More about this game
Your goal is to crack the server by placing four specific block shapes onto a 4x4 circuit board. Each row and column displays glowing bars indicating exactly how many cells must be filled in that line. The difficulty increases as you clear stages, introducing more complex layouts with fixed locked cells and forbidden zones where blocks cannot be placed. A run continues as long as you keep solving grids, earning gold to buy new terminal skins and effects.
Tips
- If you get stuck, wait 18 seconds for a hint pulse to show you where one unplaced block belongs.
- Pay attention to fixed locked cells; they already count toward the row and column totals.
- Use the reset button to instantly clear the grid if your current layout is completely blocked.
FAQ
- Why did my block flash red when I placed it?
- A block flashes red and returns to the tray if it overlaps another block, hits a forbidden cell, or causes a row or column to exceed its target count.
- How do I unlock new colors?
- You earn gold for every grid you crack. Tap the Shop button to spend your gold on new terminal colors like Cyan, Magenta, or Amber, and new visual effects.
- Can I rotate a block after placing it?
- Yes, you can double-tap a block that is already on the grid to rotate it in place, as long as the new rotation doesn't break any placement rules.
