Millionaire Rush Features

There can be no doubt that Big Time Gaming understands how to keep players entertained. The company knows that special features are the lifeblood of any modern slot, and they’re often the foundation upon which much of its portfolio is built. Millionaire Rush is no exception either. This release is packed full of special features, random bonuses and free spins that bring new opportunities on each spin.


On each spin, large symbols will land upon the 5×5 grid, and when they form part of a winning cluster they will split and react. After doing so, 4 smaller symbols will fill each position to offer even more chances to win – as winning clusters continue to form, up to 100 symbols can fill the play area.


What sets Millionaire Rush apart from previous BTG releases and all other slots is the introduction of the ferociously energetic Megatrail feature. Essentially, it’s a ladder, with 12 rungs, that is randomly determined on every base game spin, and BTG claims there are trillions or permutations – you’ll never see the same ladder twice!

With each winning combination, you’ll climb one rung higher on the ladder, which can trigger 1 of 12 random bonuses.

During the base game, rung 1 of the Megatrail ladder is always blank and rung 2 will always contain one of the following bonuses:

  • Wilds: Up to 10 Wilds are randomly added to the screen.
  • Multiplier Wilds: Wilds with up to 5x multipliers are added.
  • Symbol Explosions: Every instance of the displayed symbol will remove all symbols in its row or column.
  • Symbol Subdivide: Every large instance of the displayed symbol will turn into 4 smaller symbols of the same type.
  • Symbol Upgrade: Every instance of the same symbol will upgrade to the induced symbol.
  • Symbol to Wild: All instances of the displayed symbol will transform into a Wild.
  • Mega Wild: A grid of 4 Wilds is added to the screen – 2 grids of Wilds are added during free spins.
  • Win Multiplier: A multiplier for the entire spin is incremented by up to 10x.
  • Explosions: Up to 3 explosions, in the shape indicated, will remove symbols from the screen.
  • Symbol Duplication: Five big instances of the displayed symbol will be added in a row or column to the screen.
  • 50:50: All of the symbols in the top, bottom, left or right half of the screen will be removed.
  • Max Megaclusters: All big symbols are replaced by 4 smaller symbols.

If you successfully reach rung 12 of the Megatrail ladder, you’ll automatically win a prize of up to 1,000x your stake.

Millionaire Rush Free Spins and Bonus

As there are no Scatter or Bonus symbols in this online slot, all of the action revolves around the Megatrail ladder. When you manage to reach rung 7 during the base game, you’ll trigger 6 free spins on Millionaire Rush.

During the feature, you’ll benefit from an enhanced Megatrail, which is randomly determined once, for the entire free spins bonus. At least 6 random bonuses will be added to the ladder, and rungs 1 and 2 will always contain a bonus.

You can also retrigger the feature by reaching rung 7, which awards an additional 3 free spins, up to a maximum total of 99. Furthermore, reaching rung 12 awards an enhanced bonus prize worth up to 2,000x your stake.

Millionaire Rush Theme and Symbols

Inspired by one of the world’s most popular quiz shows, and following on from the earlier  Megaways release, Millionaire Rush is the latest thematic instalment in BTG’s Who Wants To Be A Millionaire slot series. As soon as you load the game you get the feeling that you’re sitting in the hot seat waiting for great things to happen – it’s truly an immersive and engaging atmosphere backed by the fantastic visuals that Big Time Gaming has become renowned for.

Symbol-wise, you’ll encounter a familiar combination of brightly coloured gems in various shapes and sizes, along with Wilds that can help you create even bigger wins – the larger the cluster you create, the more valuable your payout will be.

Millionaire Rush RTP and Volatility

With a 96.44% RTP, Millionaire Rush comfortably ranks above the industry average in terms of its expected rate of returns. However, as you’d expect from an online slot with such payout potential, it comes with very high volatility. Therefore, the gameplay tends to favour infrequent wins of a greater value as opposed to regular payouts, so you may need to exercise some patience as you go in search of the potentially huge returns on offer.

How To Play Millionaire Rush

Millionaire Rush is a grid-style, cluster pays slot so there are no traditional paylines to speak of. Instead, you simply need to land a minimum of 5 matching symbols in a cluster to land a payout. When you do, the winning cluster(s) will disappear leaving space for new symbols to appear.

Although the multiple features may cause some confusion at first, Millionaire Rush is straightforward in terms of functionality. Like with most BTG releases, you’ll find all of the necessary functions on the right-hand side of the screen. From there, you’ll be able to alter your stake between the £0.20 minimum bet and the £20 maximum bet, brush up on the game’s rules via the collapsible information panel and, of course, spin the reels.

Slotsia’s Review

At first, it may take some time to get used to this slot’s multiple features and mechanics; there’s a lot to take in and it may appear daunting for novice players. However, we genuinely believe it’s worth your time and effort to learn all that Millionaire Rush has to offer.

Big Time Gaming has done an excellent job in creating a new online slot that combines elements from previous titles with the new and exciting Megatrail mechanic that’s sure to deliver engaging gameplay throughout your session. The bonus ladder instils a sense of progression with each winning combination, and the resulting features can generate some fantastic payouts as you go in search of the free spins bonus and the bonus prize at the top of the trail.

Ultimately, Millionaire Rush is one of the most exciting and feature-rich slots we’ve ever come across. Plus, the staggering 55,060x maximum payout showcases the immense potential of the game. So, all in all, we highly recommend that you check out BTG’s latest release – the hot seat and potentially huge prizes await!
