Bet Builder / Same-Game Parlay

Bet builders price custom combinations within one match — result + scorer + cards + corners — using correlation models to quote a single price.

Why every operator pushes it

Margins multiply across correlated legs whose fair joint probability is genuinely hard to assess, holding several times straight-bet rates; it’s simultaneously beloved by recreational bettors (narrative betting — “this exact game script”) and by finance. Correlation mispricing occasionally leaks +EV combinations, patched quickly. Regulatory attention is rising with product share.
