Free Web Game - Stack Attack

Stack Attack is a puzzle game similar to the arcade classic game Klax.

Watch a sample video of level 1, and look below for game rules.



Game Rules

Using the arrow keys, move the tray to catch the blocks. The last block on the tray is the first one off. Use the space bar to drop blocks into the pit. Make lines of 3 or more of the same color vertically, horizontally, or diagonally. You can throw a block back on the belt using the up arrow key, and holding the down arrow key makes the belt move faster.

Game Level Goals

There are a few different types of game levels:
  • Horizonals: Only horizonal lines count towards the goal.
  • Diagonals: Only diagonal lines count towards the goal.
  • Lines: All lines count, horizontal, vertical, or diagonal.
  • Points: Score a certain number of points to reach your goal.
  • Catches: Catch a certain number of blocks to reach your goal.

Game Scoring

Scoring is separate from reaching the goal for all game levels except Points levels.
  • Vertical line: 100 points
  • Horizontal line: 1000 points
  • Diagonal line: 5000 points
These scores are for lines made of 3 blocks. 4 block likes are worth double, and 5 block lines are worth 4 times as much.

If you make two or more lines at once, or create a combo, bonus multipliers go way up.

Be creative in your strategies for playing this game, think about ways to get lots of points while completing the levels.
