This is a pipe - connecting game. Players need to rotate and move red pipe parts within a limited time to splice them with blue pipes to form a complete water - passing pipe. During the process, they should avoid pipe obstacles with locks and can also use green 标识 props marked with "×2" and "×4" to help connect the pipes. Finally, let the water pass through the combined pipes smoothly, which tests spatial thinking and time management skills and experiences the interesting challenge of pipe splicing.
