Well... that's pretty vague. I'll guess that you went either right or left and ran out of potential moves.
The two sides join up eventually and you will get the pieces you need to cover the remaining pegs. So try going up to the room with the red carpet and go the other direction. Just make sure you have not missed any secret tiles.
