Reward Policy

1. Reward Calculation Formulas

Rewards are computed when a quiz is submitted. The taker reward is calculated per attempt and the author reward per question; every amount is rounded to six decimal places and recorded in the user ledger.

1-1. Variables

• p — the global correct-answer probability for a question (cumulative correct attempts ÷ cumulative attempts, including the current one). 0 ≤ p ≤ 1. Used for the author reward only.
• Grade — the achievement grade (1–9) for a single attempt, derived from the distribution of scores submitted for that quiz. Below the minimum sample size, an absolute grade based on your score ratio is used instead.

1-2. Taker XP (per attempt)

The taker reward is not computed per question. It is paid once, for the achievement grade of the attempt. The amount for each grade is listed with its current values on the points formula guide; grade 1 gives the most, grade 6 gives 0 XP, and grades 7–9 subtract XP.

• Only your first valid attempt at a quiz is eligible; a retake settles no XP.
• Taking a quiz you created settles no XP.
• Signed-out attempts are graded and recorded but never paid.
• Attempts held or denied by abuse review neither gain nor lose XP.

The XP table and the minimum sample size may be adjusted operationally. Changes are announced in an in-app notice at least 7 days before they take effect.

1-3. Author XP (per question, paid to the quiz author)

• If p ≥ 0.90 (question is "too easy"): 0 XP.
• Otherwise:

1-4. Self-Attempt Rule

When a quiz author takes their own quiz, neither the taker nor the author earns XP for that attempt.

1-5. Referral Milestones

When a user signs up via your referral code and accumulates the following lifetime correct-answer counts, you receive a bonus immediately:

• 50 correct → +200 XP
• 500 correct → +200 XP
• 5,000 correct → +200 XP

Referral sign-up bonus: signing up with a valid referral code increases the taker achievement rewards and author rewards you earn during your first 30 days by 30%. It applies automatically on quiz submission and ends 30 days after sign-up.

1-6. When rewards settle

Some rewards (notably referral milestones) are recorded as pending first and converted to confirmed balance only after additional validation (e.g. anti-abuse review).

QuizNeko reserves the right to update these formulas. Material changes are announced via in-app notification at least 7 days before they take effect.

1-7. Reward adjustment when an appeal corrects a question

When a test-taker's appeal is accepted by AI review, the question's correct answer is corrected and the scores and rewards of all attempts are recalculated. In addition, separately from the AI review fee, 15 XP per question are deducted from the author and paid to the appellant.

2. XP and levels

What quizzes pay is XP. XP is settled once per attempt based on its achievement grade, and low grades subtract it. The XP currently awarded per grade is shown in the scoring guide.

• Only the first valid attempt at a quiz settles; retakes neither gain nor lose XP.
• Attempting your own quiz does not settle.
• Logged-out attempts are graded and recorded but never settle.
• Attempts held or denied by abuse review neither gain nor lose XP.

Floor: your XP never falls below 0. If a penalty is larger than your balance, only the balance is taken.

Levels: everyone starts at level 1. Reaching level 2 takes 100 XP, and each level after that costs 20 XP more than the last (100 · 120 · 140 …). If your XP falls below the requirement for your current level, your level goes down too.

XP boosters are timed passes bought with points. They multiply gains only — never penalties — and do not stack: if you hold several, the highest multiplier applies.

2-1. XP policy

• XP is not cash and has no monetary value.
• XP cannot be exchanged, withdrawn, transferred, sold or gifted.
• XP does not convert into points.
• XP measures quiz achievement, and low grades can reduce it.

3. Point policy

Points are an in-service currency obtained only by purchase. Taking quizzes and other activity do not earn points.

• What they buy: AI explanations, AI quiz generation, single-question regeneration, XP boosters, advanced statistics and author analytics passes, sponsor placement bids, and other digital features inside the service.
• Points are not cash and have no monetary value.
• Points cannot be exchanged, withdrawn or cashed out.
• Points cannot be transferred, sold or gifted to another user.
• Points can be spent inside QuizNeko only.

Previously earned points: points earned from quiz activity before the XP system were converted 1:1 into XP on 18 August 2026. Purchased points and promotional points granted by an administrator were not converted and remain points.
