Shelltastic Wins Slots

It's animated and interactive, with moving graphics and an adorable design, This is a RealTime Gaming slot, and RTP has an impeccable reputation, being one of the longstanding software developers out there, having many popular games under their belt.

Everything you need to navigate the vast and bottomless sea is located within the transparent black bar at the bottom of the board.

You can use the max bet button as well as the auto spin button if you choose, and you can set it to auto-spin from 5 to 100 times. You can also increase the speed by which the reel operates. It plays cheerful background music that reminds me a little of 'under the sea' from The Little Mermaid.
Symbols
The highest premium symbol on the board is the golden shell, which is worth 1000 credits. The next highest-valued symbol is the purple swirling shell, valued at 500 credits. The green swirling shell is valued at 300 credits, and the red shell is worth 240 credits. The lower-paying symbols are the coins with different symbols, with the highest-paying coin being (quite morbidly) the one with the little skull on it. After that, there is a silver coin symbol with a crown, followed by the green symbol with the hook, the red symbol with the fish bone, and an anchor symbol is the lowest on the board. You can win up to 12 of a kind per symbol.
