Big X Review

Big X is SYNOT’s latest classic-themed online slot designed to tempt seasoned gamblers. The game provider headquartered in Bratislava, Slovakia, has been quite busy since the beginning of 2023. This game, in particular, comes with classic gambling elements like fruits, bells, big sevens, and diamonds. It's perfect for play on the go, thanks to the flawless HTML5 optimization!

The 3-reel and 3-row grid has 5 paylines, orientated from far-left to right. Lines 4 and 5 are additionally enhanced, and add an x2 multiplier to any win scored on them. The active paytable is displayed on the reels' left side, showing all potential payouts as total bet multipliers.

Several screens are placed beneath the grid and all control tabs, like the Spin button, Autoplay, and Max Bet tab. The title lacks wild symbols substituting for the rest, but the dynamics are good enough for such a type of casino game.

Big X Slot: RTP, Volatility and Key Features

The Big X RTP is widely ranging and can be anywhere from the really bad 85.05% to the awesome 98.01%. This information is per the provider's release memo. We found four versions with RTP rates from 92.20% to 98.01% across the screened casino sites.

The volatility levels remain between low and medium in any case, again according to the developing studio. The average Hit Frequency rate is low - 9.67%, so make sure to use a betting strategy. The range is wide enough - £0.10 to £100 per spin and the maximum win is 500x the total bet!

Diamonds, Red Sevens, and Bells are the highest-paying symbols, awarding 50x, 30x, and 20x the selected bet, respectively.

The Big X online slot lacks free spins, but besides the multiplying lines (4 & 5), it's loaded with a couple of bonus features. Mystery Symbol may appear anywhere on the grid and acts as a scatter. You need 3 in view to activate the feature, and the system will randomly select and award any of the Paytable prizes.

Here is the moment to mention that SYNOT has added a Gamble game in its masterpiece. Every win up to £125,000 can be risked for double or nothing by choosing a colour - Red or Black. If the card face-down is the same, you win. The game can be played up to 10 times in a row!

The Big X feature is the main event in the slot, and it activates whenever the bonus X lands in the middle of the grid. A new set of reels comes into play, and the X locks in its position.

The feature ends when no new Xs appear on the board, and the system selects a prize from the paytable like in the Mystery Symbol feature. Only this time, the highlight reward will be paid per X symbol in view. If all 9 positions are filled out, an additional prize of x50 will be added to the random payout!

Final Lines

In conclusion, the Big X slot has massive potential if you find a high-RTP variant. The frequency of base game payouts might not be the highest, but the prizes are fantastic. Moreover, each of the bonus features is relatively common and pays well. Try the game for free via our demo to build a strategy and go for the jackpot!
