Patent abstract
The present invention provides a pattern-changing walk path on top of which some groove lines and some raised ridges or dots form an anti-skidding layer for children's play and games. The modular design may be disassembled into the units for storage, taking up little room since they can be stacked together, and can be securely attached to one another when put together for use.
