I am confused about this. I am new and placed a bet for the Knicks -10 and they won so I won that bet. Today I picked the Lakers -10 and they also won, but I lost this bet? What's going on. I also won with kansas vs Ohio for +3, even though they got only 2 more. How did that occur?
Please help.

Don't bet on something you don't understand. The way point spread works is after the final siren the points are deducted or added onto that teams total to get the new final score eg in that knicks game vs the cavs they won 91-75 so the final score after the knicks -10 is 81-75 which means you won the bet.
nba is tricky as opposed to football/soccer which is more predictable. still
