The games, the 21 Vyper calculators and the futures market that exercised the first FP127.
These were built to exercise the first FP127. They still run. They are not maintained, and they call the legacy Huff address at 0xfae694D0c2c44181791F838c54Ed64C3151FfE30, so their results are Huff-era results. Open one and it mounts below the cards, exactly as it was.
calculators

Time-weighted payout contracts with customizable distributions
Transfer ownership of unlocked futures without the marketplace
Deposit ETH, pick a distribution and lifetime. A contract is deployed holding your ETH.
Value accrues to the current owner according to the distribution curve over time.
Transfer ownership to extract the accumulated payout. The remaining balance passes to the new owner.
At end of lifetime, the final owner can withdraw all remaining ETH.
Payout uses the distribution's probability density function:
payout = balance × ∫[pdf(t)] dt
new_balance = balance - payout
Lifetime: 5 minutes to 1000 years
Minimum value: 0.0001 ETH
Fees: None
