Club Nintendo’s game rewards have been reset for the month, and two new games are now available in exchange for coins. On the DSiWare front, you have Art Academy: First Semester, which is art tutor software. This can be redeemed for 150 coins, but you’ll need a 3DS to download it.
On the WiiWare end, you can pick up Mario Party 2 (N64) for Virtual Console. This will set you back by 150 coins, too.
Both games can be availed until February 29th, after which new ones will be made available.
