Create Huge Amounts of Energy Before Aliens Steal It

As a Bloxter, it's up to you to create energy in a block reactor. You must arrange colored blocks so that they react and don't overfill the reactor. But watch out for aliens that may interfere with your reactions!

Tetris fans will enjoy this similar falling blocks puzzle game with more than 30 puzzle board types to choose from.

Arrange Blocks to Make Groups

Groups of four different-colored blocks arranged in a square fall from the top of the screen. You can rotate and move the blocks. The goal is to match three or more of the same colored blocks in horizontal, vertical or diagonal lines. Then the blocks will react and disappear. It's game over once any column of blocks hits the top of the screen.

Play Puzzle mode without aliens or Arcade mode where Vader aliens suck energy from some blocks or change their colors. Choose from more than 30 board types in Arcade mode such as Stripes, where you must bring down tall columns of blocks of alternating colors, and many other tough puzzles.

Infinitely Replayable and Great for Everyone

This game has something for everyone because Puzzle mode is easy to learn while Arcade mode offers a bigger challenge. This game is infinitely replayable with the many boards and the challenge to keep beating your former high scores. Submit your scores to compare them with other players and keep playing until you reach the top!

The world needs energy! Start making the blocks react now before the aliens suck away all the energy in Bloxter!
