Medusa II Jackpots is a 5 reel, 243 ways to win progressive jackpot slot from NextGen Gaming. The non-jackpot version was first released in 2015 and has become a cult favourite – this version just offers a progressive jackpot element as well as locked reels in the base game and free spins. It can be played on all devices from just 50p per spin.

Design wise, Medusa II Jackpots is almost identical to Medusa II – with a mythological theme, the setting is a ruined temple – it has a dark feel to it with Medusa standing out as the main protagonist. Symbols on the reels include A, K, Q, J, 10 and 9 playing cards, gold rings, arrow quivers, statues and snakes.

Medusa is of course the wild symbol – she replaces all symbols except the scatter. She is also the most valuable symbol giving you 10 times your stake for 5 across a payline. Look out for a soldier randomly appearing on the reels in the base game as Medusa is then attacked – Medusa then turns the soldier to stone generating a stacked wild (wild reel). This is known as the Turned to Stone Stacked Wilds feature.

Furthermore, the game comes with a Medusa’s Locked Reels feature – again triggered at random in the base game, any 2, 3, 4 or 5 adjacent reels can lock and spin together displaying the same symbols. This allows for you to form winning combinations much more easily.

Like with the non-progressive jackpot version, it’s all about the Medusa’s Locked Reels Free Games feature – you can access this with 3 or more Medusa II scatter symbols appearing anywhere in view. You will begin with 10 free spins with 3 or more scatters giving you an extra 5 free spins (taking your total to 15).

However, and more importantly, any 2, 3, 4 or 5 adjacent reels lock and spin together on every single free spin meaning guaranteed wins on every free spin.

Now, you can win 1 of 3 progressive jackpots on every spin – you have the Minor, Major or Mega Jackpots which are triggered randomly. This is the only real difference between this version and non-progressive jackpot game. It’s still a good slot though and has potential to pay out up to 2,430 times your stake on every spin/free spin – the locked reels will certainly help you achieve the bigger wins.

Overall, Medusa II Jackpots is just Medusa II with 3 random progressive jackpots – it would have been good to maybe incorporate some new bonus features or different graphics but why change a winning formula? I do recommend though you try the original Medusa slot as this, in my opinion, is still the best version.
