Home Pipe Water Puzzle is a game where you complete minigames that require strategic logical thinking. Each "day" in the game consists of three different puzzles with three rounds each. These puzzles can be any of the following:
Connecting pipes to provide water
Digging a path in the ground to give slime to a mutant
Remove pins to rob a bank via the pipes
Rotating pipes to fill up a minecart with treasure
Using flame retardant/soapy water to put out fires and wash clothes
In some cases, an alternate source such as sewage or gasoline is included in the minigame. Naturally using these sources instead of the right one will lead to a loss and you'll have to do the round over again.
You can obtain gold coins and skins while playing but must watch a video to claim them. This applies to rewards offered by the bonus spin as well.
Golden keys will be collected as you play, giving you another bonus round where you open three treasure chests. You will need to watch a video to claim your prizes in this case as well.
