The game Alien Blocks presents a puzzle challenge where players are tasked with clearing a grid of randomly arranged blocks of different shapes and colors. To accomplish this, players must swap adjacent blocks to create a solid line of blocks without gaps.
The objective is to create rows of the same-colored blocks without gaps, which will then disappear from the grid. The player's ability to think strategically is called upon, as they must carefully plan each move to achieve their goal. As the game progresses, the blocks will increasingly fill the grid, making the challenge more complex.
The game runs directly in the browser, requiring no download or registration process. The gameplay is straightforward, focusing on problem-solving and strategy, as players must make the best use of their moves to clear the grid. With a growing grid, the challenge advances, testing the player's ability to manipulate the blocks effectively.
