The sample covers 85.0% of a 20x28 lattice: 10 colours, 0 empty rows and 68 separate colour groups.
blue 23.3% of the sample
Spread across the sampled board rather than parked in one corner.
purple 14.9% of the sample
Spread across the sampled board rather than parked in one corner.
green 13.9% of the sample
Concentrated in the central half of the sample, so these pieces have to cross the busiest lanes.
pale blue 13.0% of the sample
Spread across the sampled board rather than parked in one corner.
white 7.4% 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 7.4% of the sample
Spread across the sampled board rather than parked in one corner.
navy 6.9% of the sample
Mostly around the edge, close to the doors and waiting lanes.
red 6.1% of the sample
Concentrated in the central half of the sample, so these pieces have to cross the busiest lanes.
light blue 4.0% of the sample
Spread across the sampled board rather than parked in one corner.
deep green 3.2% of the sample
Spread across the sampled board rather than parked in one corner.

How to read this board
Start from the largest colour: blue
Blue covers 23.3% 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.
Protect the middle: green
Green 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.
Rim colours are doors, not extra blocks
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.
How the Level 305 clear works
The sample fills 85.0% of its 20x28 lattice and splits into 10 colours and 68 groups. The pieces are spread across the sampled rows (34.0% top, 36.3% middle, 29.6% bottom) rather than stacked in one band. Blue is the most divided colour, with 12 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 305 sits in the Advanced tier and in the 281–320 block of this guide. Advanced boards usually have more blocks than comfortable free space. Every parked block costs a lane, so plan two or three moves ahead and keep the board's center clear. 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 12 groups. Clear the group closest to its door first; the far groups stay blocked until that run is finished.
Strategy note 3
85.0% of the sampled lattice is covered. At that density one parked block can close the only route to a door.
Strategy note 4
Clear the edge pieces before the middle ones; the centre is where every route has to cross.
Strategy note 5
If two colours are split into several groups, finish the smaller colour first so it stops competing for lanes.

Block Out Level 305 — frequently asked questions
- What colours are on the Block Out Level 305 board?
- The board image on this page breaks down into 10 main colours: blue (23.3%), purple (14.9%), green (13.9%), pale blue (13.0%), white (7.4%), orange (7.4%), navy (6.9%), red (6.1%), light blue (4.0%), deep green (3.2%). 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 305 board?
- Blue is the largest measured colour at 23.3% 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 305 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 305 board laid out?
- The sample fills 85.0% of its 20x28 lattice and splits into 10 colours and 68 groups. The pieces are spread across the sampled rows (34.0% top, 36.3% middle, 29.6% 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 305 in Block Out?
- Level 305 is rated Advanced 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 305?
- 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 305?
- Most jams on Level 305 come from opening a second colour before the first is off the board. The sample holds 10 colours split into 68 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.
