WormsZone.io

WormsZone is an offline version of the "IO" snake game. As you cannot compete with other people, you can enjoy smooth gameplay without the need for a network.  

As you'll be slithering through the board, you'll find several different power-ups, including score multiplier and zoom-out. You'll also be able to collect premium coins as you play or kill bots.

Coins could be spent on a wide range of customizations - skins, colors, or even parts of facial expressions. Additionally, you'll be able to purchase mentioned power-ups to make the game easier.

WormsZone doesn't deviate much from slither-like simple graphics. Still, the collectible items are more detailed - and you're even able to change the food set to another range of objects.

The game will force you to watch ads after matches and offer many options to watch more ads for small rewards. Fortunately, there's an option to purchase no-ads mode.
