Game rules

The design of the slot machine will be instantly recognizable to anyone who has watched the TV show, with the reels designed to mimic the famous set. There are A to 9 royal values plus a quartet of gemstones, and winning combinations are created by landing matching symbols on adjacent reels. The best payout comes through the purple diamond, which pays 50 times the stake if a 6-symbol combination hits. The game features symbol cascades, wild substitutions, reactive wins, as well as a bonus game with up to 50 free spins and unlimited win multipliers.

At the start, the slot leads to a second screen displaying a free spins ladder with 8 to 50 free spins on the right and the three lifelines – call a friend, 50:50, and ask the audience – on the left. At the bottom of the virtual slot are four answers – A, B, C, and D – together with a “walk away” and a “final answer” button. The game will then randomly select one of the lifelines and displays which answer has the highest probability to be the correct one.

Players can now choose an answer and lock it in by pressing the “final answer” button. After a little wait to build up the suspense, Who Wants To Be A Millionaire will reveal whether the choice was the correct answer. If it is, then the player advances one level up on the free spins ladder. If not, however, the player has to start over if the wager was between 8 or 10 free spins, and to between 10 and 20 free spins if those safe levels were reached during play. Taking chances at 10 and 20 spins are, therefore, safe since Who Wants To Be A Millionaire will always award the number of free spins in accordance to the safe levels.

There is some strategy involved with playing the Who Wants To Be A Millionaire slot machine. For example, if you see 3 of the “Collect” answers and only one “Advance,” you can use one of your lifelines to continue. If the ratio is reversed, however, you might prefer to save the lifelines for later. When you begin playing, the answers light up, stopping randomly on one of the options.

Extra reel and reactive wins

With every new spin, symbols drop from the top onto the six reels. The top display indicates the total number of active ways to win for that particular spin. The extra reel at the bottom of the game will also spin four symbols into view across reels two to five, which will add an extra symbol position to those reels. Wins are paid for adjacent symbols, reading from left to right, and multiple symbols on one or more reels will multiply the win.

In a winning combination, the symbols become part of a reaction that will see them explode to make room for new symbols to drop into place. This continues as long as a new winning combination lands after a reaction. Wins are added from all results and the player receives the winnings prior to the next spin.

The Hot Seat free spins gamble

A minimum of three scatters in view on any reel after one or multiple reactions in the Who Wants To Be A Millionaire slot will trigger the bonus game on this slot. The maximum number of scatters in a spin is limited to eight. Triggering the bonus game with more than three scatters will start the Hot Seat Free Spins Gamble at one level up for each scatter. On the other hand, four scatters will see the game start at 10, instead of 8 Who Wants To Be A Millionaire free spins.

Progressive jackpot

The Who Wants To Be A Millionaire progressive jackpot, which isn’t available through the Who Wants To Be A Millionaire free play option, is the prize that all players want to win, as it can reach as much as $1 million. The prize is won via the ladder bonus game, and all it takes is a single lucky spin to unlock this incredible real money prize.

Pay table and bonus rounds

You need between 3 and 6 matching symbols on a single payline to win, except the purple diamond, where you need only 2 for the lowest win. The high-paying symbols include all the colorful gemstones and the purple diamond. The green and the blue gemstones feature a maximum payout of 2x the bet, while the red gemstone offers a payout of up to 7.5x the bet. The purple diamond is among the most desired symbols as it comes with a maximum payout of 50x the stake. The card royals from 9 to Ace have a lower value. The Ace and the King pay up to 1.75x the stake for 6 on a win line. The Queen and the Jack have a maximum win potential of 1x the bet, while the 10 and the 9 come with a maximum payout of 9.9x and 0.8x, respectively.

Bonus games

There’s a mini-game within the main game, which you can activate by landing three or more of the scatter symbols showing the words “prize pick.” Do this and you’ll win something straight away. The more scatter symbols you see when the prize is activated, the bigger the prize. The main bonus game is triggered by the other scatter symbol, that of a ladder, which is where players can find the progressive jackpot. If you see three or more of these appear, you can play a bonus round based on the eponymous game show. The catch is that answers are chosen for you at random, so you won’t really benefit from general knowledge if you reach this point. If you get the answers right, you’ll move up the ladder toward better prizes, just like in the game show. The progressive jackpot, the ultimate goal, is at the very top.

Animation, graphics, and soundtrack of Who Wants To Be A Millionaire

Ash Gaming put together the soundtrack for Who Wants To Be A Millionaire and, similar to the Wild West Gold slot, did a great job of creating the show atmosphere by also including music from the show. Another nice touch is the audience clapping whenever you get a winning payout, along with the same music that plays during correct questions. While Who Wants To Be A Millionaire emphasizes the game show atmosphere and music, the slot also offers plenty of animations during payouts.

However, the graphics of the symbols are designed to represent the show, not to impress the player. They don’t look bad, but the symbols aren’t as detailed as the background. The most detailed symbols include the audience choices, check, and question mark. All of the other symbols are acceptable, except for the Millionaire logo and studio wild, which should be updated. The Who Wants To Be A Millionaire free play option includes all of the same bells and whistles as the full version, so you can see exactly what the slot offers.

Mobile availability

Because the slot is in HTML5 format, it can be played on any desktop, mobile or tablet device, regardless of the operating system. This means whether you are on an iOS or Android Device, iMac or Windows PC (or even Linux), you will be able to play the game without any problems. Because HTML5 is cross-compatible with all operating systems, the same high-quality rendering is provided on all devices.

The bottom line on Who Wants To Be A Millionaire

Winning over $1 million was, until now, only found with progressive jackpot slots, but BTG has surprised with Who Wants To Be A Millionaire. The theme of the game show is beautifully executed down to the smallest detail, making this a must-play for Who Wants To Be A Millionaire enthusiasts.

Who Wants To Be A Millionaire slot RTP and volatility

The Who Wants To Be A Millionaire RTP (Return To Player) of the game is set at 96.24%, much the same as the Zeus slot RTP and has stakes from 0.20 to 20 coins possible. Pays for a single six of a kind start at 0.8x and increase to 50x, depending on the bet. The top win potential reaches a massive 50,000x the stake, which is one of the reasons the slot has become so popular. However, like with the Wolf Gold demo, taking Who Wants To Be A Millionaire for a test run will give you a chance to see all of the possible winnings without an investment.
