Who Wants To Be A Millionaire Megaways brings the pressure of the famous television quiz show to Big Time Gaming’s changing-reel format. The blue studio, dramatic soundtrack and familiar Hot Seat all feature, but this time every question could affect the number of Free Spins awarded.
Released in November 2018, it became Big Time Gaming’s first officially branded Megaways slot. The developer retained much of the programme’s identity, including its four-answer questions and three well-known lifelines.
The main game uses six vertical reels alongside an additional horizontal reel. Between two and seven symbols can land on each vertical reel, creating as many as 117,649 ways to win. Since the reel heights are chosen again before every spin, the number of active combinations will regularly change.
It is the Hot Seat feature that makes the game stand out. Triggering Free Spins gives players a choice: accept the spins already awarded or answer questions in an attempt to climb further up a 12-level prize ladder. The three television lifelines are available to help, while safety nets protect part of the accumulated reward after certain points have been reached.
Getting the game started at Heart Bingo only takes a few steps:
Each reel can display a different number of symbols. That means one round may begin with only a few hundred ways to win, while another can open the full 117,649 combinations.
The lower-value symbols are represented by playing-card royals running from 9 through to Ace. Four coloured gemstones make up the more valuable group, with the Purple Diamond sitting at the top of the regular paytable.
Two special symbols also appear:
The Rainbow Wild is found exclusively on the additional horizontal reel. It can take the place of any regular paying symbol but cannot substitute for a Millionaire Scatter.
This symbol uses the familiar Who Wants To Be A Millionaire logo. Three or more Scatters across the six main reels trigger Free Spins and determine where the player begins on the Hot Seat ladder.
The game’s features combine familiar Megaways mechanics with elements taken directly from the television programme.
Every completed win triggers a Reaction. The symbols involved disappear, allowing new ones to fall into the available spaces.
If the replacement symbols create another winning combination, a new Reaction follows without requiring another paid spin. This continues until no further win forms.
Because the reel heights remain in place throughout the sequence, the number of active ways to win does not change until the next paid round begins.
Three or more Millionaire Scatters activate the Hot Seat feature. The number collected determines the player’s starting point on the prize ladder:
Players can usually accept their current reward by selecting Walk Away, or attempt to move one step higher by answering a multiple-choice question.
The full ladder contains:
An incorrect answer can end the gamble and reduce the number of spins awarded. However, the 10-spin and 20-spin levels act as safety nets once reached.
Each Hot Seat question presents four possible answers. As on the television show, three lifelines can provide some assistance:
After choosing an option, the player must press Final Answer. A correct response moves the reward up one level, while selecting Walk Away begins the Free Spins round with the current total.
Free Spins use the same changing reels and Reactions found in the main game, with a progressive multiplier added.
The multiplier begins at 1x and rises by one following every Reaction. It does not return to its starting value between individual Free Spins, allowing it to build throughout the feature.
Additional Scatters can also appear on the horizontal reel during the bonus:
