Sports betting guides
Updated
These guides explain, in plain language, how bettors turn promotions, price differences and market prices into expected profit, and where each idea breaks down. Each one names its risks (limits, voids, stale prices and taxes) and points to the matching calculator and to the live dashboard.
All guides
Arbitrage betting
How arbitrage betting works, with a checked $500 example, exchange fee math and what can void a lock: limits, stale lines and settlement differences.
Bonus bets
A bonus bet pays profit, not your stake. See what one is worth, the hedge formula that locks cash, and how exchange fees, expiry and odds limits change it.
Expected value betting
What expected value means in betting, how fair odds come from removing the vig, why closing line value is not proof of profit and how much data you need.
Prediction markets
How sports prediction markets differ from sportsbooks: who regulates them, where courts contest them, what they cost and how they settle. Dated by state.
Sign-up bonuses
Bet-and-get, first-bet refund and exchange credit offers compared by what they are worth, with state variants, end dates and a checked-on date for each.
Sportsbook promos
Profit boosts, parlay boosts, no-sweat bets, early-win tokens and bonus bets: the formula for each, the caps that limit it and which can be hedged.
Keep going
The calculators put each guide’s formula to work on your own numbers. See also the calculators, state-by-state availability, sportsbooks and exchanges, or open the live dashboard for today’s promo plays and arbitrage.
