What each pool actually is.
Exacta · two horses, exact order.
First and second, in that order. A box buys both orderings. Field of N: N×(N-1) straight combos; double for a box.
Trifecta · three horses, exact order.
Win, place, show, in order. A 10-horse field has 720 straight trifecta combinations. Boxes and partial wheels expand coverage.
Superfecta · four horses, exact order.
First through fourth. A 10-horse field has 5,040 combinations. Pools are smaller and prices are larger; splits are rare but exist.
Pick 3 / Pick 4 · winners of consecutive races.
Pick the win horse in 3 (or 4) sequential races. Combinations grow multiplicatively across legs — an 8×7×9×6 sequence is 3,024 combos. Single-ticket coverage gets expensive fast.
Pick 5 / Pick 6 · the multi-race jackpot pools.
Five or six consecutive winners. If no single ticket hits all legs, the pool rolls into the next day — the carryover. Live carryovers →
Super High Five · five horses, exact order.
First through fifth. Most tracks run this as a jackpot pool with a frequent rollover. Combinatorial explosion: a 10-runner field has 30,240 combos.
