Why did my shot not count as an attempt?

A pull shorter than a small threshold is treated as a stray tap, so it is not charged against your ten.

The ball went through the hoop — why no score?

It must pass downwards through the rim, between the two ends. Coming up from underneath, or crossing outside the ends, does not count.

In Basketball you pull back from the ball like a slingshot and release. The ball flies in an arc; the only thing pulling it down is gravity.

Drag back, release to shoot
Press on the ball and drag away from the hoop. The further you pull, the harder the throw, and the ball goes the opposite way to your drag. A short pull is treated as a mis-tap and does not count as an attempt.
The flight is a plain arc
Once the ball leaves, the only force on it is a constant downward pull. It does not curve, slow down sideways or drift — so a shot that misses tells you something you can actually correct next time.
A score means passing down through the rim
The ball has to cross the rim's line travelling downwards, and cross it between the two ends of the rim. Passing up through the hoop from below does not count, and neither does passing beside it. A ball that clips the very end of the rim still counts as inside.
An attempt is one release
Each release counts as one of your ten, whether it goes in or not. The attempt ends when the ball reaches the floor or leaves the court.
The launch spot shifts a little each round
The hoop stays put, but the ball starts from a slightly different place each time you begin. If the launch point were fixed, one memorised drag would be worth all ten attempts.
A faint arc shows your aim
While you are still holding, a dashed arc previews roughly where the ball will head. It is short on purpose — enough to aim with, not enough to solve the shot for you.

The ball has to drop through
A shot counts only if the ball crosses the rim line from above while travelling downwards, and nothing flatter than about sixty degrees from the launch spot can do it. A hard flat drive arrives still rising and passes out the back, so aim above the hoop and let gravity bring it down instead of throwing at the rim.
Power has a narrow band
Full power would need a drag of about one hundred and sixty-seven pixels, but every shot that actually scores falls between roughly one hundred and thirteen and one hundred and fifty-two. Pulling to the limit is therefore always too hard, and the difference that matters is a few pixels of drag rather than a large change.
A steeper arc forgives more
The range of drags that scores widens as the angle steepens: near sixty degrees only a couple of lengths work, around seventy several do, and near eighty a dozen do. So when a shot is close, lifting the arc is the safer correction than trimming power, because it widens the band that still goes in.
