In Stack Battle.io, you get to build super cool towers with colorful blocks! You control your block by moving it left and right to stack it high, but watch out! Other players are trying to knock your tower down while building theirs. You can push them away or try to outsmart them to be the tallest! When you reach the top, you can jump around like a crazy hero! The game is all about strategy and fun, and the best part is trying to be the last one standing with the highest tower. It’s a battle of blocks, and it’s awesome!
