Superfectas are not my thing but there are 116,280 combinations in a 20-horse field. With 20 horses, it results in 380 possible Exacta outcomes and 6,840 Trifecta combinations. Please don't call it a crapshoot since rolling a pair of dice only has 11 possible outcomes.
Each year, the Kentucky Derby (G1) has a field of 20 horses going a distance of ground that none have ever attempted.
