The sample covers 43.2% of a 20x28 lattice: 9 colours, 0 empty rows and 63 separate colour groups.
red 13.1% of the sample
Spread across the sampled board rather than parked in one corner.
pink 12.4% of the sample
Spread across the sampled board rather than parked in one corner.
orange 11.8% of the sample
Spread across the sampled board rather than parked in one corner.
cyan 11.1% 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.
navy 7.5% of the sample
Spread across the sampled board rather than parked in one corner.
green 7.5% of the sample
Spread across the sampled board rather than parked in one corner.
dark orange 5.9% of the sample
Mostly around the edge, close to the doors and waiting lanes.
deep navy 5.9% of the sample
Spread across the sampled board rather than parked in one corner.
pale orange 3.9% of the sample
Spread across the sampled board rather than parked in one corner.
navy 20.9% 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: red
Red covers 13.1% 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.
There is spare space — use it deliberately
About 20.9% of the sample is dark background. That is more breathing room than the busiest boards get, so use an empty lane as a waiting spot instead of parking a block in front of a door.
9 measured colours
The sample contains 9 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 515 clear works
The sample fills 43.2% of its 20x28 lattice and splits into 9 colours and 63 groups. The pieces are spread across the sampled rows (30.2% top, 38.0% middle, 31.8% bottom) rather than stacked in one band. Red is the most divided colour, with 11 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 515 sits in the Expert tier and in the 481–520 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
Red is split into 11 groups. Clear the group closest to its door first; the far groups stay blocked until that run is finished.
Strategy note 3
Only 43.2% 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 515 — frequently asked questions
- What colours are on the Block Out Level 515 board?
- The board image on this page breaks down into 9 main colours: red (13.1%), pink (12.4%), orange (11.8%), cyan (11.1%), navy (7.5%), green (7.5%), dark orange (5.9%), deep navy (5.9%), pale orange (3.9%). 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 515 board?
- Red is the largest measured colour at 13.1% 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 515 board is empty?
- The dark board background covers 20.9% 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 515 board laid out?
- The sample fills 43.2% of its 20x28 lattice and splits into 9 colours and 63 groups. The pieces are spread across the sampled rows (30.2% top, 38.0% middle, 31.8% 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 515 in Block Out?
- Level 515 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 515?
- 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 515?
- Most jams on Level 515 come from opening a second colour before the first is off the board. The sample holds 9 colours split into 63 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.
