Crates木箱

Drop 3 nearby boxes to open it!

How it works

  • A Crate is a wooden blocker on the upper board hiding 4 marble boxes behind it, blocking both information and access.
  • To open it, drop 3 nearby boxes around it (from Top 2, Bottom 2, Left 2, or Right 2); the third drop breaks the Crate.
  • It can hide Normal Boxes, Hidden Boxes, needed colors, useless colors, or mixed boxes — you may break one blocker and get another mystery.
  • You drop the third trigger, not the Crate itself, so it forces you to spend moves and belt space before knowing if the reward helps.
Pro tip

Read the bottom first, find useful visible colors, drop only nearby boxes whose marbles have a place to go, and save the third drop until the conveyor has space. When a Crate needs one more hit, wait until a matching bottom box is almost ready, then break it — clearing the crate and the bottom together. Only open it when the move also helps your bottom slots; Crates punish blind tapping.
