The sample covers 74.3% of a 20x28 lattice: 8 colours, 0 empty rows and 47 separate colour groups.
blue 25.5% of the sample
Spread across the sampled board rather than parked in one corner.
green 23.6% of the sample
Spread across the sampled board rather than parked in one corner.
purple 8.4% of the sample
Spread across the sampled board rather than parked in one corner.
cyan 6.8% 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 6.4% of the sample
Spread across the sampled board rather than parked in one corner.
dark cyan 6.4% of the sample
Mostly around the edge, close to the doors and waiting lanes.
red 3.6% of the sample
Spread across the sampled board rather than parked in one corner.
dark green 2.6% of the sample
Spread across the sampled board rather than parked in one corner.
navy 16.6% 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 25.5% 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
cyan 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 board starts crowded
Only 16.6% 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.
8 measured colours
The sample contains 8 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 743 clear works
The sample fills 74.3% of its 20x28 lattice and splits into 8 colours and 47 groups. The pieces are spread across the sampled rows (36.3% top, 33.2% middle, 30.5% bottom) rather than stacked in one band. Dark cyan is the most divided colour, with 10 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 743 sits in the Expert tier and in the 721–760 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
Dark cyan is split into 10 groups. Clear the group closest to its door first; the far groups stay blocked until that run is finished.
Strategy note 3
74.3% of the sample is covered: enough room for one waiting lane, not two.
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
If a lane is blocked, clear the block at its mouth rather than pushing deeper into the jam.

Block Out Level 743 — frequently asked questions
- What colours are on the Block Out Level 743 board?
- The board image on this page breaks down into 8 main colours: blue (25.5%), green (23.6%), purple (8.4%), cyan (6.8%), orange (6.4%), dark cyan (6.4%), red (3.6%), dark green (2.6%). 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 743 board?
- Blue is the largest measured colour at 25.5% 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 743 board is empty?
- The dark board background covers 16.6% 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 743 board laid out?
- The sample fills 74.3% of its 20x28 lattice and splits into 8 colours and 47 groups. The pieces are spread across the sampled rows (36.3% top, 33.2% middle, 30.5% 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 743 in Block Out?
- Level 743 is rated Expert 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 743?
- 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 743?
- Most jams on Level 743 come from opening a second colour before the first is off the board. The sample holds 8 colours split into 47 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.
