Haven't seen this one before - Garcia River Casino has a Winner's Club card
here's a link to the casino's website: http://www.thegarciarivercasino.com/index.html

Win-River now has "Win-River Resort & Casino" on their slot cards, same basic design except for the casino name change

Robinson Rancheria - found Sapphire and Ruby levels of the latest cards that hadn't been reported earlier

Table Mountain has a Platinum level with the ABL mark dated 2013 that wasn't previously reported.

Chukchansi apparently went back to their previous cards after using up the 10th anniversary cards

Spotlight 29 moved the reverse logos down under the text near the bottom of the card. So far have only found the yellow/orange base level with the new reverse. If anyone finds other levels like this one please let me know and/or send scans.

Colusa moved the reverse text left apparently to make room for a player photo. Trying to find out if there are any other levels beyond the base Colusa Rewards card.

Cahuilla changed the reverse text, web address was previously in the bottom right corner on the back and is now above the logo at the bottom of the paragraph.

Scans for all the newly found/reported cards have been submitted to the ChipGuide and should be online in a few days.
