The game has 5 reels with up to 25 paylines. For the latter, you can expect a min and max coin size of 0.01 and 2 coins respectively. One thing to note is that players can't change the min/max coin per line which is one. But overall, the range is still flexible enough with the total max you can bet on all paylines being 50 coins.
Medusa video slot actually features three bonus features. They're Turn to Stone Re-spins, Once Bitten bonus, and the Pegasus bonus. With the first one, it's activated by the Wild symbol, otherwise known as Medusa.
Land three Wilds on reel 2, 3, and 4 and she'll turn the reels into stone. From there, one of the reels cracks open to reveal Medusa herself expanding all over the reel to form bigger combos. You'll be given three more free spins as well as a 3x multiplier on your total bet.
For the Once Bitten Bonus, it can be activated by the Scatter symbol. Hit three of those, and you'll be awarded 10 free spins in addition to an x2 multiplier. During those free spins, you can also trigger three Super Spins by landing the Soldier symbol on the third reel. Each of those Super Spins come with an x5 multiplier attached as well. If you hit three more Scatters, you'll re-trigger the free spins.
Lastly, the Pegasus bonus is triggered by landing three Pegasus icons. You'll have to pick between the three icons, with each boasting different cash prizes. But your best bet is if you can trigger this bonus during any of the other bonus rounds to get bigger multipliers.
