Sparkball is a MOBA style action sports game. And this game is a part of the Sparkadia ecosystem. You may feel like playing the mobile legends with the rugby style game in the same. The game has ascension update that would be a good for you to try out over the weekend. You may notice that this short weekend gameplay would be worth playing.
You would be needing the 3MATIC minimum to play around the game. The team is holding the ascension weekend - June 30 to July 3rd. They even made the tweet about the same.
I like how they are turning the football and MOBA concept together. Though it wont be long term play type of the game but we have pretty cool graphics and the game idea which is kind of experimental. I am sure there are some of the type of people who would be playing the game and may enjoy how the game works around.

You may check out the official game-play for the sparkball here.
This MOBA style game is pretty cool and I feel like this game has some future based on how it is so far. There are going to be other prizes too which involves the amazon gift cards and also there would be raffle based prizes that you would find. And details related to that would be shared in the discord of this games channel.
