This is a Christmas game from Sugar-Free-Games.com. Santa is about to enter through the chimney and bring presents to the kids, but there's one problem: no one actually uses the fireplace and it is not connected to the chimney. You need to build blocks connecting them. Click on free spaces to build blocks there. If you make a mistake, you can destroy a block clicking on the bulldozer you have in the bottom right corner and then on the block you want to destroy.
