Our position

LineMath is intended for people aged 21 and over where sports betting is legal. Our calculators show math, not guarantees: expected value and arbitrage results are long-run or before-risk figures, and no tool here can promise a profit.

Healthy limits

• Only wager money you can afford to lose.
• Set a budget and time limit before you start, and stick to it.
• Never chase losses or bet to fix a financial problem.
• Use your sportsbook's deposit limits, cool-off, and self-exclusion tools.
