Onticoin is a virtual currency that only exists in Ontiville.
You can use Onticoin to pay rent, or to buy items in Ontiville shops relating to the Ontiville game experience.
There are multiple ways of obtaining Onticoin:
There are Quests, Jobs, Loot Chests, Cash Cans and fighting NPC's and other avatars (at your own risk).
Quests are little missions that NPC's all around the city give to you when you bump into them.
They can vary in their payout, however because of them being there 24/7, these are the primary way to collect Onticoin very quickly.
Jobs take longer than Quests, but you're guaranteed a much better coin payout when finished.
This is a fixed amount, think of it like a salary.
Loot Chests (Drops) can spawn in locations all round the city and in space.
They look like a glowing treasure chest symbol about waist-height on an average avatar;
bump them to have a chance in collecting a few Onticoin or ammo for an Ontiville weapon.
Cash Cans; Keep the city clean by clicking on waste bins (big or small). They don't earn much but "Every little makes a mickle".
Fighting; You can choose to rob any NPC, another avatar or destroy a vehicle for an unconventional way to earn coins, however the police will hunt you down, and your coins will be forfeit.
Quests are spread all over the city. If you see an NPC with a "?" symbol above them, bump into them and see what happens.
NPC's are spread all over the city, including on rooftops and inside buildings, even in space!
