Play Genius for Free

The 25 paylines are spread across a standard 5x3 reel set. An elaborate backdrop displays a workshop filled with ancient, mechanical-looking equipment. Our hero is a mad scientist, who looks uncannily like the physicist, Einstein. With his dishevelled hair and no sense of fashion, he has clearly been cooped up in his lab for far too long.

However, his appearance is a welcome sight because, as the game's scatter symbol, he holds the key to the bonus features. Before we get to those, though, we'll take a look at base gameplay and paytable.

Payouts for standard paying symbols are good, ranging from 10x - 1000x your line bet. Wild symbols offer the top fixed prize of 5000x your line bet for the full five of a kind on a payline. They will also substitute paying symbols to increase your win line chances.

The special addition to the free Genius slot's base game is a mystery multiplier feature. For this, you need to land just one of the nuclear symbols anywhere on the reels. Your reward is a 2x or 3x multiplier added to any win line on that particular spin.

There are three fixed bonus features in the Genius video slot and they are all triggered with three of the scientist scatter symbols. Pick a symbol on the reels and it will randomly start one of the bonus options available.

The Potion Bonus starts a picking mini game. On a clinically white table, three brightly coloured potions sit in flasks. You just need to pick one of them for the scientist to squeeze a pipette of liquid and explode the flask. With the mystery of alchemy it'll reveal a prize sum for your bankroll. We've experienced some magical wins during this bonus of up to 70x the total bet.

There's also a free spins bonus which offers a random number of spins. All spins feature a real cash boost in the form of an expanded wild symbol covering the central reel throughout.

The game's final fixed bonus is the Gears Bonus. This side game involves a 3x1 mini slot which feature scatters, multipliers and the word 'lose'. Landing scatters or scatters and multipliers will award good prizes multiplied by your total bet. However, when you land a full payline of those 'lose' words, your bonus will end.

If you're choosing to play for free, or if your online casino doesn't offer the jackpot, then this is where the bonus options end. Fun as they are, the chance of a big jackpot win has a pull most gamblers can't resist. If the chance of one of the three tiered jackpot wins is too tempting, make sure you pick an eligible online casino.

For your best value for money we've rounded up the top sites to play this science-themed slot. Take your pick from here rather than waste time trawling the web. Our selections offer a chance to play for free before you commit to real money.

It's worth noting that, on some of our older tech, we've experienced slow loading when you first access Capecod Gaming slots. As animation and graphics quality increases you'll notice the strain on low processing power. We're only talking a few seconds longer than average. So, if you're not running the latest gaming hardware, you just need a little patience.

Capecod Gaming slots are designed with smartphones in mind.  The Genius video slot is mobile optimised and a fun slot to play when you're out and about. You might want to consider headphones, though. That aggressive soundtrack may make fellow commuters irate.

If you enjoy the mechanics and bonus features for the Genius video slot then Bomber Fruit ticks the same boxes.

It's another Capecod Gaming title, so we have much of the same action, but Bomber Fruit features a more classic theme and simpler aesthetics. A funky, more mellowed-out soundtrack suits the simplicity of this theme, which may be a welcome relief for some.

Novomatic offer a great take on the mad scientist theme in its Reel Attraction slot. 20 paylines here have a bounty of features on the base game with some superb animation. There's also a free spins round and some impressive real cash prize potential.

When you need to let off steam and have a crazy half hour, then the free Genius slot is a great game to lose yourself in. The immersive theme's wacky tone leaves you exhausted, but entertained. There's plenty of chance at making some good real cash wins, too.

The bonus action on offer is fun and rewarding. We'd prefer it if players could choose their mini game, or that each bonus have its own trigger. The random trigger somehow makes you feel cheated of variety. However, it's a small gripe in a fun game which looks good and leaves players feeling buoyant.

For your best value for money be sure to choose an online casino that offers the jackpots. Then you stand a chance of scoring the biggest pots of gold this scientist has on offer.
