The gaming area includes a 3x3 interface with 5 paylines. You’ll also spot the prize table on the grid’s left.

The Plus and Minus modifiers connected to the bet field help you choose your preferred stake per game. Both conservative and high-spending players can stake between €0.10 and €100. The “Max Bet” icon sets the highest possible Big X slot stake. After finding an ideal bet value, click the Play button to trigger one round. The Stop button cancels the current spin instantly.

Meanwhile, the Autoplay mode allows you to gamble automatically up to infinite rounds. The Menu button expands the prize table and game rules controls.

Symbols and Payouts

The Big X slot game has 9 regular symbols derived from the classic slots. Additionally, the paytable includes a mystery icon and a special “X” symbol, both of which activate extra game features. You win when you match 3 of the same icons on valid pay lines from the leftmost column to the right. Winning combinations and payouts are made according to the dynamic paytable.

The Cherries, Lemon, Orange, Plum, and Grapefruits are the low-win symbols that pay between 2x and 5x the bet. Then, the Melons, Bells, Red 7s, and Diamonds award the high-valued wins worth 10x, 20x, 30x, and 50x the total bet, respectively.

Apart from the regular symbols, you can also manage the “Big X” and Mystery icons. Let’s show you what the special icons do in the next section of our Big X slot review.

Big X Bonus Features

As seen from the symbols and payouts section, players should anticipate some pretty basic action. However, the bonuses incorporated into the game should take your experience a notch higher.

Mystery Symbols

Any mystery icons that appear on any reel positions give a random payout value between 2x  to 50x from the paytable.

Multiplying Lines

Any wins occurring on the 4th and 5th lines, as indicated on either side of the reels, will be multiplied by x2.

Big X Free Spins (Re-spins)

Land a Big X icon on the center of the middle reel, and it’ll stick to the reels, triggering a respin. Every new “X” icon that appears holds its position until the feature ends. Otherwise, the respins feature ends, and you receive a random payout from the paytable.

If you’re lucky to have full reels of the “X” icon, you’ll receive an additional 50x multiplier besides the random payout. This Big X free play mode uses a separate reel set.

Gamble Feature

Players can gamble any win not exceeding 125000 EUR. This card-based game needs you to guess the color of the hidden poker card. Guess correctly to boost the win by x2, but you lose if your prediction is wrong.

To limit risk exposure, players can apply the HALVE option and bank half of their payout to their bankroll and risk the remainder. It’s possible to risk in this Big X bonus for a max of 10 rounds, and the Joker substitutes for any shade.

RTP & Volatility

The low to medium volatility makes this gameplay easy, even for newbies. But you should expect a low hit rate of 9.67%. However, the expected Big X RTP is above average at 96.11%. Now that we’ve completed this Big X slot review, we hope you’re familiar with the symbol payouts, playing process, and game bonuses.
