You should be fine tapping into gameplay with the following steps:

Spinning this 5x3-reel slot machine will cost you from €0.10 to €40 per spin. You have a blend of A–9 playing cards and rich-looking orbs to catch a win from any of the 243 paylines. Nevertheless, you will get the support of wild multipliers, mystery boxes, and free spins.

First, this online slot machine packs 243 paylines in its 5x3 reel game grid. While that is a staggering figure for the reel size, the high volatility will give less frequent wins. The big payouts will take a while to land, but we never know what chance holds.

Winning in this slot game requires landing three identical symbols from the leftmost reel. You can take that number to a maximum of five on a payline. Nevertheless, pulling in the high-paying symbols and breaking into the bonus round will most likely take more than a few spins.

When you land wins, you have the standard return to player percentage (RTP) by your side. Also, high volatility does not mean wins will not come, but it will cost you pretty pricey reel spins.

Spinning up Who Wants to be a Millionaire Mystery Box on your mobile device will be a walk in the park. You might have a smaller screen estate, but the gameplay remains solid, even throughout the bonus rounds. If anything, the graphics become crisper because of the higher resolution. Unlike the desktop version, the controls stay at the bottom of the screen. Also, you do not have to download it, as HTML5 technology makes it playable directly in your browser.

Big Time Gaming is the proud developer of "Who Wants to Be a Millionaire Mystery Box." The company boasts innovation despite releasing several slot games in a year. It may have debuted with the new name in 2011, but its experience dates back decades, to 1996.

Gamble Feature

This online slot allows players to double their wins up to five times. You can get this bonus by clicking the “Gamble” button. However, lose it, and you lose your winnings.

Free Spins

Who Wants to Be a Millionaire Mystery Box has up to 20 free spins for any player that lands 5 Scatter symbols. Less than that, and you will get 12 or 7 spins for the bonus game.

The free spins round plays out with 12 multiplier rungs starting at 2x. Each Scatter symbol that appears takes you up a rung and adds one extra spin. The 4th, 8th, and 12th rungs give 3 extra spins with the multipliers. Nevertheless, you can win up to a 50x multiplier for a shot at the max win.

Instead of jumping into the real money game, you can get the demo on this page. That will save your bankroll while you slash through the gameplay for more understanding. You do not have to rush it, as the demo is entirely free.

Who Wants to Be a Millionaire Mystery Box brings in a fiery mix of multipliers, up to 50X. Landing the high-paying symbols will give you decent wins. You can add the wild multipliers, but that will not come close to the maximum win of 12,000 times your stake.

Breaking or landing a shot at that value requires getting to the 12th rung during the free spins round. That means you must continue landing new Scatter symbols to climb the multiplier ladder. Once at the top at 50X, you must land a winning combination with the highest paying symbol.

Building the Who Wants to Be a Millionaire Mystery Box on the original TV show is a brilliant decision. Although it excludes the popular question and answer section, its execution of getting the multipliers is fantastic. Moreover, playing it becomes enjoyable as you only need to Scatter symbols rather than answering questions.

Big Time Gaming continues to innovate, especially after debuting the Megaways engine. Leaving out that game style in this slot seemed unsettling, but the traditional pay structure is a good fit.
