higher in case of a tie).
We will post the final leaderboard after the contest is over.
