Why this matters
Slot “help” or “info” pages quietly define how the game behaves: whether you can buy the bonus, the maximum you can win, the stake you can risk per spin, and what cool-downs interrupt continuous play. Many of these elements are shaped by regulation, such as the UK’s 2021 slot design changes that banned auto-play, removed “losses disguised as wins,” and enforced a minimum 2.5-second spin cycle.
Bonus Buys: what they are, where they’re allowed, and what changes
Bonus Buys (also called Feature Buys) let you pay a fixed multiple of your stake to jump straight into a feature round. Availability is jurisdiction-dependent. In Great Britain, the regulator pressured operators in 2021 to remove “feature buy-in” elements from sites; the Commission reported that all six contacted operators removed the feature at that time. Practically, Bonus Buys are not offered by UK-licensed casinos.
In other markets, Bonus Buys remain common. Many modern game pages show multiple buy options with different costs and volatility. For example, Nolimit City titles list buy-in prices right on the game page (e.g., Fire in the Hole 2 and Nine to Five). Always read the slot’s info panel to see costs, feature variants, and any separate information the studio provides for buy-ins.
Some studios and reviews note that RTP can differ between base play and a purchased bonus, but this is game-specific and not universal; you must check the game’s own rules/paytable for the active percentages in your jurisdiction.
Caps you must notice: max win, stake limits, and spin speed
Max-win caps are defined by the studio and are usually printed on the game page. Typical language states that if the total win would exceed the cap, the round ends and the capped amount is awarded. Examples include clear statements on Nolimit City game pages. Reading this line prevents unrealistic expectations in “infinite” bonus modes.
Stake caps can also be set by law, not just by a casino. In Great Britain, online slot stake limits went live in 2025: £5 per spin for adults 25+ (effective 9 April 2025) and £2 per spin for 18–24-year-olds (effective 21 May 2025). The UK Gambling Commission’s guidance confirms the dates and that these caps apply to online slots specifically.
Germany’s national framework (GlüStV 2021) enforces a strict virtual-slots regime including a €1 maximum stake per spin and a minimum 5-second interval per spin; operators also implement hourly breaks. Official and expert summaries detail these provisions and the hourly 5-minute pause.
Spin-speed and design rules matter outside Europe, too. Ontario’s standards ban auto-play and set a minimum 2.5-second spin time, with additional UI rules (for example, no “losses disguised as wins”). These are reflected in regulator resources and industry briefings.
Cool-downs and reality checks: built-in brakes on continuous play
Several jurisdictions require tools that interrupt or slow sessions so players can reflect.
In Great Britain, “reality checks” display elapsed session time and must be acknowledged to clear; players can choose the reminder frequency in their account tools. The Commission also offers a “time-out” mechanism that lets you block account access for 24 hours up to six weeks, a licence condition for remote operators.
Germany introduces mandatory breaks: after 60 minutes of online slot play, a 5-minute lockout applies. Licensed sites also show periodic summaries and connect to national systems like OASIS for protection controls. These cool-downs appear in operator help centres and legal summaries tied to GlüStV 2021.
Ontario embeds responsible-design outcomes that reduce intensity (for example, no auto-play) and require clear display of net position, reinforcing natural cool-downs alongside player-set limits.
Reading a slot’s info page: a 60-second checklist
Scan for Bonus Buy availability and price. If the feature is banned in your market, the option will be absent on regulated sites; if present, the info panel should list costs and mechanics.
Find the max-win statement. Studios typically state the cap in “x bet” terms and explain that wins above the cap are truncated at that value.
Check the RTP, volatility, and any per-market configurations. Some regulators require the displayed RTP to match the configured variant on your site; do not assume a generic figure from a review applies to your session.
Confirm stake and speed limits that may apply where you play. Examples include the UK’s 2025 stake caps and Ontario’s 2.5-second minimum spin time.
Locate cool-down tools. In Britain, set a reality-check timer or use time-outs; in Germany, expect hourly breaks enforced by the platform.
What changed recently for UK players
The 2021 UK slot-design tranche banned auto-play, “losses disguised as wins,” and spins faster than 2.5 seconds. In 2025, statutory per-spin stake limits for online slots were implemented nationally, with £5 for adults 25+ and £2 for ages 18–24. These measures combine speed controls with hard monetary caps.

FAQs
Do Bonus Buys increase RTP?
It depends on the game. Some titles publish different RTP for a purchased feature versus base play; others do not. Always read the RTP lines in the game’s info/rules for your market.
Why did my session end early during a huge bonus?
Many slots enforce a max-win cap. When your cumulative win would exceed that value, the round ends and pays the cap. The cap is printed on the game page.
Why can’t I find Bonus Buys on UK sites?
UK-licensed operators removed feature buy-ins after the Gambling Commission’s intervention in 2021; GB regulation disfavors mechanics that intensify play.
What are “reality checks”?
On UK sites, they are on-screen timers that pause play to show elapsed session time and must be acknowledged to continue. You can set how often they appear.
What are the new UK stake caps?
Online slot stakes are capped at £5 per spin for players 25+ and £2 per spin for ages 18–24; both came into force in spring 2025.
