Won by playing "Power Pets".

These coins were originally won in the PnF Games 2016. You can now win them in size 4 by playing "Challenge" in "Power Pets", where one, two or three may be awarded for good "form". The type you win depends on the skill your pets are using. Each coin corresponds to one of the original set of "starter" pets. If one of those pets is playing, it will win its own coin. Other pets will win one of the coins associated with the starter pet which uses the same skill. You can also buy or sell any size in the Seasonal Shop and size them up.
