Stone Building (Conveyor Belts)
The stone building is both a puzzle challenge and a platforming challenge. When you first enter, you will be unable to reach the puzzles on the upper levels (the ones that partially power the laser). Of course, before worrying about getting up there, you’ll need to open the door first.
Do not let the simplicity of the door’s puzzles fool you though. The Witness can be quite deceptive at times. The puzzles within have an entirely different rule-set, so lets get into those. When you enter you’ll need to use the conveyor belt to get to the upper level. The solutions is:
You should note that the belt moves, so be ready to jump onto it. If you miss your chance just lower it back down by using the lower path on this puzzle. You’ll next need to power up another switch to raise one more platform. These puzzles include asterisks. The rules for the asterisk is that they must erase one error. So you’ll have to purposely leave a mistake within its cut off section. The solutions to the panel are:
This will power the next platform (take the high road on the switch), and lead you to the stone building’s challenging puzzles. Keep in mind the rule of the asterisk. Colors should be in pairs, so you’ll need to keep a lone green with the asterisk, within the puzzles. Here are the solutions:
This will power up the next puzzle, which in turn powers up one more.
With that, you’ve provided half of the necessary power to the laser. Before leaving head back to the first long panel of puzzles on this upper level (the difficult ones) and activate the stairs near them. This will make it easier to get up here again if you need to. Also open all the gates and doors to the building on the ground level (they use simple slide locks).
Now it’s time to head to the boathouse.
