This is a construction site. It is a game to fill all the stones in the hole. The bulldozer can only push the stone forward. Operate the bulldozer well and move the stone to the hole position. To move the bulldozer, drag the movement path with your finger from the position of the bulldozer. The route is displayed as a red line, so release the finger and the bulldozer will start moving. If you notice a mistake before releasing your finger, it will be canceled if you do not move your finger for 3 seconds.

Puzzle Maker World's advantage is update cadence (every 3 days vs every 10 months). On price, device support and iOS requirement there is nothing between them.
