This challenging visual puzzle will appeal to lovers of logic and deduction brain teasers. How To Play: A map grid shows two towns, typically A and B. The objective of the puzzle is to lay down tracks to connect the two towns. Numbers around the outside of the grid tell you how many pieces of track are to be placed in each row and column. You can only use straight (horizontal and vertical) and curved (right and left) rails and the track cannot cross over itself. There is something very satisfying in the laying down of tracks. The puzzles are arranged with varying levels of difficulty, where difficulty is largely dependent on the size of the map grid (from 6x6 to 10x10). Puzzles included cover three levels of difficulty: 70 Easy, 70 Moderate, and 60 Difficult.
