Block Out Level 90 Walkthrough
Block Out Level 90 is an open-tray board built around one shared center well. Clear the first yellow shapes without sealing that middle space, then let the red shelf, green staircase, and later yellow blocks rotate through the same opening until the arena empties.

How to Solve Block Out Level 90 — Full Solution
- Move the upper yellow L-shape out first so the top half of the arena opens.
- Clear the lower-left green square and the first yellow square without filling the center well.
- When the red shelf appears in the middle, rotate it through the open center instead of pinning it to a side wall.
- Let the green staircase and blue foot-shaped pieces cross the middle one at a time while the side exits stay clear.
- Save the bulkier yellow shapes for after the red and green traffic has thinned.
- Finish with the last red L-piece and the remaining yellow blocks once the middle of the tray is empty again.
Colors in this level:
Yellow, Orange, Red, Green, Blue
Common Mistakes to Avoid
- Stuffing pieces into the lower corners and closing the center well.
- Treating Level 90 like a channel puzzle instead of an open-tray rotation board.
Quick Tips for Block Out Level 90 (spoiler-free)
- Treat the middle of the tray like reserved airspace. Do not park pieces there.
- The side locks matter only when you let traffic bunch up next to them.
- If the board feels stuck, look for the color with the cleanest path and use that to regain space.
Board notes 5 details
- Layout
- There are no chambers here, just an open arena. A yellow L-shape stands near the top-left, another yellow shape and a green square begin lower in the tray, and locked purple posts narrow both bottom side exits. Later waves bring in a red shelf, green staircases, blue foot-shaped pieces, and more yellow polyominoes.
- Goal
- The center well is the real resource. Early yellow and green pieces must leave in a way that keeps that middle space free, because every later wave has to cross the same open lane on the way to the side exits.
- Opening
- Lead with the upper yellow L-shape, then make room for the lower green square and first yellow square. As the arena widens, rotate the red shelf and green staircase through the middle one at a time.
- Danger Zone
- If the center well closes, later red and blue pieces bounce between the lower side locks instead of leaving cleanly. The board is wide, but it still has one critical breathing lane.
- Mechanics
- Level 90 is a pure open-tray routing puzzle. The difficulty comes from preserving one shared center well across several different waves of polyominoes.
Frequently Asked Questions
What is the real trick in Block Out Level 90?
Keeping the center well open. Almost every later shape has to rotate through that same square of space before it can reach a side exit.
Why do the side exits feel cramped in Level 90?
Because the locked purple posts narrow them. They are manageable only if you keep traffic moving through the middle instead of stacking shapes on the walls.
