The House: what opens every zone
Four zones are open from the start. The Front Yard and the Porch together open the Rooftop, the Rooftop opens the Backyard, the Pool and the Maze, the Maze opens the Farm, and the Farm is followed by the Basement.
- Front Yard+Porch
- Rooftop
- PoolBackyardMaze
- Farm
- Basement
In the order a run goes
Open from the start
Front YardPorchCourtShed
None of these needs anything. The Garage sits behind a closed door until you press the red button in the Shed. Where the button is
Front YardandPorchRooftop
This is the gate people get wrong. Finishing the Front Yard on its own opens nothing; so does finishing the Porch on its own. The second of the two is what says “Unlocked: Rooftop”.
Rico9 did them the other way round, Porch first, and got the same result. Rico9, 0:39 Rico9, 1:32

Front Yard first: only COMPLETED!. Screenshot: Yoiikit, 1:20 
Then the Porch: Rooftop unlocked. Screenshot: Yoiikit, 1:23 RooftopPoolBackyardMaze
Looking for the Backyard? Clean the Rooftop. It opens the Backyard, the Pool and the Maze in one go. Yoiikit, 1:49 ViewSIM, 10:45
Your quest line switches to “Unlock Backyard” as soon as the Rooftop opens, so it can look as if the Backyard should already be yours. It is the Rooftop itself you have to finish.

One zone, three unlocks. Screenshot: Yoiikit, 1:49 MazeFarm
The Farm only opens from the Maze. Yoiikit, 4:47 ViewSIM, 13:24
The first Duck Bot part is in the Farm, on the wooden bench.

In three separate runs, “Unlocked: Basement” came up the moment the Farm was done. By then every other zone was clean as well, which fits what the basement doors tell you before that: “Complete all the zones to escape!” Yoiikit, 5:50 ViewSIM, 14:12 Rico9, 3:01 Flush, 0:53
Clearing the basement opens a passage in its wall: the way to the Secret Ending. How to clear the basement

Every zone adds 10% to your cash boost
It does not matter which zone. Each one you finish adds another 10%, so by the last of the 11 zones, the Basement, it reads +110%.
