How a round of craps works
The first roll is the come-out. Pass wins on 7 or 11 and loses on 2, 3 or 12; any other number becomes the point. The shooter then rolls until the point comes again (pass wins) or a 7 (pass loses). Don't pass is the mirror image, except that 12 on the come-out is a push.
P(pass) = 8/36 + Σ P(point) × P(point before 7) = 244/495

Questions
What is the best bet in craps?
The odds bet behind the pass line pays true odds and has no house edge, but you can only make it after a pass bet. Among bets you can make on their own, don't pass (1.36%) and pass (1.41%) have the lowest edge.
How often does the pass line win?
244/495 of the time, or 49.29%: 8 of 36 come-out rolls win straight away with a 7 or 11, and points are made before a 7 often enough to bring the total to 244 in 495.
Is this a real-money craps game?
No. It is a free simulator with play money and the real dice odds. Nothing is deposited or paid out.
Why does my result differ from the house edge?
Luck dominates over a few hundred rolls. Over 1,000,000 rolls of $10 pass bets our simulation lost 1.24% of the money bet, close to the 1.41% the maths predicts.
