Slide the surrounding cars out of the way so the red car can reach the exit on the right edge.
Each car can only slide along its own length — horizontal cars left/right, vertical cars up/down. Drag any car along its axis to slide it as far as the next obstacle. The red target car has to reach the right edge of the board to escape. Each level adds an extra blocking car; clearing a level scores 100 points plus a bonus for finishing in fewer moves.
Trace the exit corridor first, not the cars. Look at row 3 (the red car's row): every vertical car standing in that row is what's stopping you. Plan which direction each of those verticals will slide BEFORE you make any move.
Move from the back of the queue forward. The car closest to the exit usually needs to clear last, because moving it first removes the only space the next blocker can slide into. Work from the right-most blocker backward toward the red car.
No waste-move resets — undo by sliding back. Cars slide both ways along their axis, so an accidentally-bad move can be reversed without restarting the level if you catch it immediately.
Later levels lock-stack: solving one blocker creates space for the next. Don't try to picture the whole solution at once. Get the back vertical out of the row, then look fresh at the smaller puzzle that's left — recursive simplification beats whole-board memorization.
