Machines with the most frequent issuance of bonus rounds
What to consider "frequent issuance of bonuses"
Key metrics (record them in the table for each game):
Working benchmark for "frequent bonuses" in mass games:
Why "frequent bonuses" work for popularity
Transparent progress: the player regularly sees the "goal" and its achievement.
Fewer "empty windows": mini-events and quick bonuses reduce DSR.
Session rhythm: motivation failures fall, ASL/SPS (session length and saturation) grow.
Bankroll control: a short cycle to the event → predictable sensations from 100-200 spins.
Mechanics that statistically give a high BER
1. Hold & Win/Re-Spin-banks
Frequent "links": 3-6 characters → short respin with dobors. Typical BER: 1.0-1.6.
2. Collect & Fill
Accumulated N tokens - guaranteed mini bonus/FS. BER depends on the speed of the drop of tokens; really 0.8-1.2.
3. Random modifiers with chance of bonus
Random "blowing" in the base (extensions, additional scatters, "second chance") raises the BER to 0.8-1.1.
4. Light-FS (cheap freespins)
Simple 3 × Scatter triggers with short FS without "heavy" characters - 0.7-1.0.
5. Sticky Respins (Sticky/Lock-on)
Series of mini-bonuses from the base (2-4 backs) - a total of 0.9-1.3.
6. Cluster/Megaways + Frequent Retriggers Feature
Not always "cheap" bonuses, but due to the variability of the field reach 0.7-1.0.
How to select games: a clear checklist
Before inclusion in the selection, run 300-1000 spins (3-5 runs of 100-200):
Thresholds by volatility profiles
Low/medium volatility: BER 0.9-1.4, BAW 10-20x, retriggers 15-25%.
Hybrids (mini-bonus + chance of peak): BER 0.7-1.1, BAW 15-30x, retriggers 10-18%.
High volatility (rare but possible): BER 0.4-0.7, BAW 30-60x; take only if MFR is high and the base is "live."
Fast "red flags"
BER <0.6 without strong MFR - the bonus feels "far away."
STF-median> 160-180 and rare mini-events - rhythm dips.
BAW is very small (<10x) at BER ~ 1.0 - the bonus is "empty," not happy.
Long animations/timeouts - subjectively "cut" the frequency of events.
Mini test method (step by step)
1. We start the table: Spin log (100-200 spins × 3-5 sessions).
2. We fix: the number of bonuses, retrievers, mini-events, long empty episodes.
3. We consider: BER, STF (avg/med), RTR, MFR, BAW and BEV100 = BER × BAW.
4. Conclusion: we take "frequent bonuses" if the BER ≥ 0.8 and (MFR high or STF median ≤ 130).
5. Quality control: duplicate the test on another day/session (at least another 200-300 spins).
Calculation example (simple):
What subspecies usually fall into "frequent bonuses"
Hold & Win/Link- & -Win: fast respins with goodies; short cycles, an understandable goal.
Collect fees: N characters → mini bonus/FS; visual progress increases replayability.
Random Boosters: Random modifiers, "second chances" at scatters.
Light-Free Spins: Simple FS with moderate multipliers and frequent retriggers.
Sticky/Lock-on series: several spins with sticky elements (wilds/mults).
How not to confuse "frequency" with "value"
The frequent bonus with BAW 10-15x without the retryggers may be weaker than the rare bonus with BAW 40-60x.
BER assessment only - error; see BEV100 and RTR, as well as the general rhythm of the base (MFR, DSR).
Buy Feature: not a reference point for frequency - this is a separate economic model. Use only natural triggers to select "frequent."
Recommendations for placement in section
Divide the selection into 3 baskets: Respins/links, Collection/meters, Light FS.
In the card of each slot, show BER, STF median, RTR, MFR, BAW, BEV100.
Explain to the user "what to expect": frequent but moderate bonuses vs less often, but fatter.
Responsibly
The frequency of bonuses does not mean a guarantee of winning. Recommend time/bank limits and remind of responsible play.
Bottom line: slots with really frequent issuance of bonuses are, first of all, respin models, prefabricated mechanics and "light" freespins with support for random modifiers. Select by numbers: BER, STF (median), RTR, MFR, BAW, and BEV100. If the BER ≥ 0.8 with good MFR and visible progression, this is your candidate for the top "Most Popular Slots So Far."
Key metrics (record them in the table for each game):
- BER (Bonus Entry Rate) - the number of bonuses per 100 spins.
- Example: BER = 0.9 means ~ 1 bonus per 110-115 spins.
- STF (Spins to Feature) - average and median number of spins before bonus.
- Watch the median: it is more resistant to "long tails."
- RTR (Re-Trigger Rate) - share of bonuses that are extended/re-triggered.
- MFR (Mini-Feature Rate) - the frequency of mini-events (respins, random modifiers) per 100 spins.
- BAW (Bonus Average Win, x) - average bonus payout in bets.
- BEV100 (Bonus EV per 100) = BER × BAW - the "contribution" of bonuses to the expected return per 100 spins.
- DSR (Dead-Spin Ratio) - the average length of "empty" series without events.
Working benchmark for "frequent bonuses" in mass games:
- BER ≥ 0.8 (that is, ~ 1 bonus every ≤125 spins) is already good.
- BER ≥ 1.0 (≈1 spin ≤100 bonus) - noticeably above average.
- BER 1.2-1.6 (60-85 spin ≈1) - characteristic of respin models/microbonuses.
💡Important: High frequency usually means medium/low bonus payouts (BAW below) to keep the RTP balance.
Why "frequent bonuses" work for popularity
Transparent progress: the player regularly sees the "goal" and its achievement.
Fewer "empty windows": mini-events and quick bonuses reduce DSR.

How to select games: a clear checklist
Before inclusion in the selection, run 300-1000 spins (3-5 runs of 100-200):
- 1. Measure BER and STF (mean/median). Target: BER ≥ 0.8, median STF ≤ 120-130 spins.
- 2. Count MFR. Mini events every 8-25 spins are good; less often than 30 - the risk of lapses in rhythm.
- 3. Rate BAW and BEV100. Example: BER 1.0 × BAW 18x = BEV100 = 18 bets "with bonuses."
- 4. Check RTR. Retriggers ≥ 12-18% stabilize the feeling of the bonus.
- 5. Look at DSR. Long "quiet" sections (40 + empty spins) - minus if there are no compensating mini-events.
- 6. UX/speed. Fast animations, turbo without delay, visual progress counters.
- 7. Stakes. Minimum ≤ 0.1 (in local currency for AU/UK/EU markets) and adequate step.
Thresholds by volatility profiles
Low/medium volatility: BER 0.9-1.4, BAW 10-20x, retriggers 15-25%.
Hybrids (mini-bonus + chance of peak): BER 0.7-1.1, BAW 15-30x, retriggers 10-18%.
High volatility (rare but possible): BER 0.4-0.7, BAW 30-60x; take only if MFR is high and the base is "live."

BER <0.6 without strong MFR - the bonus feels "far away."

2. We fix: the number of bonuses, retrievers, mini-events, long empty episodes.

4. Conclusion: we take "frequent bonuses" if the BER ≥ 0.8 and (MFR high or STF median ≤ 130).
5. Quality control: duplicate the test on another day/session (at least another 200-300 spins).
Calculation example (simple):
- For 500 spins, 6 bonuses were caught → BER = 6/5 = 1.2.
- Average bonus payout BAW = 15x.
- BEV100 = 1.2 × 15 = 18 bets with bonuses for every 100 spins.
- If the target RTP is 96 bets/100 spins, and the bonus part gives 18, then the base should give ~ 78 (plus or minus variance).
