The sample covers 64.1% of a 20x28 lattice: 5 colours, 0 empty rows and 28 separate colour groups.
blue 27.9% of the sample
Spread across the sampled board rather than parked in one corner.
red 21.3% of the sample
Spread across the sampled board rather than parked in one corner.
pale blue 18.8% of the sample
Concentrated in the central half of the sample, so these pieces have to cross the busiest lanes.
green 13.7% of the sample
Spread across the sampled board rather than parked in one corner.
orange 9.4% of the sample
Spread across the sampled board rather than parked in one corner.
navy 8.9% of the sample
Dark board backing — empty cells or mechanism panels, not a coloured block.

How to read this board
Start from the largest colour: blue
Blue covers 27.9% of the sampled board — more than any other colour. It has the most pieces to route, so clear it early once its door is reachable instead of leaving it until the board is tight.
Protect the middle: pale blue
Pale blue sits mostly in the central half of the sample. Moving it will cross routes other colours still need, so keep that part of the board as clear as the level allows.
The board starts crowded
Only 8.9% of the sample is dark background. With little spare space, every parked block costs a lane; plan two or three moves ahead before sliding into the centre.
5 measured colours
The sample contains 5 main colours. Fewer colours means fewer door groups to track, but the remaining pieces can still block each other; clear one colour at a time.
How the Level 135 clear works
The sample fills 64.1% of its 20x28 lattice and splits into 5 colours and 28 groups. The pieces are spread across the sampled rows (32.6% top, 37.3% middle, 30.1% bottom) rather than stacked in one band. Blue is the most divided colour, with 9 separate groups in the sample. Space is shared, so the order matters more than the speed: a block parked in a doorway can wall off another colour completely.
Level 135 sits in the Intermediate tier and in the 121–160 block of this guide. Mid-game boards start crossing lanes and adding a second color on the same route. The extra challenge is not speed but sequencing — clear the block whose path disappears first. The sample has no empty rows and no full-width corridor, so spare space is limited.
Strategy note 1
The sample has no empty rows, so every move has to open the next one. Plan two moves ahead before sliding into the middle.
Strategy note 2
Blue is split into 9 groups. Clear the group closest to its door first; the far groups stay blocked until that run is finished.
Strategy note 3
64.1% of the sample is covered: enough room for one waiting lane, not two.
Strategy note 4
Use the outer edges as waiting space; the centre is the route you will need again.
Strategy note 5
Clear the edge pieces before the middle ones; the centre is where every route has to cross.

Block Out Level 135 — frequently asked questions
- What colours are on the Block Out Level 135 board?
- The board image on this page breaks down into 5 main colours: blue (27.9%), red (21.3%), pale blue (18.8%), green (13.7%), orange (9.4%). The names are read off the measured hex values shown beside each swatch, so they can differ from the name the game gives the same block.
- Which colour covers the most of the Level 135 board?
- Blue is the largest measured colour at 27.9% of the sample. That makes it the colour with the most pieces to route, so it is usually the one worth clearing early once its door is open.
- How much of the Level 135 board is empty?
- The dark board background covers 8.9% of the sample. It can include empty cells and mechanism panels, so read it as spare backing area rather than a count of free moves.
- Does the board image show the order to move the blocks?
- No. A still image shows the colours and their layout, but not the block queue or the order the game offers. The video on this page is the exact clear; the measured breakdown is what the board costs to clear, not a tap-by-tap order.
- How is the Level 135 board laid out?
- The sample fills 64.1% of its 20x28 lattice and splits into 5 colours and 28 groups. The pieces are spread across the sampled rows (32.6% top, 37.3% middle, 30.1% bottom) rather than stacked in one band. The sample has no empty rows and no full-width corridor, so spare space is limited.
- What difficulty is Level 135 in Block Out?
- Level 135 is rated Intermediate difficulty in Block Out! - Color Sort Puzzle. Tiers run from Beginner (1-99) through Intermediate (100-249) and Advanced (250-449) to Expert (450 and up).
- Is there a video walkthrough for Block Out Level 135?
- Yes — the video on this page plays the complete clear of this board, so you can follow the block routes in real time.
- Why do I get stuck on Block Out Level 135?
- Most jams on Level 135 come from opening a second colour before the first is off the board. The sample holds 5 colours split into 28 groups, so every extra front costs a lane. Clear one colour at a time, keep the middle open, and treat the edges as waiting space.
- Does Block Out work offline?
- Yes. Block Out! - Color Sort Puzzle can be played offline once installed — there are no online requirements during normal play.
