Extra Chilli Megaways slot review

Extra Chilli Megaways slot at a glance

Extra Chilli Megaways comes from Big Time Gaming, the Sydney studio that created the Megaways mechanic and is now part of Evolution. It sits firmly in the high-volatility corner of our slot reviews.

The headline numbers are simple. Six reels each show between two and seven symbols, a horizontal reel adds extra symbols across the top, and the number of ways to win changes on every spin up to a maximum of 117,649. The top prize is 20,000 times your stake.

How the features work

Megaways and Reactions

Every spin, each of the six reels picks a random height between two and seven symbols. Multiply the heights together and you get the number of ways for that spin. When all six reels show seven symbols, that is 7 × 7 × 7 × 7 × 7 × 7 = 117,649 ways.

Wins trigger a Reaction: the winning symbols are cleared and new ones drop in to fill the gaps. If the new symbols form another win, the chain carries on, so a single paid spin can produce several wins in a row.

The HOT free spins

The scatter symbols are the letters H, O and T, plus a +4 symbol. Land three or more of them, spelling HOT or using +4 in place of a letter, and you get 8 free spins. Each +4 scatter in the trigger adds 4 more spins on top.

Before the round starts there is an optional gamble wheel. You can keep the spins you have or spin the wheel to try for extra spins, accepting that a gamble can also end with fewer. Whether your casino's version shows the wheel is something to confirm in the game's help screen.

The multiplier that doesn't reset

This is the part that gives the game its reputation. During free spins the win multiplier rises by 1 with every Reaction, and it carries over from one free spin to the next instead of dropping back. A long chain early in the round lifts every later win.

1. A paid spin lands three or more H, O, T or +4 scatters.
2. The game awards 8 free spins, plus 4 for each +4 scatter.
3. You choose whether to use the optional gamble wheel for more spins.
4. Each Reaction during the round adds 1 to the multiplier.
5. The multiplier stays at its new level for the rest of the round, then the total is paid to your balance.

Extra Chilli Megaways RTP in the UK: why it isn't 96.82%

You will often see 96.82% quoted for this slot. That figure includes Feature Drop, a paid option that sends you straight to the free spins. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so the version on UK apps runs without it.

Without Feature Drop the RTP is up to 96.41%, and casinos can choose versions as low as 96.15%. The difference looks small, but it is the casino's choice, not yours, and it changes what each pound costs you over time. The Commission's games warning to online operators (opens in a new tab) explains why feature buy-ins were withdrawn.

Apps don't run lower RTP than websites by default. The version is set by the casino's game supply, which is why we answer whether RTP is lower on casino apps with the same advice: check the help screen of the game you are actually playing.

What a £20 budget looks like on Extra Chilli Megaways

RTP is a long-run average across millions of spins. The house edge is what is left: at 96.41% it is 3.59%, so on average you lose 3.59p for every £1 you stake. At the 96.15% version it is 3.85p.

Those averages hide how this game actually feels. High volatility means most of the return is concentrated in the free spins and long Reaction chains. Twenty spins at £1 can easily come and go with nothing but small wins, which is why a 10p stake gives you far more chances to see the feature for the same £20.

Treat the £20 as the price of the entertainment. Setting a deposit limit before you start is the simplest way to keep it at £20.

The 20,000× max win in pounds

The cap is 20,000 times the stake for a single spin. At 10p that is £2,000, at 50p it is £10,000, at £1 it is £20,000 and at the UK maximum of £5 it is £100,000.

A cap describes the ceiling, not a likely result. The free spins multiplier is what makes large wins possible, and that same design is what makes long dry spells normal. Losses are the likely outcome over time.

Playing Extra Chilli Megaways on a phone

Current online slots are generally built as HTML5 games, so they run inside a casino app or a mobile browser without a separate game download. You open the game from the app's lobby, and it loads like a web page within the app.

With six tall reels plus a horizontal reel, the screen is busy. Whether you can play in portrait or need to turn the phone sideways depends on the version, so try both; our guide to landscape and portrait mode covers the general settings. Long Reaction chains also mean each paid spin takes longer to resolve than on a simple five-reel game.

1. Open your casino app and search the lobby for Extra Chilli Megaways.
2. Open the game's help screen and note the RTP shown.
3. Set your stake with the plus and minus controls before the first spin.
4. Press spin for each round, as autoplay isn't available in Great Britain.
5. Watch the net position and session time shown on screen.

On an iPhone or an Android phone the main practical points are a stable connection and enough battery for a long free spins round.

UK rules that shape Extra Chilli Megaways

British players get a slower, more transparent version of this slot than players elsewhere. These rules come from the Gambling Commission and apply on every licensed app.

The Commission's online slots stake limit guidance (opens in a new tab) sets out the £5 and £2 caps, and our page on slot stake limits explains how they work. The design rules are covered under game design rules, and the wording sits in the Commission's RTS 14 responsible product design standard (opens in a new tab).

Slots like Extra Chilli Megaways

If the endless multiplier is the draw, the closest relative is Bonanza Megaways, the studio's 2016 gold-mine game, whose free spins multiplier also climbs with every Reaction. White Rabbit Megaways and Danger High Voltage are other Big Time Gaming titles with different features.

Extra Chilli Megaways review verdict

It suits players who enjoy a slow build towards a single feature and keep stakes low enough to reach it. If you prefer steady small wins, a medium-volatility game is a better fit.

Where to play Extra Chilli Megaways with a welcome offer

• PlayOJO: a first deposit of at least £10 brings 80 free spins worth 10p each, but they are on Big Bass Bonanza rather than this game. Winnings are paid as cash with no wagering; Northern Ireland is excluded and the offer can't be combined with others.

You have 48 hours to accept them and 7 days to use them, with no wagering on winnings; PayPal, Skrill, Neteller, Paysafe, prepaid and certain debit cards don't qualify.
