Quick tips

  1. Protect the green stem.
  2. The lower room is support work for the upper boss.
  3. Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.

Step-by-step solution

Step-by-step solution

  1. 1

    Move 1

    Clear space around the yellow bottom gate in the lower room so the first counters begin to fall.

  2. 2

    Move 2

    Rotate the red and blue lower-room blocks without pinning the central green stem.

  3. 3

    Move 3

    Keep the purple `5` parked in the upper chamber while the top frame counters drop.

  4. 4

    Move 4

    Use the lower room to keep feeding the sides of the upper chamber until the boss frame is almost open.

  5. 5

    Move 5

    Free the green stem only after the lower room has enough empty space to absorb the next moves.

  6. 6

    Move 6

    Let the upper chamber finish once the purple `5` block is no longer locked by the frame.

  7. 7

    Move 7

    End with the last lower-room colors after the boss block has already cleared.

Common failure points

Blocking the green connector with a lower-room color block.

Trying to move the purple `5` while the frame counters are still high.
