Rush Sports Is Now Clash Sport — New Game, New Look, New Chain

The game: 60-second Up/Down calls on every live sport

Pick any live game, choose a stake from your USDG balance and tap UP or DOWN. Your round starts on the next 5-second mark about 30 seconds later and runs exactly 60 seconds. If the game’s live win probability finishes higher, UP wins; lower, DOWN wins. A perfectly flat finish loses.

Payout scales with the move: stake × a multiplier from 1.01x to 33x, priced against the market’s recent volatility — a small nudge your way pays a little, a big swing pays a lot. Every live Polymarket sport and esport is playable: football, basketball, tennis, cricket, American football, hockey, UFC, CS2, League of Legends, Valorant, Dota 2 and more. Esports games show the live stream right next to the chart.

• Up/Down against a shared house LP — every call is taken instantly
• Payout = stake × 1.01x–33x, scaled by the size of the move, less 2% of the profit; flat or wrong way loses
• Bets in USDG from an in-app balance: deposit once, withdraw any time
• Every losing bet mints CLASH, the fair-launched token

A house that started at $0

Every call is taken by one shared house LP. It started at $0, accepts no deposits and fills only from player losses. Winners always get their stake back immediately; if the LP can’t yet cover a win’s profit, the unpaid part becomes a first-in-first-out ticket that later losses repay before anything else.

Fees are 2% of every winning profit (deducted from the winner) and 2% of every loss (carved from the house’s gain, not added to the loss), split 50% to CLASH stakers and 50% to the treasury — so the team earns exactly 1¢ per $1 of losses or winning profit. LP cash, the ticket queue and every bet can be read on-chain.

CLASH: a fair launch minted to losers

CLASH supply started at zero, with no presale and no team or investor allocation. It is minted only to losing bets — 100 CLASH per $1 lost — and the rate decays once the house LP’s gross House Funds first pass $2M.

At launch CLASH is non-transferable: you can stake it for 50% of all fees in USDG, unstake it and claim rewards, but you can’t send or trade it. Transfers open automatically 14 days after the house’s gross equity — LP equity plus cumulative equity allocated to stakers, with donations to the house counting too — first reaches $5M. That is an accounting milestone, not cash held or revenue. Nobody can delay the rule, but the contracts are upgradeable with 24 hours’ public notice, so it could change through a scheduled upgrade. Unlocking only permits transfers: it doesn’t create a trading venue, a market price or guaranteed liquidity.

Built on Robinhood Chain

Clash Sport is built on Robinhood Chain, an EVM-compatible network built on Arbitrum technology. Fast blocks and gas measured in fractions of a cent make it practical to place, price and settle a 60-second round on-chain without the chain getting in the way. Any standard EVM wallet works, and Robinhood Wallet connects through WalletConnect.

Deposits, bets, boundary prices, payouts, tickets, CLASH emission and staking are all contracts anyone can read. Withdrawals, settlement, refunds and ticket claims can never be paused.

A new face for a fast game

The identity is comic-arcade: cream paper, ink outlines, halftone dots — and two colors that mean something. Lime is UP. Pink is DOWN. The starburst in the middle is the moment your call meets the next minute of the game.

Where this came from

Rush Sports started on Solana as a house game: call a short odds move and get paid from a pool. The first Clash Sport build on Robinhood Chain tried a different format and paired players head-to-head. The current build keeps the Clash name, look and chain, and brings back the Rush-style Up/Down mechanic — rebuilt with a house LP that starts empty, payouts that scale with the move, USDG balances and a fair-launched token. The earlier builds are frozen and preserved.

What is live now, and what is next

Everything above is live on Robinhood Chain testnet today — calls on live games, the house LP, tickets, CLASH emission and staking — and free to play with test USDG from the in-app faucet (1,000 per day) plus a little testnet ETH for gas. Mainnet follows an external audit, because real money deserves real security. No dates until they are certain — shipped beats promised.
