Fomo3D · interactive mechanism simulation

Players buy keys → each buy raises the key price and adds seconds to the countdown → proceeds split into the jackpot, pro-rata dividends to existing keyholders, and the next round's seed. Whoever holds the last key when the timer hits zero wins the pot. Edit the parameters, or trigger the block-stuffing attack that actually ended round 1.

Illustrative simulation. The 24-hour round timer, 30-second extension per key, and roughly-half jackpot split are compressed here to a ~60-second round so the mechanism is watchable; proportions and timing are otherwise randomized for visualization — not live onchain data. "Trigger block-stuffing attack" replays how round 1 actually ended: a player flooded blocks with high-gas transactions so no one else could buy a key before the timer expired.
