The volatility is medium and the return to players comes in at 94.0% at the most trusted casinos online.

Wild transformations happen at any random time, turning either of the two high paying characters into the scary Monster accompanied by some impressive animations.

The big switches that tend to appear in any classic horror movie land in green, blue, or red versions, zapping energy to matching switches on the top of the 3 Wonders Monster Pays online slot reels. Randomly, they trigger respins where just Electric Balls with money values, switch scatter symbols, or blanks appear. You get three respins where any orbs lock in place as they reset the spin counter and free games run until there are three in a row with just blanks, or Electric Balls fill the grid.

Here's what happens in each of these popular online slot bonus rounds –

• Green Scatter - Electric Ball prizes can be x0.2, x0.4, x0.8, x1,2, x2, x3, x4, or x10. Whenever the green switch appears, it upgrades the values of any surrounding Electric Balls by x0.2 or x0.4 before revealing a prize for itself.

• Blue Scatter - This game comes with boosted prize values of x4, x6, x8, x10, x12, or x16.

• Red Scatter - Any red switches collect the values of all money symbols in view, leaving them in place for further collections if more appear, or at the end.

Once you run out of spins, all Electric Balls on the reels of the 3 Wonders Monster Pays slot machine pay their prizes which can hit a monster-size 10,000x your stake.

If you like the theme , be sure to try the Frankenslots Monster online slot from Betsoft and the Mad Scientist slot machine by Roundstone International.
