Tesla’s Invention: Slot Overview

Say “Tesla” today and most people immediately think of Elon Musk’s electric cars and reusable rockets. Yet Tesla Inc. actually takes its name from Serbian-American inventor Nikola Tesla, credited with, among other breakthroughs, AC (alternating current) power. That legacy is clearly the inspiration behind Relax Gaming’s online slot Tesla’s Invention. Here, the core objective is to gather power-ups that charge up features like multipliers and symbol upgrades, which then come into play during rounds of free win spins.

One of Tesla’s Invention’s strongest points is the soundtrack. Through speakers or headphones, it delivers seriously dramatic music—perfect for imagining a determined scientist racing around a workshop, yanking levers and cranking dials to tame nature’s forces as lightning cracks and rain lashes the windows of a high tower lab. In contrast, the visuals felt a bit underwhelming. They’re fine on the surface, but something seems slightly off, and that oddness runs through much of Tesla’s Invention, making it feel less like the work of Relax Gaming’s usual top-tier artisans.

Using the coins button, players can set stakes from 20 c to $/€100 per spin. Playing at these settings delivers an RTP of 96.41%, while purchasing free spins lifts it to 96.64%. Built on a highly volatile model, Tesla’s Invention runs on a 6-reel, 5-row layout offering 15,625 ways to win.

The low-paying symbols are the elegant cursive J-A card ranks, awarding 0.4 to 0.5 times the bet for a 6 OAK combination. Above them sit 4 electrified pieces of equipment as the high pays, where landing 6 of a kind returns 0.8 to 1.5 times the bet. Finally, when wilds appear, they substitute for any standard paying symbol.

Tesla’s Invention: Slot Features

A key focus in Tesla’s Invention is building up power-ups to strengthen the free win spins round once it’s triggered—power-ups can also be purchased. On top of that, watch for Oscillator Respins.

Electric Dreams Collection Elements

In the base game, 4 elements can be improved. Electric boosts can land on any symbol and charge the 4 collection elements. These power-ups are stored until the free win spins feature begins. After activation, every collected power-up is activated for the entire duration of the round. The available upgrades are:

• Win Spins – increases the number of win spins when the feature triggers.
• Multiplier – increase the multiplier to be applied to each win spin.
• Wilds – the more wilds collected, the more wilds added to the reels for win spins.
• Symbol Upgrade – each upgraded symbol collected swaps a low pay symbol for the corresponding high pay one.

Electric Dreams Win Spins

During the base game, landing scatter symbols on the far-left and far-right reel awards 6 win spins plus any additional win spins that were collected. True to the feature name, every free spin is guaranteed to generate a win. Any collected wilds are placed onto the reels before the round starts, and the saved multiplier is applied to each win spin. When the win spins finish, all collection elements reset to a random state. The win spins feature can be bought for 88 times the bet, launching the round with random state values.

Oscillator Respins

Hitting at least 6 coins anywhere on the reels starts 3 Oscillator Respins. Coin values range from 1x to 10x the bet, while Tesla Power Pot symbols show the Minor, Midi, Major, or Mega prizes paying 10x, 25x, 250x, or 10,000x the bet, respectively. Addition symbols showing +1, +2, +3, +4, or +5 can also appear. When they land, they add their value to every coin currently on screen. Any new symbol landing resets the spin counter back to 3, and the feature stops once spins run out or there’s no space left.

Tesla’s Invention: Slot Verdict

It’s hard to shake the impression that Relax Gaming brought in the B-team for Tesla’s Invention. It doesn’t carry the same gleaming finish or eye-catching visual punch that Relax usually delivers. Add in a paytable dotted with spelling errors, and it starts to feel like the main Relax Gaming stars had the day off when Tesla’s Invention was put together. Sure, not every release can get the same level of investment as something like Money Train 5, but the weaker attention to detail and muted enthusiasm made Tesla’s Invention stand out against Relax Gaming’s broader catalogue of premium titles.

Instead, Tesla’s Invention feels more at home next to slots like Los Cuatro Esqueletos or Deep Descent, leaning more toward “filler” than “flagship.” The best part is the four-part collection system, which can make the free win spins round more charged-up and engaging. Still, as with all win spins, “guaranteed win” doesn’t equal “guaranteed big win”—though with a max payout of 10,000x the bet, a major hit is at least theoretically possible. Oscillator Respins also come across as a bit unnecessary, almost like a bolt-on extra that siphons RTP that could have been better focused into win spins. Then again, hold ’n wins are popular, so why not?

That “eh” vibe follows Tesla’s Invention from beginning to end—not in the sense of “eh, give it a try,” but more like “eh, it’s fine, ship it.” It’s a decent enough machine, just one that doesn’t reach Relax Gaming’s usual high bar.
