Very Hard left purple and cyan cluster layout
Color Block Jam Level 688 Solution
This solution matches the Very Hard Level 688 board with the wide upper lanes, a dense left purple/cyan cluster, and central wooden locks. Open the upper-right green route first, keep the left cyan column connected, reduce the central lock row before moving the bottom red and blue pieces, then clear the late yellow and purple pieces before the level-complete panel at about 2:20.

Start only if your game shows the Level 688 Very Hard board with the left purple/cyan cluster, central wooden locks, and bottom red and blue exit lanes.
Checkpoint: The board matches the opening frame, and the left cyan column is still connected to the center.
Watch at 0:05Move the upper-right green piece into the top lane before shifting the orange and yellow blocks around it.
Checkpoint: The upper-right lane is open and the central lock row is still reachable.
Watch at 0:15Slide the left cyan pieces only far enough to keep their column connected; do not park purple across the left exit yet.
Checkpoint: Cyan remains on the left side and the purple cluster has room to rotate.
Watch at 0:20Push the green horizontal block across the top row and use the new space to move the small blue and cyan pieces on the right.
Checkpoint: The right wall opens while the lower red and blue pieces stay accessible.
Watch at 0:35Begin clearing the central lock row by moving the right-side pieces out first, then slide the red bottom piece only after the center opens.
Checkpoint: The central wooden row has fewer blockers and the bottom red piece still has an exit route.
Watch at 0:45Move the blue bottom piece through the lower middle lane, then return the green block to the right side as a temporary spacer.
Checkpoint: The blue lower lane is open and the center is not sealed by green.
Watch at 0:55Rotate the left purple pieces through the opened center instead of sliding them directly into the exit wall.
Checkpoint: Purple has moved inward and the left cyan pieces still have a path.
Watch at 1:05Use the open middle to pull the cyan and blue pieces away from the lock row, then slide the red piece across the bottom.
Checkpoint: The lower middle is mostly open and the remaining lock row is exposed.
Watch at 1:20Move the yellow pieces into the right and lower lanes only after the blue pieces have cleared their path.
Checkpoint: Yellow is staged safely and the right side remains open for purple.
Watch at 1:30Send the upper yellow piece through its top-side route, then keep the lower yellow block parked away from the green exit.
Checkpoint: Yellow particles appear near the top and the center remains clear.
Watch at 1:45Move the right purple block through the opened side path before shifting the green block into the lower-right lane.
Checkpoint: Purple has a clear side route and green is not trapping the final yellow piece.
Watch at 1:55Gather the last yellow, purple, blue, and green pieces near their matching exits without filling the center again.
Checkpoint: Only a small late cluster remains around the lower middle and right side.
Watch at 2:05Clear the remaining blue/cyan pieces through the side exits before moving the last green block.
Checkpoint: The left and right side lanes are open, with only yellow/green cleanup left.
Watch at 2:10Send the final green piece through the green exit after the yellow route is no longer blocked.

Common mistakes
- Moving purple into the left exit wall too early, which cuts off the cyan column and traps the center.
- Clearing the bottom red or blue piece before the central lock row is exposed.
- Treating the Very Hard label as a reason to rush the top pieces; this board needs the right-side green route opened before the late yellow and purple exits.
