This is a puzzle game suitable for all ages. It can develop the intelligence of kindergarten children, prevent Alzheimer's disease for the elderly, and students and office workers can enjoy the fun of challenge. However, you must start from the simple level and progress step by step, otherwise you could be mad and collapsed.

You can move the blocks on surface with mouse or keyboard, and rotate and flip the blocks to the desired position with menu buttons or keyboard shortcuts. In 3D mode, a "pick up" mode (P) is specially designed for easy placement. By selecting specific end points of the block, it can be automatically rotated to the desired position.

In order to increase the difficulty for advanced players, the placement time is recorded to see who can complete levels in the fastest time.

I hope everyone can enjoy the game! Certainly, I did, and my kids had fun, too.
