How to choose a slot by type of bonus game

0) Target first, then slot

• Long playtime/WR practice: frequent mini-features, low/medium variance.
• Moderate Risk, Upside Chance: Average Volatility, Multipliers/Retriggers.
• Hunt for a large multiplier (x1000 +): high volatility, rare but fat bonuses.
• Jackpot: Special jackpot rounds/net progressives (high variance).

1) Bonus types: properties and who is right for

1. 1 Freespins (Free Spins)

How it works: a series of free spins with modifiers (multipliers, expanding/sticky Wild, expander symbol, retrievers).

Volatility: medium to high (depends on modifiers).

Who is suitable: those who want a balance between playtime and potential.

Attention points: are there any retriggers, starting factors, fixed/random Wild, choice of mode "many spins/small factors" vs "few spins/large factors."

Bankroll: keep a stock of 100-300 spins of the base game until the trigger (estimate for planning, not a guarantee).

1. 2 Hold & Win/Cash-on-Reels/Re-backs with fixation

How it works: when special balls/coins fall out, a re-spin round is launched; Goals - fill in the field, collect multipliers, mini/midi/mega prizes.

Volatility: low-medium (frequent triggers with moderate payments), there are high options.

Who is suitable: playtime, working out the wager, "even" curve.

Points of attention: the initial number of re-spins, whether the collected multipliers are transferred between the spins, whether there are large fixed prizes and what their frequency is.

Bankroll: 150-400 spin margin before a series of voiced rounds.

1. 3 Pick Bonus ("item selection")

How it works: click on cells/chests, collect symbols/multipliers until the end of the round.

Volatility: more often average.

Who is suitable: for those who do not want an extreme dispersion of freespins, but love controlled bonuses.

Points of attention: are there "traps" (early completion), are guarantees of minimum payments possible.

Bankroll: as for average volatility - a stock of 100-250 spins.

1. 4 Multi-Stage Gumbles/Ladders/Trails

How it works: "go through" several stages to a high multiplier; risk of losing some/all of the bonus is possible.

Volatility: High.

Who is suitable: only if you clearly control the risk and bankroll allows failures.

Points of attention: is it possible to abandon the gamble and take a "guarantee," what is the chance of failure at each step.

Bankroll: stock for long "dry" series, ≤0,5 rate -1% of the daily limit.

1. 5 Progressive/Fixed Jackpots

How it works: bonus wheel/pick/safes with jackpot odds; part of the bet goes to the pool.

Volatility: Very high.

Who is suitable: who consciously plays for the jackpot, is ready for a long distance without large payments.

Points of attention: qualification conditions (minimum rate? side bet?), local/network pool size, "must drop" thresholds.

Bankroll: long distance, minimum qualifying rate.

1. 6 Bonus Buy

How it works: pay 50-200 × rates for instant entry to the bonus (sometimes more expensive).

Volatility: more often high.

Who is suitable: with a sufficient budget for a series of purchases (not 1-2 attempts).

Points of attention: RTP buying mode vs basic, "gumble to start" (risk of losing), bet limits for bonus.

Bankroll: enough for 8-12 purchases at a fixed price, otherwise refuse.

2) Mandatory checks before slot selection

RTP version at your operator. One title can have 96 %/95 %/94% version.

Promo compatibility. Contribution of games to development, exceptions, max bet for bonuses.

Betting steps. Can I hold the rate ≤1% of my daily limit.

Technical quality. Speed, autospin, mobile stability.

Winning ceilings. Is there a cap/cap on bonus/FS.

3) How to match bonus type to your budget (D)

• 'rate ≈ D/300... 600 '.
• Hold & Win: bet '≈ D/400... 700' (frequent mini rounds → more spins).
• Gamble/ladders/high volatility: 'rate ≈ D/800... 1200'.
• Bonus Buy: purchase price 'P ≤ 5-8% of D', N ≥ 8-12 purchases.

4) Bonus slot selection algorithm

Step 1. Purpose → type of bonus.

Playtime/WR → Hold & Win/freespins with frequent retriggers.

Controlled upside → frispins with multipliers/sticky Wild.

Big upside → trails/ladders/high volatility.

Jackpot → specialized jackpot slots.

Step 2. Filters: RTP version, bid steps, promotional conditions (contribution, max bet).

Step 3. Rate setting: ≤1% of the daily limit; for high volatility - closer to 0.5%.

Step 4. Session plan: blocks of 100-200 spins (or 4-6 purchases), a break of 10 minutes, stop loss = daily limit, stop wine = + 50-100% to the deposit (with 50% profit fixed).

Step 5. Check on the spot: whether there are "hidden" restrictions (cap on FS win, reduced RTP in purchase, forced gumble).

5) Fast "matching" goals and bonuses

6) Red flags (bypass)

Reduced RTP is in bonus/purchase mode.

Forced gumble before starting freespins (risk of losing bonus).

Hard cap on winning from FS/bonus, especially under the promo.

Excluding a slot from WR training when bonus is active.

Max bet is below your target rate - it's easy to break the condition by accident.

7) Mini selection checklist (save)

The purpose of the session is formulated (playtime/upside/WR/jackpot).

The bonus type corresponds to the goal.

The RTP version of the slot is confirmed with the operator.

Promotional terms (contribution, max bet, exclusions) are checked.

The rate of ≤1% of the daily limit, the purchase price (if any) fits into D.

Block plan and breaks ready, stop loss/stop wines recorded.

8) Sample session profiles

A. Working out the wager/long playtime

Type: Hold & Win or freespins with frequent mini-features.

Bet: '≈ D/500'.

Purpose: withstand 400-800 spins, fix + 50% to the deposit.

B. Moderate risk with chance of upside

Type: Frispins with Retrigger/Sticky Wild.

Bet: '≈ D/400'.

Rule: Do not gumble the starting bonus mode; fix part of the profit at 2-3 × deposit.

C. High risk / high reward

Type: stairs/trails/mega-mults.

Bet: '≈ D/1000'.

Discipline: blocks of 100-150 spins, early stop at tilt.

D. Bonus Buy-series

Purchase price'P = 5-8% D ', 'N ≥ 8-12'.

RTP purchases ≥ basic, no forced gumbl.

Increases' P '- only from profit and no more than + 10-20%.

Result

Slot selection begins with the goal and type of bonus, and then checks the RTP version, promo compatibility and manageability of the bet. For playtime, take frequent mini-features/re-backs, for moderate upside - freespins with a retrigger/multipliers, for large drifts - trails/stairs (with a small rate and iron discipline), for instant entry - Bonus Buy (only in series). Red flags (lowered RTP, cap, forced gumble, max bet traps) - a reason to change the slot before starting, and not after draining.
