Master of Lightning is a 6x5 Nikola Tesla-themed slot by Popiplay with a pay-anywhere mechanic and cascading reels. It features Fireball multipliers up to 100x during free spins, a collection meter that awards 20x for 8 cascades in a single round, and a Chance x2 feature to double bonus trigger odds. It has an RTP of 96% with a maximum win of 10,200x your stake and a Bonus Buy option at 100x.
Master of Lightning is a Nikola Tesla-themed slot game that uses a pay-anywhere mechanic. This means that wins are created by landing at least 8 identical symbols anywhere on the 6x5 reel set. The action takes place in Tesla's dark, gothic-style lab, surrounded by electrified gizmos, lightning-arc effects, and a collection meter.

At MetaWin, Master of Lightning offers a 96% RTP, which is the average for online slot games. It offers high-variance gameplay, which means wins are a bit sporadic. However, those payouts tend to be larger than average.
The base game is pretty straightforward. Set your stake size, hit the spin button, and wait for the results. If you land a win, the cascading reels will cause a chain reaction. First, the win is instantly credited to your balance. Then, all symbols that were used to create the win disappear from the game grid and are replaced by new symbols. If a new win appears after the tumble, the process repeats itself. The round officially ends when no new winning combos appear.
Also, every time you land a cascading win, it is added to the collection box to the left of the reels. If you get lucky enough to earn 8 cascading wins in a single round, you'll win a cash prize equaling 20x your bet. The collection meter resets to zero after each round.

This slot game also features Fireball multipliers, but they only appear during free spins. When they show up, they carry random values ranging between 2x and 100x, and all multipliers are added together and applied to your winnings.
Even though the Master of Lightning slot is easy to play, it has a few features that you need to know about. The game has a Chance x2 feature that increases your chances of triggering a round of Master of Lightning free spins, but it increases your stake size by 25%.

A key feature of the base game is the cascading reels, which Popiplay calls Refill. Whenever a winning combination appears, the symbols used in that combo vanish and are replaced by new ones. If this triggers another win, then the cycle repeats. This chain reaction continues until no new wins appear.
Perhaps the most important feature is the Master of Lightning bonus free spins round. This is where the top 10,200x payout is most likely to drop. Free spins are triggered by landing 4 or more Master of Lightning Tesla scatters. If 4 scatters appear anywhere on the board, you earn 10 free spins. 5 scatters get you 20 free spins, while 6 scatters give you 30 free spins. Landing 3 or more scatters during the free spins activates an extra 5 free spins. There is no limit to the number of additional free spins you can win.
This slot game also features Fireball multipliers, but they only appear during free spins. When they show up, they carry random values ranging between 2x and 100x. All multipliers are then added together and applied to your winnings.
Finally, the Bonus Buy feature allows you to buy your way straight into a free spins round without having to land scatters yourself. While this is pretty convenient, it does cost 100x your bet to activate, which may be a bit too much for smaller bankrolls. Buying your way into a bonus round doesn't guarantee you'll win anything.
Master of Lightning offers an RTP of 96%. This means that if you played millions of rounds, you'd earn an average return of $96 for every $100 wagered. RTP isn't a guarantee. Instead, it's just a long-term average.
This mobile slot is also highly volatile. Whereas low-volatility games typically offer higher hit rates and smaller average payouts, highly volatile games pay out less frequently, but the wins are usually bigger. High volatility games like Master of Lightning are prone to longer dry spells, which is why we suggest establishing a maximum bet size of between 1% and 1.5% of your session bankroll.
High-volatility slots tend to reserve the biggest payouts for the free spins rounds. This is particularly true of the Master of Lightning slot, which only offers those massive Fireball multipliers in the free spins round.
Because Master of Lightning uses a certified RNG to randomly determine the outcome of each spin, there's no way to influence results. However, there are a few things that you can do to give yourself the best chances of playing longer.
Master of Lightning by Popiplay and San Quentin xWays by Nolimit City offer a similar RTP, but that's about all they have in common. Whereas Master of Lightning is a Tesla-themed 6x5 slot game with a pays anywhere mechanic, San Quentin xWays is an edgier prison-themed slot that offers 243 ways to win. San Quentin xWays also boasts a few more features, including Enhancer Cells, Lockdown Spins, Split Wilds, Jumping Wilds, and a Psycho Manhunt.
The biggest difference in these two popular slots lies in the maximum win potential. While Master of Lightning's 10,200x max payout is pretty decent, it pales in comparison to the 150,000x max win potential offered in San Quentin xWays.
