This review comes from someone who doesn't really play games on phone.
Because of how they are behind many ads and micro-transactions, but. This game is something else.
Never gives ads unless you want to see to double your reward.Can be played without internet.
Kinda grindy but it's worth it since there are so many content in the game.
Graphics are smooth and great. No lag at all on my low-mid tier phone. 60FPS at all times.
Gameplay is easy to understand yet fun.
Just give it a try. If you like pokémon, you might like it. It's kind of like that but you are throwing your pokémons into arena to fight all together.
