Ranked game (/ranked)
- 15 questions, no time limit
- One Elo ladder (overall rating)
- Question pool grows with your rating — from arithmetic to trigonometry
- New topics unlock automatically (no manual topic picker in settings)
- Task difficulty follows each category’s Elo (e.g. algebra at 1800 → problems at that level), not your training skill level
- Unlock thresholds:
- 400 — arithmetic
- 450 — powers, roots (from easier ones)
- 500 — logarithms
- 550 — fractions, word problems
- 700 — linear equations
- 1000 — quadratics (Δ or full solution), statistics
- 1300 — trigonometry
- 1400 — systems of equations
- 1500 — probability and combinatorics
- 1600 — functions
- 2000 — sequences
- 3500 — number systems (binary, hex)
- 4000 — matrices and vectors
- Questions may use different answer formats: numeric input, ABCD choice, or multiple values (e.g. both roots)
- Statistics with charts — mean and median: numbers above bars are the data points; mode: frequency chart (x-axis = value, bar height = count). Numeric answers are always whole numbers.
- Mini-leaderboard and unlock tier list on the pre-game screen
- Anti-cheat: unrealistically fast or repetitive answer times (tab focus is not penalized)
When to play: When you want to compete on the ladder and climb leagues.
/ranked/advanced redirects to the main ranked game (the former advanced mode was merged into ranked).
Training
One mode with two styles (choose in setup):
Adaptive
- Difficulty matches your level per domain
- ~12 questions, hints after each answer
- Auto — pick for me or choose a specific domain
Fixed level (formerly “exam”)
- Set difficulty (grades 4–6, 7–8, high school, exam level)
- Choose domains and question count (10–20)
- Optionally enable hints after each answer (off by default — test-like)
Both styles: non-ranked, no Elo impact, but XP and domain levels still progress.
When to play: Relaxed practice, learning new domains, or test-like conditions.
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. From Play → Other modes.
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. From Play → Other modes.
Math domains (skills)
In adaptive training 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 ranked play, domains unlock automatically at Elo thresholds (see above).
After each series
When you finish a series you see a summary with accuracy, XP and timing. The full answer review is collapsed by default. Tap Show answer review to expand it when you want to analyse mistakes. In ranked modes each problem also shows its category Elo impact and a short reason (e.g. upset on a hard problem vs a miss on an easier level).
What each mode awards
| Progress | Training | Ranked | Daily | Duel |
|---|---|---|---|---|
| XP | ✓ | ✓ | ✓ | ✓ |
| Domain level | ✓ | ✓ | ✓* | ✓ |
| Elo rating | — | ✓ | — | — |
| Daily board | — | — | ✓ | — |
| Quests | ✓ | ✓ | ✓ | ✓ |
* Daily challenge — only when the result is accepted for the leaderboard (fair play passed).
Session history
Older exam sessions still appear in history (exam filter). Sessions from the former advanced ranked mode display as ranked play. New fixed-level sessions may be stored as training or exam in the database — in the UI you start everything from Training.
