What makes Pipeful Sunday a bit more difficult than other pipe puzzles is that you cannot choose the pipe segment to place on the board. You must always take the most recent one the game gives you, and put it somewhere (similar to Tetris that way). Since the board space is limited, and since points will be deducted from your score if you replace an existing pipe segment on the board with a new one, you must carefully plan your route ahead of time to minimize the deductions. Higher levels game pose more obstacles, such as fixed walls you must run your pipes around.

All in all, Pipeful Sunday is a challenging and enjoyable puzzler. It is not hard to finish a level, but it is difficult to get high scores, i.e. minimize the number of tile replacements and your time spent. If you enjoy reflex-based puzzlers, this freeware underdogs from Japan will give you plenty of brain cell exercise. Thumbs up!
