By @谢明轩
Drag blocks onto a grid to build a single connected shape that is perfectly symmetrical across the center line.
How to play
- Select a block from the bottom tray and drag it toward the main grid.
- Position the block so it aligns with the grid cells and release to snap it into place.
- Place all remaining blocks without overlapping or crossing the outer boundaries of the board.
- Ensure every block touches at least one other block to form a single connected structure.
- Arrange the final shape so both sides perfectly mirror each other across the central vertical line.

More about this game
Your goal is to arrange a set of blocks on the board to create a single connected shape that mirrors itself across the glowing central axis. You select pieces from the tray and drop them onto the grid without overlapping. The game features 10 levels, with the grid expanding from 6x4 to 8x7 and the number of blocks increasing up to seven. A level ends when all pieces are placed and the resulting structure is fully connected and symmetrical.
Tips
- Start by placing blocks directly against the central axis, as this establishes a solid foundation for mirroring shapes on both sides.
- Count the total grid cells of your blocks; if you have an odd number of cells, at least one block must cross the center line.
- Use the reset button if you get stuck, especially in the final level where you must manage 7 different blocks on an 8x7 grid.
Questions
Why did my block return to the tray?
If you try to place a block outside the grid boundaries or overlapping an already placed block, it will flash red and automatically return to its home slot in the tray.
How many levels are there?
There are exactly 10 levels to complete. The grid starts at a simple 6x4 size and gradually expands to an 8x7 board for the final challenge.
Does the shape have to be in the center?
Yes, the final connected shape must be perfectly symmetrical across the glowing vertical line in the middle of the board, meaning both sides must mirror each other exactly.
