Quick questions: pick a zone and answer. Each turn takes 15–30 seconds.
Contest problems: both players solve the same problem. Every passed test is a strike, the first full solution is the finishing blow. Code runs on the contest system's real judge.
Quiz questions and short problems in turn — the fullest test of knowledge.
Damage is the same everywhere. Head — hard question but a high crit chance; legs — easy question, no crit. You guard two zones at the same time.
A question of the zone's difficulty appears. Time is short — no time to search, only knowledge helps.
A correct answer lands the strike; fast and correct is a critical hit. The defender answers too, to hold the block.
When you first enter the arena, you choose your hero: a boy or a girl. Levels, artifacts and power are the same for both — only the look differs.
Every player has their own character. Correct answers earn experience (XP), and XP raises your level. Characters grow from level 1 to 100; higher levels unlock titles, frames and new arenas, while artifacts are won by beating tower bosses.
In battle every 1 HP you take from your rival is 1 XP (the harder the hit, the more XP), and a win adds +40 XP. Correct answers in practice, passed tests and solved problems earn XP too. When the XP bar fills up you level up and get a reward. Each next level needs more XP than the last.
Press the buttons — see how XP adds up and levels rise.
Fast answer: +50% XP
Total to level 100: 575 850 XP
Block — the share of a blocked strike that is absorbed. Strike power raises zone damage.
| Lvl | Health (HP) | Strike | Block |
|---|---|---|---|
| 1 | 100 | 30 | 60.0% |
| 10 | 145 | 39 | 62.7% |
| 25 | 220 | 54 | 67.2% |
| 50 | 345 | 79 | 74.7% |
| 75 | 470 | 104 | 82.2% |
| 100 | 595 | 129 | 89.7% |
A rival of a nearby level is searched for first: for level 1 that is levels 1–2. If none turns up within 10 seconds, the fight starts with a player of any level. CP Duel has no level limit.
| Level | Allowed gap | Example |
|---|---|---|
| Lvl 1–9 | ±1 | Lvl 1 → Lvl 1–2 |
| Lvl 10–29 | ±2 | Lvl 10 → Lvl 9–12 |
| Lvl 30–59 | ±3 | Lvl 30 → Lvl 28–33 |
| Lvl 60–100 | ±5 | Lvl 60 → Lvl 57–65 |
Your character can wear 8 kinds of artifacts. Earn them with knowledge or buy them in the arena shop for coins — and coins on the site are given only for learning. Legendary artifacts are the most expensive.
The arena starts with computer science. Every other subject will get its own arena.
A wrong answer is a wound. To heal it, study the question with its solution and solve it again a few days later.
Each floor is one topic with a boss at the top. Play without a rival; teachers build bosses from their own lessons.
A separate rating for every subject. Rivals and questions match your level — every duel is fair.
Every question is shown with its answer and solution. Even the loser walks away knowing more.
