What are the prices for the millionaire center pet slots?

Also could someone confirm that the only way to buy pet slots is with CSC or through the millionaire center. I just want to be sure I'm not forgetting another option.

here are some news posts which have pricing schemes for MC pet slots: 6-10, 11-15 i don't remember when the pet slots were first added to the MC but i'm pretty sure the pricing scheme is 20m, 40m, 60m, 80m, 100m for the first 5. apparently it goes up to 25 per the user dashboard but those were the only two news posts that came up when i googled "subeta millionare center pet slots" so shrug the only other ways are loyalty boxes & random rewards from site events, i think? both sort of 'soft' purchases through simply remembering to log in, or being active enough to participate during the event time period. edit: fist appeared in july 2015

MC slots start at 20 mill and go up by 20 mill each purchase up to 10, then resets. So slot 11 is 20 million again. You can get via CSC, you can use your loyalty box to exchange for a pet slot totem, and quest a thons have given a slot.

Thank you both that really helps. I remembered there was a reset but I couldn't remember the prices.
