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 one more car until level 6 (seven besides the red car at most); after that, levels get harder through the shrinking time limit. Clearing a level scores 100 points, plus 10 for every move under 25, plus 25 × the level number.
Each level has a time limit shown at the top: 60 seconds for level 1, 1.5 seconds less for every level after. Run out of time and the run ends; clear all 40 levels to finish.
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.
Plan before you drag — moves are points. Every move under 25 is worth 10 bonus points, so a level solved in 5 moves earns 200 more than one solved in 25. A useful rule of thumb: check whether each vertical blocker has a free cell to slide into above or below the red row; if one is boxed in by another car, free that car first instead of shuffling pieces at random.
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.
