How to Approach Block Out Levels 238 and 239

For Block Out levels 238 and 239, preserve an empty tube for temporary storage and avoid covering colors you still need to move. Before each transfer, check what the move will uncover and whether it leaves you room to sort.

Keep a tube open

Use an empty tube as a buffer when moving blocks that obstruct colors you want to group. Avoid filling every tube just to complete a partial stack; keeping a space open gives you somewhere to move blocks during later sorting.

If you move a block into an empty tube, continue grouping matching blocks there when possible. Don’t use the buffer in a way that leaves a needed color trapped beneath another color.

Sort without blocking access

Move a block onto a tube with a matching color when that move is available. If you need to use a different tube, check that it is empty or has a matching block on top. Before committing, look at the blocks the move will expose and make sure you still have room to reposition them.

For level 239, the draft’s suggested approach is to clear accessible top blocks first, then use the newly exposed matches to reorganize the board. Completing one tube at a time can reduce the number of unfinished stacks, but don’t do so if it uses up your only open space.

If you run out of moves, check whether an undo option is available. Use it to reverse a move that blocked your progress, then reassess the open space and the colors you can access.
