Fomo3D Arbitrum ($P4D) is a lottery game built on Arbitrum in which the last person to buy a key at the end of a round wins the pot.
During a round, people can purchase 1 or more keys, which adds time to the countdown and marks them as the current "exit scammer". With each key purchase during the round, the key price increases slightly, as does the pot.
Players receive a stream of passive income from the game as keys are bought during the round. The proportions of how key purchases are distributed is explained on the Teamnomics page.
The timer starts at 24 hours and increases by 30 seconds for every key that is bought. When the timer reaches zero, the last person who bought a key takes home a large chunk of the entire pot! (F3D players/PoSH4D stakers get a piece too, so it's possible to "win" even if you're not the last to buy a key!)
Players can select from one of four teams which will determine certain rules in the round! This can completely change the game. See the Teamnomics page.
PoSH4D stakers will receive dividends on each key purchase and at the end of the round.
Players can buy a vanity URL and/or refer their friends to the game for extra rewards.
Buying keys offers you a % chance to receive an "airdrop", winning ETH from a growing side-pot!
