ArbPlay

ArbPlay is a real-time sports arbitrage ("sure bet") scanner built for the Greek betting market. It watches odds across the major Greek-licensed bookmakers (Stoiximan, Novibet, Pamestoixima, Bwin, Fonbet, Superbet, Elabet and Allwyn / OPAP Store) alongside betting exchanges and prediction markets, and shows every combination of back and lay bets that locks in a margin whatever the result, provided each leg is placed at the quoted odds.

Instead of building spreadsheets and refreshing a dozen betting sites, you open one dashboard. Live and pre-match football, tennis and basketball are covered, and the board updates in sub-second time, so you see an opportunity while it still exists. Each row tells you what to bet and where: the back bet at the bookmaker, the cover on the exchange or prediction market, the stakes for both, and the result under each outcome.

What you get:

A live arbitrage board with filters for sport, bookmaker, market, lay venue, time and minimum margin.
A built-in stake calculator. Enter your capital and ArbPlay sizes each leg, accounts for exchange commissions and prediction-market fees, and shows the profit in euros for every outcome.
A fill check that compares the size you need with the size actually available at the quoted price, so you know whether a bet can be placed in full.
Instant alerts in the app and on Telegram when an opportunity matches your own rules: sport, minimum margin, bookmaker and minimum available size.
Allwyn / OPAP store codes shown next to the event, so a retail bet can be found in a shop.
Market Movers, a public board of the day's biggest odds drops and rises across Greek bookmakers.
The public site also has free guides in English and Greek on how arbitrage works, whether it is legal in Greece, how to calculate a sure bet, and an interactive arbitrage calculator.
