Introduction to Gearlab Genius

Gearlab Genius is a casino slot from Bullshark Games, inviting you to the workshop of a clever scientist whose gadgets will help you score big on the grid. In clouds of steam hissing from intricate machinery and the glow of mysterious energy, multipliers attached to each column may suddenly come to life and boost your wins by up to x100, each. During any spin, you may also witness the power of synchronisation, which merges between 2 and 5 reels to reveal matching outcomes when they stop. And once the charming inventor invites you to the secret parts of the lab, you'll get to play out a session of free spins with guaranteed syncs and multipliers.

Get to work and build up your wins until you reach 10,000x the bet, or study some more first in the risk-free demo mode available at the top of the page.

Gearlab Genius places you inside a mysterious steampunk workshop, a place where great inventions come to life. The interior walls are lined with countless shelves carrying loads of books, proving that our scientist is well-prepared for any experiments she's about to conduct. You'll see her next to the grid, wearing a leather outfit held by numerous buckles and holding a meticulous Victorian-style watch. Looks like she's ready to time your efforts on the grid housed by a contraption made of copper pipes, gauges and cogs. If you're ready to start experimenting with the reels, you can launch the game on any modern device, whether you prefer to play on a desktop, a smartphone, or a tablet.

The paytable hierarchy is divided into two sections. To score a win, you must match at least 3 identical icons on adjacent reels, starting from the leftmost one. Among the low-paying symbols, you'll recognise royal playing card ranks, such as 10, J, Q, K, and A, awarding from 0.5x to 0.7x the bet for a combination running through all 5 reels. A wrench, a mechanical glove, a pocket watch, a top hat, and goggles represent the high-paying icons, delivering payouts of between 1x and 3x the bet for a 5-of-a-kind hit. Alongside regular icons, there are also Wilds depicted by the scientist herself and Scatters in the form of a cylindrical device.

Wild Symbols

Wilds substitute for all symbols in the paytable when wins are evaluated. They can also form independent 5-of-a-kind combinations, which pay 5x the bet.

Reel Multiplier

Each of the 5 reels has a field above it. Randomly during a spin, the field may activate and reveal a multiplier of x2, x3, x4, x5, x10, x15, x20, x25, x50, or x100. Any wins passing through that column will be multiplied by the displayed value. If more than one reel with a multiplier contributes to a combination, the values are added together before being applied to the payout.

Synced Reels

During a spin, while the reels are still in motion, between 2 and 5 of them may be selected to become synced. They will be highlighted with a purple glow, and once they stop, they will show matching outcomes.

Super Reel

Any reel may become a Super Reel during a spin. Super Reels are always entirely populated by Wild symbols. If a synced reel is selected, only that one will be affected.

Spark of Genius Bonus

Landing 3 or 4 Scatters anywhere on the grid at the same time triggers 8 or 10 free spins, respectively. During the round, all base game mechanics are maintained, but at least 2 reels are guaranteed to be synced on every spin. Landing any single Scatter awards 1 additional free spin.

Perfect Sync Bonus

With 5 Scatters ending up anywhere in view in a single base game spin, you receive 12 free spins, where all previous mechanics apply, but additionally, at least 2 Reel Multipliers are activated on every spin. Each Scatter landing throughout the bonus awards 1 extra free spin.

Feature Buy

To empower the intricate inventions and reach the most valuable parts of the lab quicker, you may use the Bonus Buy menu with several options for boosted spins and instant bonus triggers.

3x = Bonushunt Featurespins, with a 5-times higher chance to trigger a bonus game.

50x = Quick Fix Featurespins, guaranteeing at least 3 synced reels and 2 Reel Multipliers.

100x = Spark of Genius Bonus with 8 or 10 free spins.

250x = Perfect Sync Bonus with 12 free spins.

Final Thoughts on Gearlab Genius

Gearlab Genius feels like a textbook release from Hacksaw Gaming's growing line-up of partners on the OpenRGS. A recognisable theme wrapped in good-quality graphics, one or two features fueling the base game, which become more frequent, more powerful, or both, during the bonus games. This time around, it's the synced reels and reel multipliers that pour energy into the reels by delivering matching outcomes and boosting wins. And since there's the possibility of synergy between them when both kick in on the same spin, they can drive some satisfying wins your way. With each reel capable of dishing out up to x100, you can theoretically gather an x500 total multiplier. Synced reels can then help you align the symbols in a better way to benefit from the boost, and there's your chance for a serious payday. Naturally, scenarios like that will be few and far between given the random nature of both features, but the potential is undoubtedly there. Plus, the opportunities become much more frequent during free spins, especially the stronger variant, where both mechanics work in unison on every round.

The game's audiovisual angle is well-made, clean, and readable, despite the usual overwhelming amount of machinery that comes with a steampunk theme. Either by chance or deliberately, the creators matched the main character's organised environment with a tidy composition on the reels, making the entire setting consistent and easy to follow. Altogether, it's an exceptionally pleasant scene, empowered by a mysterious yet somewhat motivational soundtrack to match.

Gearlab Genius delivers an elegant synergy of reel syncs and multipliers in a neat steampunk atmosphere.
