Do I have to spend money to use NeonMob?

You don't have to spend anything to use NeonMob! Collect free packs, trade, discover art, and build a collection without ever spending a dime. Look for the blue "Open Free Pack" button and you can collect that series.

If you do want to get more than your daily allotment of free packs, you may choose to buy additional packs using credits, which are purchased under the "Buy Credits" button.
