# Game of Splits

> Game of Splits is a set of small onchain games on Robinhood Chain (chain id 4663). Players pay in USDG. One contract, FairCore, takes every payment, splits it once, and holds winnings until the winners claim them.
> 60% of each shot goes to that round’s Purse. The other 40%, the Greenwood, goes to the Locksley Vault (18%), the Alms (8%), the Bonfire (7%) and the Toll (7%).
> The live site is https://gameofsplits.fun. These docs are at https://docs.gameofsplits.fun and https://gameofsplits.fun/docs.

## How a round works

- A Pass locks 5,000 $WIF for at least 24 hours. Shots themselves are paid in USDG. Winnings wait in FairCore until the wallet calls claim.
- Last Arrow. Rising-price shots on a timer. The last shot before the clock runs out wins half the Purse. The 10 shots before it share 35%, and the wallet with the most shots in the round gets 15%.
- Sheriff’s Seat. One seat per day, midnight to midnight UTC. The top 3 by time held split that day’s Purse 75% / 20% / 5%.
- Robin Among Thieves is a repeated share-or-steal round. Each round two outlaws each stake 5 USDG. Both share and each receives 4.75, plus a sharing-pot bonus when one is available. One steals and the thief takes 9.50. Both steal and both lose, and 9.70 goes to the Sharing Chest. The match fee is 0.50 USDG: 0.20 to the Sharing Chest and 0.30 to the Locksley Vault.
- A Robin round lasts 30 minutes. Pairing is 3 minutes, commit is 10, reveal is 10, then the round settles.
- Commit keccak256 of the move and a salt, then reveal the move and the salt. No reveal forfeits the pot.
- Alms. Pass holders vote which charity receives the Alms.
- Games run in chapters of at most 35 days. Claiming still works between chapters.

## The flywheel

- Players lock a Pass, then shots fill the Purses. A larger Purse draws more shots.
- The Greenwood is the other 40%. The Bonfire and the Vault buy $WIF. Some is burned and some is held. The Vault’s 18% is four equal quarters: buy and hold, liquidity USDG, buy and burn, and reserve.
- 8% goes to a charity the players vote for.
- The Toll is protocol revenue.
- Burns and buys do not guarantee a price. Marks are points for playing. The loop only turns if people want to play.

## $WIF

- $WIF is the play token and the buy token on mainnet. Address 0x5173b8eA6923c2d40267890D45C46a3480954773. USDG is 0x5fc5360D0400a0Fd4f2af552ADD042D716F1d168 (6 decimals).
- A Pass locks 5,000 $WIF. A Robin licence locks 1,000 $WIF per outlaw and returns when that outlaw is retired after at least 24 hours.
- Shots are paid in USDG, not in $WIF.
- Each Trading Post swap pays a 0.2% (20 bps) game fee to the FeeSplitter: 50% to the Locksley Vault, 40% to buying and burning $WIF, and 10% to the Toll. Bridging pays a separate 0.20% (20 bps) app fee.
