Level 155 throws players into a twisted layout with frozen blocks tucked in the left corridor and a grid of tightly packed middle pieces. The challenge lies in unclogging the central greens and purples while leaving enough vertical space for the frozen block to drop cleanly.
Problem: The blue frozen block is stuck between a red vertical and green horizontal piece.
Solution: Slide the green block down and shift the red vertical right. This opens the first lane for the frozen block.
Problem: Multiple green and purple squares overlap in the central space, blocking future slides.
Solution: Start by sliding the yellow horizontal block up, then alternate purple and green shifts to free pathways.
Problem: The orange 2×3 block can easily trap the exit if moved too early.
Solution: Keep orange in place until both frozen blocks are aligned above the exit, then slide it away at the last step.
Final slide into the lock slot to finish the level.
Level 155 is a grid-control puzzle where precision matters more than speed. Keep the bottom clear, slide the frozen block step by step through the left corridor, and save the orange shift for the endgame. With this method, the puzzle becomes far less overwhelming.
