Game modes
Algebro has six game modes. Each picks questions differently and affects your progress in its own way.
Overview
| Mode | Questions | Time | Elo rating | Account | Description |
|---|---|---|---|---|---|
| Quick play | 10 | No limit | Yes | Yes | Fast ranked series without a clock |
| Training | ~10–12 | No limit | No | Optional | Adaptive training, pick a domain |
| Exam | 10–20 | No limit | No | Optional | Test-like — no hints |
| Ranked | 15 | 150 s | Yes (strict) | Yes | Main timed ranked mode |
| Daily challenge | 20 | 180 s | No | Yes | One attempt per day, shared set |
| Duel | 5–20 | Live | No | Yes | 1v1 with a friend, synchronous |
Menu: Play (quick, training, exam) · Train · Ranked · Daily challenge · Duels
Quick play (Quick Ranked)
- 10 questions, no time limit on the series
- Affects your Elo rating (like ranked, but lighter anti-cheat)
- Questions based on your rating and selected adaptive domains
- Spread across 3 domains per series
When to play: When you want rating gains without clock pressure.
Training
- Adaptive — difficulty matches your level per domain
- Non-ranked — does not change Elo
- Pick a specific domain or click Auto — pick for me
- You still earn XP and raise domain levels
When to play: For relaxed practice and learning new domains.
Exam
- Set difficulty (grades 4–6, 7–8, high school, exam level)
- Choose domains and question count (10–20)
- No hints — like a real test
- Non-ranked, but awards XP
When to play: When you want test-like conditions.
Ranked
- 15 questions in 150 seconds (2.5 minutes)
- Elo rating — main mode for leagues and leaderboards
- 5 domains per series
- Strict anti-cheat — your result may be rejected if:
- the game tab lost focus (switched to another tab),
- the series finished unrealistically fast,
- answers were too fast or had repetitive timings.
When to play: When you want to compete seriously and climb leagues.
Daily challenge
- 20 questions, 180 seconds (3 minutes)
- One attempt per day — everyone gets the same question set (fair daily board)
- Levels are derived deterministically from the date — every domain, levels 3–8
- Does not change Elo, but awards XP and a place on the daily leaderboard
- Anti-cheat similar to ranked (focus, too-fast answers)
When to play: Daily, to compare yourself with the community on equal terms.
Duel
- 1v1 with a friend — live, question by question
- 5, 10, 15 or 20 questions — both players get the same set
- You choose difficulty and domains
- Challenge expires after your chosen window (1 h – 30 days) if the opponent does not accept
- Share a link or invite a friend from your list
- Non-ranked (Elo), but awards XP
When to play: When you want a direct head-to-head match.
Math domains (skills)
In adaptive modes you practice selected domains:
| Group | Domains |
|---|---|
| Core (MVP) | addition, subtraction, multiplication, division, mixed, powers, roots |
| Advanced | fractions, linear equations, quadratic, logarithms, trigonometry, word problems |
In profile settings you can choose which domains are in your adaptive pool (default: core set).
After each series
When you finish a series (training, quick play, ranked, etc.), you see a summary with accuracy, XP and timing. The full answer review — every problem with your answer and filters — is collapsed by default. Tap Show answer review to expand it when you want to analyse mistakes.
