Stackline

Take the crane controls and work out the right loading order. Every crate matters: buried freight, crowded bays and incoming deliveries turn a little toy yard into a planning puzzle.

Solve 80 handcrafted yards across eight chapters. Use HOLD, uneven bay heights, marked destinations and cargo that spans two bays. Handle bottom-only steel, top-only glass, fragile cardboard and colored-lid stacking rules.

Think at your own pace. Freight advances when you make a move, with no countdown timer. Retry and Undo freely, improve your medals and earn truck paints and crane looks. Try optional Daily Dispatch boards and use optional supplies when you want help.

Ads help support Stackline. Optional purchases provide coins and supplies. The Dispatch Pass removes automatic ads; optional rewarded ads remain available where permitted. No purchase is required for the core puzzles, Undo or retries.
