Wow, I just finished a session playing a fun, new game called FGP (short for 'Fun game Play') Plumber. Overall, I recommend you play it for the following reasons. Let's jump right into it!
You start off at the main menu of the game. Once you click 'Play' you can select 1 of 3 options which are Classic Mode, Time Mode, or More games. I started with Classic Mode; you start at Level 1 and the other levels are locked until you complete the last one.
Your goal is to attach pipes with spurting water into the other pipe parts... until they are all linked and there is no more leaking water. You can click each pipe section to turn them in different directions.
I recommend this game, it's not only fun but also stimulates your brain to correctly fit the pipes and move through each level. 10/10 great game for spare time!
