Millionaire Rush

Big Time Gaming seems most fascinated by the popular television show ‘Who Wants to be a Millionaire?’ The game provider had already released 3 spinoffs of the millionaire TV show before deciding to grace the fans with Millionaire Rush in 2022. The slot has a 5×5 grid layout that can expand up to 10×10, giving it one of the biggest grids as an online slot in the Uk.

While the slot has a Free Spins feature, several exciting payout opportunities are also present in the base game with a random cash prize. Millionaire Rush Megaclusters is another eye-catching game feature which you should look forward to.

Where Can I Play Millionaire Rush Slot?


Big Time Gaming realised the Millionaire Rush Megaclusters slot in the UK on 15th June 2022. The introduction of unique game engines (Megaclusters and Megatrail) and exciting gameplay make this game stand out from its predecessors. Replete with symbol explosions, a win multiplier, and a max win of 55,060x, the stake makes it a top-notch title in BTG’s canon.

Wagering in the game starts from a minimum bet of 0.20 coins, while the maximum bet amount is 20 coins per spin. Although the betting limits are kept towards the lower side, an astounding maximum win in both the base game and free spins round makes it a slot worth playing for. Since the game employs the cluster pays mechanic, wins are formed in clusters instead of dropping on paylines.

As already mentioned, this is not BTG’s first Millionaire-inspired slot. So if you are curious to try more variations on this hit television show, you might enjoy Millionaire, Millionaire Megapays and Millionaire Mystery Box.


If you are already familiar with the popular television show, ‘Who Wants to be a Millionaire?’, it won’t take long to figure out the slot’s theme. The grid is set inside the show’s studio with a Megatrail ladder next to the reels. As the process was in the original show, here, too, each consecutive win takes you higher on the rungs, with the bonus prize sitting at the topmost rung.

Seven gems of different colours are present in the game’s paytable, each offering varying payouts. Except for smaller symbols like teal and yellow gems, all gems pay up to 50x the bet for landing a cluster of 25 or more symbols. However, the purple gem is the highest-paying symbol since it offers relatively higher rewards for winning combinations of less than 25 symbols.

There is also a wild symbol in the game with the potential to substitute all symbols. However, the W wild symbol doesn’t offer any payout or lead to the free spins bonus round.


Having a high variance math model doesn’t come as a surprise for a slot paying the max win of 55,060x the bet amount. High volatility in slots implies wins are usually hard to come by, but when they do, there are good chances of landing big wins. Therefore, while the risks are higher, the slot’s excellent payouts equally match the level of risks.

BTG has implemented an impressive maths model in the Millionaire Rush slot, which becomes most evident from its RTP. The slot’s theoretical Return to Player is 96.44%, which is significantly above the industry average for online slots. This implies that for every 100 coins wagered, expect up to 96.44 coins in return.

However, RTPs are computed by playing slots for a much longer period. So, the data is not applicable if you terminate the session after a few spins. The theoretical value only suggests the average returns players can expect from the game in the long run.

Gameplay and Features

Millionaire rush video slot has two principal gameplay mechanics, Megacluster and Megatrail, rendering the game a solid output. The first one is the Megaclusters mechanic, where a winning cluster of 5 or more matched symbols leads to a win. The higher the number of winning symbols, the bigger the payout.

Reactions Feature

Megclusters is closely entwined with the Reactions feature. Each winning symbol turns into four smaller symbols of random values in this feature. If another win occurs from these smaller symbols, the process continues. At most, you can fit up to 100 symbols into the grid. The Reactions feature will continue until no winning clusters appear on the grid.

Megatrail Feature

Towards the grid’s left side is the Megatrail ladder with 12 rungs with different modifiers. The highest position in this rung always provides a cash prize. At least 3 random rungs have bonus modifiers during the main game. With each consecutive win, you climb a rung. During the 12-rung climb, you might win 12 possible rewards appearing in random positions. They are as follows:

  • Wilds: Up to 10 wilds are added to random positions on the grid
  • Multiplier Wilds: Wilds with multipliers up to 5x might appear on the reels
  • Symbol Explosion: Symbols of one particular type explode and get removed from their row or column
  • Symbol Upgrade: A chosen symbol upgrades to the symbol mentioned in the feature
  • Symbol Subdivide: Big symbols subdivide into four smaller ones
  • Symbol to Wild: A selected symbol type transforms into wild
  • Symbol Duplication: 5 instances of a big symbol get added to the screen
  • Mega Wild: A grid of four wild symbols is added to the screen. 2 grids are added during the free spins mode
  • Win Multiplier: A multiplier of up to 10x becomes applicable for a winning spin
  • Explosions: Up to 3 explosions in diagonal order take place, removing symbols from their path
  • 50:50: Symbols on top, bottom, left or right half of the grid are removed
  • Max Megaclusters: All bigger symbols are replaced by four smaller symbols

Free Spins

Reaching rung 7 during the base game triggers the free spins feature with 6 free spins. Highlighting the seventh rung during the bonus feature provides additional 3 free spins. Up to 99 free spins can be won through this process. Also, at least 6 randomly determined modifiers are added to the Megatrail during the free spins feature.

Millionaire Rush Payouts

Millionaire Rush free spins offer the cash prize of 2000x the bet amount upon reaching the topmost rung. This prize is limited to 1000x the stake during the main game. Apart from this, payouts are extracted by landing winning clusters of 5 or more matched symbols on the grid. During the base game, you can earn up to 33,050x the stake, while the bonus rounds provide the max redeemable prize of 55,060x the bet.


Millionaire Rush might follow a redundant theme, especially from BTG’s perspective, which already listed 3 millionaire-themed games. However, the slot regains its strength in the new mechanic and features department. Megaclusters mechanic joined by Megatrail makes a powerful duo which can offer prizes of a whopping scale. And if you manage to step into free spins mode, things might turn out even better for you.
