A girl tries a spinning teacup ride, beloved at amusement parks across the world. There are four saucers on the ride's base and four cups on each saucer.

Before you open a hint
Count all three rotations. The question asks which way the rider faces, not where her cup ends up on the ride.
Hints, one at a time
These are the game's own hints, word for word from the North American version and in the same order. Open only the next one you need. In the game, Hints 1 to 3 cost one hint coin each and the Super Hint costs two.
Hint 1
You know it takes 20 seconds to complete one rotation. That means in 15 seconds, you'll get a three-quarter rotation. So three-quarter rotations each for the base, saucer, and cup gives you...
That's a bit confusing, isn't it? Isn't there an easier way?
Hint 2
The girl is sitting in the cup, so you'll need to add up all the rotations of the base, saucer, and cup. In that case, you can express the problem in simple math.
Each makes one three-quarter rotation, and one rotation is 360 degrees, so it's 270 degrees each.
Hint 3
Calculate the total rotations of the base, cup, and saucer. That's 810 degrees (270 degrees times 3.)
A full rotation is 360 degrees, and two full rotations will put you at 720 degrees. You can then go an additional 90 degrees from there.
Where would that leave the girl facing?
Super Hint
You'll end up with two full rotations and a 90-degree rotation. That means you only need to think about the 90-degree rotation.
In other words: the direction she'll be facing is just a one-quarter rotation from her starting position. Where is that?
Answer and full solution
The answer and the worked explanation are hidden below. Open them when you are ready.
Show the answer
Choose south (S). In 15 seconds, each part makes 15/20 of a full turn: 270° clockwise. Add the base, saucer and cup rotations: 270° + 270° + 270° = 810°.
Two full turns account for 720°, leaving 90° clockwise. Starting from east, a quarter-turn clockwise points south.
Counting only the cup gives the wrong result. All three rotating parts change her facing direction.
Picarats, hints and hint coins
