Flag bet mechanics & rules
An exotic system bet blending multi-tier parlays with conditional roll-over stakes.
Payouts are determined by multiplying the unit stake by the cumulative price of each winning selection or combination line. If any selection is scratched or declared non-runner/void, standard rules settle that leg at neutral odds of 1.00.
Worked example: Flag bet
Staking $2.00 per bet ($46.00 total) across 4 moneyline games: landing all 4 picks at +100 returns $144.00 on the Yankee portion and $144.00 on the SSA portion, totaling $288.00 ($242.00 net profit).
Always check bookmaker maximum payout caps and race terms before placing high-volume system bets.

CALCULATOR QUESTIONS
US Flag bet questions
How does a void leg affect a flag bet?
When a selection is void, postponed, or scratched, that specific leg counts as a 1.00 multiplier (money returned for that leg), and the multiple bet rolls down into the remaining folds.
What is the difference between unit stake and total stake?
Unit stake is the amount wagered on each individual bet or line. Total stake equals the unit stake multiplied by the total number of bets in the multiple or system wager.
Are gambling and betting winnings taxed?
In the US, gambling winnings are fully taxable as ordinary income by the IRS and state tax authorities, with Form W-2G issued on qualifying high-multiplier wins.
