Racing Tracks

Racing tracks is a collection of puzzles where you must complete the race circuit.

The numbers along the edge of the grid indicate how many pieces of track are located in each row and column. Your job is to work out, by deduction, which way the track is supposed to follow and draw in the missing pieces, so the race car can reach the finishing line.

There are 150 circuits in total to complete, with varying difficulties, from easy, medium and hard.
