Block Out Level 138 lines up three orange-bordered tubes — `7`, `9`, `13` — as the board's only progress trackers, fed from a multicolor base grid through a header `2` device. The right-column `3` counter and base slabs must align before the tubes accept input. Push the purple cluster before the header fires and a lone red block drifts into the `9` tube's feed lane, stalling the longest counter.

Video walkthrough

Quick tips

  1. Clear the isolated red bottom-center block last — doing it early overfills the 13 tube.
  2. Feed the right-side yellow/ blue/ red stack only after the 7 column hits zero.
  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 the bottom-left blue square and red horizontal pair through the blue left-arrow lane to start the left 7 column.

  2. 2

    Move 2

    Slide the center yellow horizontal block rightward to feed the middle 9 column without touching the right-side 2 counter.

  3. 3

    Move 3

    Break the right-side yellow/ blue/ red stack through the green right-arrow lane once the 7 column hits zero.

  4. 4

    Move 4

    Feed the remaining purple and cyan base scraps upward into the right 13 column.

  5. 5

    Move 5

    Spend the header 2 device and red segmented bar after all three column circles clear.

  6. 6

    Move 6

    Drain the right orange-column 3 counter and exit the last red singleton through the red bottom-arrow for the board clear.

Common failure points

Clearing the bottom-center red block before the header 2 spends, overfilling the 13 tube.

Feeding the right-side stack before the 7 column clears, locking the green right-arrow lane.
