Players are presented with a grid of colored blocks, each with a specific shape and size, which move back and forth in a continuous flow. The goal is to clear the entire grid by strategically swapping adjacent blocks to create horizontal and vertical lines.
The game's objective is to keep the grid clear by continuously swapping blocks to create lines without interrupting the flow of new blocks moving in. The grid remains in constant motion, requiring players to think quickly and act efficiently to maintain the cleared space.
