System bets are single slips that contain many wagers across the same set of selections. Instead of one big accumulator that requires every leg to win, you cover every smaller combination too — doubles, trebles, fourfolds, fivefolds and so on. The cost is many unit stakes (a Yankee is 11, a Heinz is 57, a Goliath is 247), but the slip can still pay out on partial winners. The "Lucky" subfamily (Lucky 15, Lucky 31, Lucky 63) layers singles on top of the same structure, plus standard bookmaker bonus payouts on single-winner and all-winners outcomes.

Four questions in order:
The calculator above defaults to Lucky 15 — the most-played full-cover bet in UK retail. Set four selections all at 5/2 (3.50 decimal) with a £0.50 unit stake — total outlay £7.50. If all four win:
Total return before bonuses = £204.53 on £7.50 outlay — a profit of £197. Add a typical 10% all-winners bonus and total becomes about £225, profit £217.50 — roughly 29× the stake. The bonus uplift alone adds £20 to the result.

Every leg you add to a system bet compounds the bookmaker's margin. A 4-leg full-cover bet with each leg carrying a 4% overround gives the bookie about 17% expected take on the fourfold alone; an 8-leg Goliath pushes that toward 33%. Bookmaker bonus payouts narrow the gap but rarely close it entirely — the maths is structural, not promotional. The foundational read on how bookmaker pricing works walks through exactly why this compounds the way it does — essential before stacking into any system bet deeper than a Trixie.
