A missed shot contains more information than the final zero. The useful question is which part of the flight failed: reaching hoop height, arriving at the opening while descending, or surviving a collision. Learn to name that failure before choosing the next setting.
Compare two controlled shots →
Read the flight in three stages
First watch the climb. Did the ball rise above the hoop, or reach the area without enough height? Next watch its descent near the opening. A ball passing the hoop on its way up is not a made basket. Finally, watch any rim or backboard contact through to the end. A collision may change the route enough to rescue a shot that would otherwise miss.
These stages separate different problems that can all produce the same score. A high ball that falls short is not the same error as a flat ball striking the near rim. Write a short description such as “above rim, descending left of opening” instead of only “miss.” That description gives the next trial a specific question to answer.
Treat angle and power as different controls
At a fixed power, raising the angle puts more of the launch speed into upward movement and less into movement toward the hoop. The ball may rise higher yet fail to reach the opening at the right moment. “Higher arc” is therefore not another name for “better shot.”
At a fixed angle, raising power increases both the upward and forward components. It changes the entire path, not just the final horizontal position. Use a small comparison to discover which way the approach moves in the region you are testing; do not assume a correction will have the same effect at every angle.
Separate a repeatable setting from a lucky-looking result
The shot rules contain no random accuracy roll. A trial with the same settings and the same simulation stepping is deterministic. The live browser advances collisions in small time steps, however, so a result very close to a rim boundary need not be identical across every device or frame schedule. The practice comparison can hold the stepping fixed while you study the controls.
A backboard basket still earns the game’s two points. For learning, tag it separately from an entry without a rebound. A setting that repeatedly approaches the middle of the opening provides clearer feedback than one whose outcome turns on a glancing edge contact. This is a practical testing preference, not a claim that a bank shot is invalid.
Build a small neighbourhood around a candidate
Start with a setting that reaches the hoop area. Hold its power and compare the angle just below, at and just above your candidate. Then restore the candidate angle and compare nearby powers. Keep the records separate so you know which control caused the change.
Once a candidate works, test a neighbouring setting deliberately. If every nearby comparison abruptly misses, you have found a narrow useful region rather than a broadly forgiving one. Return to the successful setting for a scoring round, or continue studying the narrow region. Do not discard a useful result simply because a later experiment was intentionally worse.
The game checks the five-basket goal after all ten attempts have ended. Use practice comparisons to answer one question; use a complete round to measure the outcome you actually care about. Mixing exploration with an attempt at a best score makes those two goals harder to assess.
Two experiments to try
EXPERIMENT 1
An angle-only comparison
Use the shot comparison with power fixed at 98. Test angles 64°, 66° and 68° from the same launch position.
- Predict whether each change will make the climb steeper or flatter before launching.
- Run all three trials at the comparison tool’s fixed simulation setting. Let each ball finish.
- Record the approach and any collision as well as made or missed. Repeat the unchanged middle trial as a control.
What to observe
Look for how the crossing position changes, not just which angle wins the three-shot comparison.
Why this comparison is useful
The starting state and power are controlled. The differing angle explains the differing model trajectories; the experiment does not establish a universal shooting setting for other games or collision timings.
Your change and observation:
EXPERIMENT 2
Test the width of a useful power range
Choose an angle from your first comparison that sends the ball through or close to the opening.
- Hold that angle throughout. Test powers 96, 98 and 100 as separate fresh shots.
- Describe the difference between a clean opening entry, a rim collision and a backboard return.
- Pick one trial, repeat it unchanged, and then return to the original comparison rather than making an unrecorded two-control adjustment.
What to observe
A made shot and a nearby miss can identify a boundary worth examining more closely.
Why this comparison is useful
Three trials are a local comparison, not a success-rate estimate. The goal is to locate how this model’s path changes near a candidate setting.
Your change and observation:
Check your decision
One trial falls left of the opening while descending. You change both angle and power and the next trial scores. What has that comparison established?
Answer and explanations
Keep the successful combination, then compare one control at a time if you want to understand why it worked.
- Both changes were necessary.
Not supported. Changing both controls together cannot show whether either change alone would have worked.
- The new combination worked, but the contribution of each control is unresolved.
Supported. Now hold one control fixed and compare to separate their effects.
- A higher arc always scores.
Not supported. The comparison neither isolates angle nor covers other launch settings.
Your next practice session
Play a fresh ten-shot round using one selected setting. Keep experiments for a separate round so your score has a clear interpretation.
Scope and checks
This guide describes the current Playfield implementation. The experiments are proposed ways to practise, not measured player results. Rules were checked against the game source; the written scenarios and explanations received a separate review.
