How points are awarded in slot tournaments

A properly designed points formula makes the tournament fair, reduces toxicity and increases retention. Key principles: rate normalization, limitation of the volume of attempts and transparency of rules. Scoring does not change RTP or interfere with RNG - it is an add-on that aggregates spin results into a comparable metric.

1) Goals of the points system

Fairness: The chance of winning does not depend directly on the size of the bet or the length of the grind.

Clarity: the player sees in advance what to do and how the position is improving.

Control of the economy: the projected width of payments and the absence of cannibalization of deposits.

RG by design: The formula is not pushing for higher rates.

2) Basic anti-pay-to-win principles

1. Rate normalization (compare "luck," not "rubles").

2. Cap attempts (the best N spins/period are counted, not the sum of all).

3. Variety of content (fixed bonus for unique providers/games, but with daily limits).

4. Bonus funds are discounted or eliminated.

5. Tie-breaks are deterministic (previously reached - higher; then variety; then seed draw).

3) Scoring models

3. 1. Multiplier Score - Default

Formula:

`Score = round(100 log2(Win / Bet + 1))`

Why it works: the log curve extinguishes the advantage of a large bet; relative luck is more important than volume.

Settings: coefficient 100 - scale for "readable" glasses; can be varied.

3. 2. Rank normalization (Percentile/Rank)

Points = percentile of your best spin among all period spins.

Pros: extreme resistant; Cons: Requires global triage and delays.

3. 3. Best-of-N

Final score = sum/mean/median N best day/event spins.

Recommendation: N = 20/day; for sprints N = 10-15 with a best-of-3-5 median.

3. 4. Median lengths (for sprints)

Every 5 minutes, a mini-score is recorded; total = median of the best three segments.

Effect: Reduces the impact of one "miracle spin."

3. 5. XP hybrid (events + multiplier)

`Score = k1 log2(Win/Bet + 1) + k2 QuestCompletion + k3 VarietyBonus`

Where: 'QuestCompletion' - fixed points for quests; 'VarietyBonus' - for unique providers (cap/day).

4) Rules for bonus funds, jackpots and special cases

Bonus balance:

`Score_bonus = coef_bonus log2(Win/Bet + 1)`, где `0 ≤ coef_bonus ≤ 0. 5`; often '= 0' (complete exception).
Frispins as prize: counted if agreed in advance; recommend a separate factor or exception.
Jackpots: huge extremes → either "cut" the contribution through the log curve (usually enough), or the top cap of points per spin.
Technical repetitions/duplicate events: idempotency counter (UUID) so that one spin is not charged twice.

5) Tiebreakers (hierarchy)

1. Early achievement of the final score.

2. Greater variety (unique providers/games per period).

3. Seed draw: deterministic function from 'user _ id' and event ID (without on-the-fly random).

6) Calculation examples

Example A: single factor

Bet = 2, Win = 40 → 'Win/Bet = 20'

`Score = round(100 log2(20 + 1)) = round(100 log2(21)) ≈ round(100 4. 392) = 439`

Example B: Best 3 out of 10

Points by back: 120, 260, 0, 58, 441, 90, 305, 60, 14, 77

We take the top 3:441 + 305 + 260 = 1006 (or the median of three is 305 if the format is "median").

Example C: bonus funds with coefficient

Win/Bet gives 300 points; source - bonus wallet, 'coef _ bonus = 0. 3 '→ will charge 90.

7) Parameters for different formats

Format	Points base	Cep tries	Aggregation	Comments
Sprint 20-30 min	`log2(Win/Bet+1)`	10–15	median best 3	Fast drive, little grind
Weekly marathon	`log2(Win/Bet+1)`	20/day	sum of best N/day	Diversity bonus
Season 4-8 weeks	hybrid (multiplier + quests)	20/day	amount/weekly average	Statuses/cosmetics at the final
Command	individual account	—	Sum (Top-M deposits/day)	M = 10 - reduces the impact of "whales"

8) Content diversity bonus

Rule: for the first 'M' unique providers/day - by 'B' fixed points.

For example: 'M = 3', 'B = 50'.

Why: Reduce single-slot cycling and stimulate healthy research play.

Limitations: accrued once per provider/day.

9) Anti-fraud and protection against abuse

Event idempotency: UUID, deduplication, retrays.

Micro-rate cycling detecta: cooldown on repeating patterns, one slot/day quotas.

Behavioral biometrics/linkage graph: multi-account search.

Anti-bot: human-challenge in the final minutes of sprints.

Caps: maximum points per spin/day, upper limits of deposits.

Delayed issuance of rare/major awards until KYC (where required).

10) Responsible Gaming (RG) in Formula

Points are counted only within voluntary time/deposit/loss limits.

Formulas do not encourage rate increases (log normalization).

Soft participation caps/day and break reminders.

Neutral copyright (without aggressive FOMO); quick access to self-monitoring tools.

11) UX point display practices

Live feedback: "+ 40 points for x3," "2 out of 20 attempts left."

Transparent rules: briefly on 1 screen + full T&C side by side.

Explanation of the formula: "we count by the factor, the offset of the best N."

Timers: localized deadlines, visible tiebreakers.

A11y: contrast, large numbers, voicing progress, keyboard control.

12) Formula quality metrics

Fairness: variance of points by quintiles, correlation of points with the bet (must be weak).

Playability: average number of attempts scored/player/day,% of players with ≥1 spin scored.

Complaints/10k and the proportion of "abandoned" scenarios.

Monetization: ARPDAU/ARPPU without "overfeeding," LTV-uplift participants vs control.

RG signals: self-regulation, limits, time-on-device.

13) A/B checklist for formulas

Hypotheses: N best (10 vs 20), cap points per spin (on/off), diversity bonus (0/50/100), median vs sum.

Randomization unit: region/channel/cluster to avoid overflows.

Duration: minimum full cycle (week/season).

Guardrails: RTP, complaints/10k, RG metrics - no worse than control.

Report: diff-in-diff by cohort, confidence intervals, power plan before start-up.

14) Out-of-the-box rule templates (can be copied to T&C)

Template 1 - Multiplier + Best N (Week)

Spin points: 'Score = round (100 log2 (Win/Bet + 1))'.

Offset is' N = 20'best spins/day.

Bonus: '+ 50' points for the first 'M = 3' unique providers/day.

Bonus funds: 'coef _ bonus = 0' (not taken into account).

Tie-break: early achievement → greater diversity → seed.

Template 2 - "Sprint 20 minutes"

Cap tries: 'N = 15'. Bottom line = median of the best three 5-minutes.

Jackpot cap: Maximum '700' points per spin.

Bonus funds: 'coef _ bonus = 0. 3`.

Template 3 - "Team top-M"

Individual score - as in Template 1.

Team: 'TeamScore (day) = Sum (Top 10 Score players)'.

Minimum contribution to the score: ≥5 counted attempts/day.

15) Technical Implementation Notes

Event Stream → Scoring → Leaderboard: idempotency, retrai, snapshots for an hour.

Latency up to UI: ≤ 200-300 ms (feeling of "liveliness").

Rule versioning: 'rule _ set _ id', feature-flags per-region, reversible rollback.

Audit: unchangeable logs of rules/charges/issues.

The points system in a slot tournament should be:

1. normalized by rate and volume, 2. limited by attempts (best N), 3. extreme resistant (log curve, medians, mouthguards), 4. transparent in UI and T&C, 5. compatible with RG and anti-fraud.

By following this contour and checking the changes through A/B, you will get tournaments that honestly reward luck and skill, increase engagement and Retention - without breaking the basic math of games.
