Senpa.io unlocked is an Agar-style free online game that forces you to move around a huge arena trying to gather all the scattered masses to grow your size. As you reach a bigger size, it will be a piece of cake for you to eat other cells and clear them out of the arena. You must hunt down the smaller ones while staying away from the bigger ones. Do your best to get to the highest rank on the leaderboard. Much fun with Senpa.io online!
