Same-game multi
Also known as: SGM, Same-match acca
A specific accumulator structure where every leg comes from the same single event — e.g. a five-leg SGM on a Premier League match (BTTS + Over 2.5 + Liverpool to win + Salah anytime + 10+ corners). The bookmaker prices SGMs using a custom correlation model rather than naive odds multiplication. Margins are typically higher than equivalent multi-match accumulators.
