It wouldn't be the first puzzle reward for a loyalty program.

Evidence is appearing that points to a potential release of a Twilight Princess-themed Picross title as a My Nintendo reward.
German developer Cellenseres first located icons for a Twilight Princess Picross, then managed to obtain the game's title screen on March 4. Listings for the title are on Nintendo servers in North America and Europe (may have to allow a certificate temporarily).
The Japanese version of Club Nintendo had an exclusive version of Picross as a reward during its time, but this appears to be an international release. The date given for release is March 31, but that is subject to change.
