Mathematically backwards

Seven colors.
Seven paths.
One ending.

It looks like pure chaos. It isn't: the code starts at the ending and calculates backwards, so all seven colors always finish together.

🎬 Make your own video

Choose in 3 steps, then pick a color at the video to start.

1World

A new world means a new video: the code searches again.

2Colors

🎨 Make your own rainbow

New colors show at once, in the same video.

3Characters & animals

The animals the colors bounce off at the start. They show at once, in the same video.

Ready? Now pick a color at the video!

Tap a character to start

Which color finishes its arc first? Tap the character you think finishes first: then the video starts. Right guess: confetti and +5 coins in the pot!

1
The ending comes first

The code starts with the finish: the arc. Every color gets its own band in the arc, and a moment to reach it.
2
Calculate backwards

From that ending, the math runs time backwards: through every bounce off the bars, the walls and the floor, back to where each color has to start.
3
Search

Not every world works. The code tries layout after layout and throws away every one where a path doesn't fit, until all seven fit at once.
4
Play it forwards

Then the video plays forwards. It looks like chaos, but every bounce was calculated: each color follows its own path… and they always end together.
