Gold

Gold is the currency used in Ninja.io. Gold is needed to buy customizations and to create a clan. However, there is nothing that you can buy that gives you an advantage. Buizerd, the creator of Ninja.io, has stated that "Ninja.io will not become pay2win."

Gold is earned by playing the game. Kills, flag caps, DM wins, TDM wins and CTF wins all yield gold. In addition, killing a player will occasionally cause that player to drop gold. Dropped gold can be picked up by registered players just like you would pick up items. Players will also eventually also get the ability to buy gold. Unlike items however, unregistered “guests” can’t pick up gold. You can also earn gold in the shop by watching videos(video=100 gold added to account with a 60 second cooldown before you can watch another video), however the daily limit is gaining 2,000 gold or watching 20 videos.

Gold can also be sent to friends/clanmates. the minimum gold you can send is 50, and the maximum amount is 1000. You can send up to 1000 gold an hour.
