100 Extra Crown Coin Boost
demo and specs

100 Extra Crown Coin Boost is a video slot from Amusnet with a royal theme, dated for 14 October 2026. It plays on a 5x4 grid and is built around a Coin Boost mechanic, with a long list of extras layered on top.

The title and the crown styling point to the classic fruit-and-crowns look that Amusnet is known for, now paired with a coin-collection engine. That makes it a slot for players who like a recognisable royal look but want more happening on screen than a plain line-pays game.

A 5x4 grid, four jackpot coin tiers and eleven named features, with the core numbers still unpublished.

The named features are Coin Boost, Free Spins, Mystery Trigger, Upgrade, Jackpot Coins (Mini, Minor, Major, Grand), Plus Spins, Expanding Wild, Buy Bonus, Gamble and Jackpot Cards. That is a busy set, and it suggests a slot aimed at players who enjoy several routes to a bonus.

On the numbers, the studio specs we hold give the grid, the mechanic, the theme and the feature names. They do not give an RTP, a volatility grade, a max win, a hit rate, a payline count or a stake range. We say so plainly rather than fill the gaps, and this page is updated when Amusnet publishes them.

The RTP for this game is not published, so it cannot be set against the rough 96% UK average. Any figure written here would be a guess, and a guess is no use to someone choosing how long to play. Check the in-game info screen at your casino, as operators can offer different RTP versions of the same slot.

Volatility is also unpublished. What the specs do tell us is the shape of the game: a coin mechanic with four jackpot tiers, from Mini up to Grand. Games built this way usually spread their value unevenly, with many small coin results and a few large ones. How steep that spread is for this slot is something the studio has not stated.

The max win is likewise not published, either as a multiplier of the stake or as a cash cap. That means it cannot be worked at the minimum and maximum stake, because the stake range is not published either. Once Amusnet releases the multiplier and the stake limits, the cash ceiling at both ends is simple multiplication and will be added here.

The same goes for hit rate. No studio figure is on file, and no per-game session log is published on this site, so we do not quote a measured number. The practical point is to treat the first sessions as a way of learning the pace of the game rather than relying on any assumed frequency.

Until the maths is out, the sensible approach is to set a session budget before you start and judge the slot by how the coin and bonus rounds feel on the free demo. If the dry spells between features feel long on play money, they will feel longer on real money.

Here is every feature named in the specs, with a general note on how that kind of mechanic behaves:

• Coin Boost: the core mechanic. Coin-style games centre on coin symbols that carry values and are collected or resolved during a round.
• Free Spins: a bonus round of spins played without a further stake, usually started by a set combination of symbols.
• Mystery Trigger: a feature whose start is not tied to an obvious symbol pattern, so it can arrive without warning.
• Upgrade: a step that improves something already in play, typically symbol or coin values, during a round.
• Jackpot Coins (Mini, Minor, Major, Grand): coins that carry fixed jackpot tiers, ranked from Mini at the bottom to Grand at the top.
• Plus Spins: extra spins added to a round, extending how long a feature runs.
• Expanding Wild: a wild that spreads to cover more of its reel when it lands, helping line wins form.
• Buy Bonus: a paid shortcut into a bonus round instead of waiting for it to trigger.
• Gamble: an optional risk step offered after a win, where the player can put it at stake for a chance to increase it.
• Jackpot Cards: a card-themed route to the jackpot tiers, separate from the Jackpot Coins.

The studio has not published the trigger conditions, the number of free or plus spins, which reels the Expanding Wild covers, how the Upgrade works, how Mystery Trigger is awarded, or the values and odds attached to each jackpot tier. This page is updated when Amusnet publishes them.

Buy Bonus is switched off for GB players at UKGC casinos. UK rules do not allow paying to skip straight into a bonus round, so the option will not appear for you, though it can exist in other markets.

The base game uses a 5x4 grid, five reels by four rows. The number of paylines is not published, so we cannot say how many lines or ways pay. Between features, the play is likely to be a steady run of spins where coins, wilds and mystery triggers are the events to watch for.

The stake range is not published, so we cannot name the minimum or maximum bet. Once it is out, the low end will suit players who want long sessions and time to see the features appear, and the high end will suit those who accept bigger swings for the jackpot tiers.

On bankroll, because the volatility is unstated, the cautious route is to start at the lowest stake available and move up only if the pace suits you. Keep the budget fixed for the session, and treat the Gamble feature as an extra risk on top of the spin, not a way to recover losses.

On mobile, Amusnet builds its slots for phones as standard, so expect the same grid and features on a handset as on desktop. UK rules apply on a phone exactly as on a computer: no Buy Bonus, a visible clock and session reminders, and no autoplay options that break UKGC rules.

Among coin-mechanic slots, this one sits towards the feature-heavy end. Eleven named features, four jackpot tiers and a second route through Jackpot Cards is a lot for one game, and many slots of the same mechanic offer fewer moving parts.

We cannot say whether it is riskier or steadier than its peers, because the volatility is not published. What can be said is that a ladder from Mini to Grand usually means the ceiling is set by the top tier, and the lower tiers give the game its rhythm. A higher ceiling is normally paid for with longer gaps between the bigger results.

Its own ceiling is not published yet, so the trade it offers cannot be sized. The similar-slots table that follows shows real comparison figures for other games of this type, and the gaps in this game's row will fill when Amusnet releases its specs.

It suits these players:

• Players who like a royal, crown-styled look and want a modern coin mechanic behind it.
• Players who enjoy a long feature list and several routes into a bonus rather than a single trigger.
• Players chasing named jackpot tiers, from Mini to Grand, over a plain cash-multiplier ceiling.
• Anyone happy to try the free demo first to learn the pace before committing real money.

Skip it if you need a published RTP, volatility and max win before you play, or if Buy Bonus is a big part of how you like to play, since it is off for GB players. Anyone who prefers a plain, few-feature game may also find this one busier than they want.
