The sample covers 52.7% of a 20x28 lattice: 10 colours, 0 empty rows and 56 separate colour groups.
purple 16.3% of the sample
Spread across the sampled board rather than parked in one corner.
blue 16.3% of the sample
Sits almost entirely on the outer rim, where the door slots are. Treat it as a rim or door colour rather than another block group.
orange 13.2% of the sample
Spread across the sampled board rather than parked in one corner.
pink 12.2% of the sample
Mostly around the edge, close to the doors and waiting lanes.
red 11.9% of the sample
Spread across the sampled board rather than parked in one corner.
green 10.8% of the sample
Spread across the sampled board rather than parked in one corner.
light red 7.1% of the sample
Spread across the sampled board rather than parked in one corner.
dark grey 5.4% of the sample
Mostly around the edge, close to the doors and waiting lanes.
white 3.7% of the sample
Sits almost entirely on the outer rim, where the door slots are. Treat it as a rim or door colour rather than another block group.
medium green 3.1% of the sample
Mostly around the edge, close to the doors and waiting lanes.

How to read this board
Start from the largest colour: purple
Purple covers 16.3% 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.
Rim colours are doors, not extra blocks
blue and white appear almost only on the outer rim. They mark door slots or trim; do not count them as another group of pieces to clear.
The pieces cover the sampled board
No flat dark background was detected in the sample, so the pieces fill the measurable board area. Treat the first few moves as a search for any lane that is already open.
10 measured colours
The sample contains 10 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 661 clear works
The sample fills 52.7% of its 20x28 lattice and splits into 10 colours and 56 groups. The pieces are spread across the sampled rows (22.4% top, 33.2% middle, 44.4% bottom) rather than stacked in one band. Purple 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 661 sits in the Expert tier and in the 641–680 block of this guide. Expert boards are the tightest: narrow lanes, moving elevators and generators that refill space you just cleared. Clear one color completely before opening another front, and restart early if the board jams. 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
Purple 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
Only 52.7% of the sample is covered, so the edges can hold waiting blocks while the centre stays open.
Strategy note 4
If two colours are split into several groups, finish the smaller colour first so it stops competing for lanes.
Strategy note 5
Solve one colour at a time instead of pushing several blocks around at once.

Block Out Level 661 — frequently asked questions
- What colours are on the Block Out Level 661 board?
- The board image on this page breaks down into 10 main colours: purple (16.3%), blue (16.3%), orange (13.2%), pink (12.2%), red (11.9%), green (10.8%), light red (7.1%), dark grey (5.4%), white (3.7%), medium green (3.1%). 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 661 board?
- Purple is the largest measured colour at 16.3% 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 661 board is empty?
- No flat dark background was detected in the sample, so the pieces cover the measurable board area. There is no measured empty-space figure for this board.
- 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 661 board laid out?
- The sample fills 52.7% of its 20x28 lattice and splits into 10 colours and 56 groups. The pieces are spread across the sampled rows (22.4% top, 33.2% middle, 44.4% 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 661 in Block Out?

- 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 661?
- Most jams on Level 661 come from opening a second colour before the first is off the board. The sample holds 10 colours split into 56 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.
