Puzzle 3 (APP5) Solution

The pairs of matching numbers can each be connected by a single path within the upper grid (as in the free iPhone game Flow). Once the grid is filled in with the paths of numbers, use an appropriate rotation cypher on the letters in the lower grid to reveal the message:

W  E   L   L   I   S   U   P   P O   S   E   Y   O   U   H   A   V E   S   O   L   V   E   D   T   H I   S   P   U   Z   Z   L   E   H E   A   D   T   O   T   H   E   A R   T   M   U   S   E   U   M   L A   K   E   T   O   C   L   A   I M   Y   O   U   R   P   R   I   Z E   F   A   R   E   W   E   L   L
