Star Clusters Megapays Slot RTP, Details & Wager Limits

Reels/Paylines: 4-8 reels + Cluster Pays

Stakes Range: 20p to £20 per spin

Max Win: Jackpots/27,050 x stake

RTP: 96.27%

The Star Clusters Megapays slot is played on a 4×4 grid and uses Big Time Gaming’s Megaclusters engine. Using a Cluster Pays payout system, you need to land 5 or more matching symbols of any size, horizontally or vertically adjacent to land a winning combination. The bigger the cluster, the larger the payout.

Playable from 20p to £20 per spin, there’s a Stake box to the side of the grid. Click on the arrows to adjust to your needs easily. For players outside the UK, you have the option of an Auto function which allows up to 100 autospins along with loss and single win limits.

The Star Clusters Megapays RTP is 96.27%. Whilst this may appear above the 96% slots average, 9.6% of that return rate is reserved for the 4 progressive jackpots. This means that actual RTP rate is 86.67% which is about average for a jackpot game. The non-jackpot version, Star Clusters Megaclusters, has an RTP of 96.54% by the way.

Very high volatility, the maximum exposure is 27,050 x your total stake per free spin. The max win offered in Star Clusters Megaclusters is 23,960 x stake so it’s higher in the jackpot version. In the base game, the most you can win is 1,340 x your total bet with the original version offering 14,407 x stake.

Theme – wish upon a cluster

Theme: Gemstones

High Value Symbol: Purple, Red, Blue + Green Gemstones

Compatibility: Mobile, Tablet, Desktop


With a gemstone/space theme, the Star Clusters Megapays slot is virtually identical to the non-jackpot version, Star Clusters Megaclusters. Using the same graphics and animations, it begins with a yellow backdrop.

You’ll hear a synthesized style soundtrack which gives the impression of a retro, space journey. The lead synth in Europe’s The Final Countdown song is possibly to most popular of all time. Coincidentally, Big Time Gaming have an official The Final Countdown slot.

On the grid, symbols include turquoise, yellow, orange, green, blue, red and purple gemstones. The purple, red, blue and green gemstones are the best paying symbols with 25 or more in a cluster paying 50 x your total stake.

The star wild symbol is the wild and substitutes for all symbols except the Gold Wild. There is no traditional scatter or bonus symbol as such. Here’s a table showing payouts for each symbol:

Star Clusters Megapays Mobile


Big Time Gaming uses HTML5 technology to create all their slot games. Star Clusters Megapays is no different meaning it can be played on mobile, tablet, laptop and/or PC devices. The grid-like setup works perfectly on mobiles but I would recommend playing on a larger screen, especially for the Free Spins feature where the grid expands in size.

Star Clusters Megapays Bonus Features

The Star Clusters Megapays slot, like the original, is based on the Megaclusters engine. There are a total of 4 bonus features. With reactions for consecutive wins, there’s a Gold Wild which has an increasing multiplier. There’s also free spins which is played on a larger grid with up to 256 symbols possible. There are also multipliers. Finally, you have 4 progressive jackpots up for grabs.

Reactions feature

A common staple with Big Time Gaming slot games, a winning combination will lead to the Reactions feature being triggered. The difference is that the winning symbol splits into 4 smaller symbols. This gives you another opportunity to get another win.

When smaller symbols appear, symbols of the same size above them collapse downwards allowing for new symbols to drop in from above to fill the empty positions. Reactions continue until no more new winning combinations are formed.

Gold Wild Multiplier feature


Look out for the Gold Wild Multiplier symbol, a multi-coloured star, that comes with a 1x multiplier. 1 or more Gold Wilds being part of a win will activate the Gold Wild Multiplier feature. The multiplier increases by 1 and increases as long as a Gold Wild is part of the win.

With up to 2 appearing on any base game spin, the Gold Wild Multiplier resets back 1x at the end of each base game spin or if the Free Spins feature is triggered.

Free Spins feature feature


The main attraction is the Free Spins feature which is played when 5 or more reactions occur in the base game. You’ll be rewarded with 2 free spins plus 1 extra free spin for each reaction beyond the fifth. For example, landing 10 consecutive reactions will lead to 7 free spins.

Any Gold Wild Multiplier in play when you trigger the free spins will be carried over too. When the Gold Wild Multiplier reaches a multiple of 10, 2 more free spins are won.

8×8 grid = 64 symbols. 64 x 4 = 256 symbols

More importantly, the grid expands to be 8×8 in size (double that of the base game). When you get a reaction, symbols will split giving you up to 256 symbols on the grid. The 8×8 grid will see 64 symbols in play. If they all split into 4 smaller sizes, that’s 256 symbols (64 x 4).

Megapays feature


Finally, you have the Megapays feature which is activated randomly on any spin. Set in Las Vegas and what looks like the Bellagio, 1 of the lower value royal symbols is chosen to be the Megapays symbol.

With a special respin then taking place, 1 or more instances of the chosen Megapays symbol will lock in position with another respin awarded. Each Megapays symbol landing will move you up to Megapays Ladder.

The higher up the ladder, the bigger the progressive jackpot you’ll win. There are 4 Megapays jackpots with the Mega Jackpot paying out at least €300,000. The real-time jackpot is currently £834,076.89.

To win the Megapays jackpots, you will need at least 4 instances of the Megapays symbol to win a jackpot. 15 or more instances will win you the big Mega Jackpot. Here are all the details:

Number of Instances Jackpot Seed Amount
4-7 Mini €100
8-11 Midi €1,500
12-14 Major €20,000
15+ Mega €300,000

RTP (96.27%)

Max Win (Jackpots/27,050 x)


The original Star Cluster Megaclusters game is 1 of Big Time Gaming’s most popular titles. The Star Cluster Megapays slot will appeal to fans of the original and also to jackpot hunters. On first glance, it may seem BTG have just bolted on 4 progressive jackpots but there are subtle changes.

The visuals and gameplay is identical but the win potential differs. In the base game, you can win up to 1,340 x stake whilst it’s 14,407 x bet in the original game. In the Free Spins feature, the Megapays version pays up to 27,050 x stake as opposed to 23,960 x stake in the non-jackpot game.

You also have the added extra of the 4 progressive jackpots with the Mega Jackpot paying at least €300,000. The RTP is lower in the Megapays version obviously but the potential payout makes up for this in my opinion.

Big Time Gaming has basically released a jackpot version of the popular Star Clusters Megaclusters. They did the same with Bonanza Megapays and Who Wants to be a Millionaire Megapays with more expected in the future.
