Quick answer
Find the complete bright line and both of its endpoints before opening the crossing. Compare the linked recording for the release order, keeping the red character away while the line crosses its intended route. A circular chamber contains a blue beam emitter and a green creature; black diagonal ledges leave a lower-right exit toward a red ball.

Step-by-step
Locate the red ball and every green creature before cutting. Keep the starting support until the route below is ready.
Find the complete bright line and both of its endpoints before opening the crossing. Compare the linked recording for the release order, keeping the red character away while the line crosses its intended route.
Round the bottom of the turn instead of leaving a sharp corner. A smooth floor helps the ball follow the bend.
Keep an unbroken descending slope on the approach. A flat shelf or upward step can remove the momentum needed for the next turn.
Check the full target route after the last movement, including pockets above the final drop. If a creature remains, identify the earliest turn that missed it and change that local approach on the next attempt.
Tips
- Check the bright line before each release, including the return path. A route that is safe in one visible frame can change when surrounding objects move.
- Keep a shallow outer wall around the bend. It gives the red character a surface to follow instead of allowing a free fall past the pocket.
- Keep the landing slope continuous. Small upward steps near the exit can stop the character even when the preceding descent provided enough speed.
Common mistakes
- Opening the final outlet before checking higher target pockets can leave a creature above the character with no route back. Inspect the side entrances before making that irreversible drop.
- Removing several supports in one swipe makes the release order unpredictable. When a moving piece occupies the route, wait for it to settle before changing nearby sand.
Frequently asked questions
What should I check at the bright-line crossing?
A circular chamber contains a blue beam emitter and a green creature; black diagonal ledges leave a lower-right exit toward a red ball. The crossing depends on the visible line and the positions of nearby objects. Compare the moment just before release in the recording. If your board differs, hold the starting support instead of assuming the same crossing is safe.
How do I keep the character in the curved passage?
An abrupt corner can redirect the character away from the next pocket. Keep the bend connected to its receiving floor; when the first attempt misses, adjust the approach angle rather than deepening the entire chamber.
Why can the landing slope stop the character?
Keep the landing slope continuous. Small upward steps near the exit can stop the character even when the preceding descent provided enough speed.
