Hidoku

Hidoku is a logic puzzle used quite a lot. These puzzles are excellent, as Djape and Philipp Hübner say. The object is to make a joined up chain of numbers from 1 to the largest number (both circled). The chain can move in any of the eight directions (left, right, up, down, up-left, up-right, down-left and down-right) and the chain can cross. Beware that some puzzles are 1-25 and some by Djape are 1-300! I hope you enjoy playing this puzzle. The sample shown is 1-64.
