How to play

1. Steer the falling piece

Use β—€ β–Ά or tap a bin. β–Ό nudges it down. Drop slams it into the column.

2. Right bin = clean stack

A correct sort lands as a clean item and counts toward the level goal. Early levels are short β€” Level 1 is only 5 clean sorts.

3. Wrong bin = contamination

The piece still lands, but it dirties that stack. Dirty stacks cannot go out on the truck. Five correct sorts in a row send a sweeper that pulls one dirty piece out.

4. Clear the level, then go faster

Each level has a short clean-sort goal. Level 1 is 5 drops. Later levels add families and speed. Overflow or 8 contaminations still end the run.

Same families as Sortify

Paper and cardboard share the paper bin. Rigid plastics share one plastics bin: bottles, milk jugs, and yogurt cups. Soft bags and foam are still trash β€” they jam the machines.

Rules vary by town. This test copy follows Sortify’s families.
