Your challenge is to negotiate round the board from blue square to red square using the knight's move (from chess) and the black stepping stones. The knight's move is defined as two squares across plus one square up/down (or two up/down and then one across).
Your current position is marked with a small white square. Only black squares can be moved to, and then only those black squares which are a knight's move away. For added difficulty only a 5 × 5 square area of board is ever visible, centred on your current position.
